DAVET / INVITATION

Değerli Meslektaşlarım, Organizasyon komitesi adına sizlere Türk Otoloji Nörotoloji Derneği’nin düzenlediği 8.Ulusal Otoloji Nörotoloji Kongresine hoş geldiniz demekten onur ve mutluluk duyuyorum. Konuşmama bağımsız ülkemizi, bizim bilim insanı olmamızı sağlayan özgür düşüncenin yolunu açan kurucumuz Mustafa Kemal Atatürk’ü ve çalışma arkadaşlarını ve ülkemizde Kulak Burun Boğaz biliminin öncülerini saygıyla anarak başlamak istiyorum. Kongremizin sanal ortamda olması, her ne kadar sizlerle yüz yüze buluşmayı, başarılı bir kongrenin yarattığı neşeyi ve bilimsel meydan okumanın hazzını aynı ortamda paylaşmayı engellese de farklı fırsat pencerelerinin açılmasını da sağladı. Bu organizasyonda normal bir kongrede bir araya gelmesi çok zor olan bir ekibi aynı programda buluşturduk. Sabah 8:00’den akşam 18:00’e kadar 3 salon neredeyse soluksuz akan bir program ile farklı ülkelerden 42, ülkemizden 136 bilim insanını bir araya getirdik. Bildiriler, uluslararası bir konsey tarafından değerlendirildi. Özet kitabını ve sunumları İngilizce olarak hazırladık. Kongremize 75 bildiri kabul edildi. Masrafların azalması da, katılım ücretlerini herkes için uygun düzeylere indirmemize fırsat sağladı. Bu kongrenin bilimsel seviyesi Otoloji Nörotoloji alanında çalışan bilim insanlarının bilgi birikimini ve dinamizmini yansıtmaktadır. Yoğun bir çalışma döneminin ardından bu açılış töreninde, kongrenin gerçekleşmesine katkısı olan büyük ekibe teşekkürlerimle sözlerime devam etmek istiyorum. En başta kongremizin kapsamı ve niteliğine büyük katkı yapan, her sorunda yanımda olan dernek başkanımız Sayın Prof. Dr. Nuri Özgirgin’e güçlü ve koşulsuz desteği için çok teşekkür ediyorum. Bu kongrenin düzenlenmesi sırasında bana güvenlerini ifade edip, destek olan Otoloji Nörotoloji Derneği yönetim kuruluna teşekkür ediyorum. Bizleri kırmayarak görevleri kabul eden, çok kısa bir zaman kalmasına rağmen hızla organize olan, konuşmacılarımıza, moderatörlerimize ve oturum başkanlarımıza teşekkür ediyorum. Gönderilen bildirileri zamanında değerlendirip sonuca bağlayan Bilim sekreterimiz Prof. Dr. Onur Çelik ve Bilimsel kurul üyelerine teşekkür ediyorum. Kongrenin teknik alt yapısını üstlenip, sekreteryasını yürüten Serenas firmasına, çalışanlarına ve özellikle yakın mesai yaptığımız Ferda Ümit Ar’a teşekkür ediyorum. Kongrenin gerçekleşmesinde önemli destekleri olan ve her zaman olduğu gibi sanal ortamda da yanımızda bulunan sponsor firmalara, onların nazik yöneticilerine verdikleri destek nedeniyle teşekkür ediyorum.Değerli kongre katılımcılarımız, Bu bilim şöleninde bizlerle birlikte olduğunuz için sizlere de teşekkür ediyorum. Tekrar hoş geldiniz diyor, kongrenin hepimiz için yararlı olmasını diliyorum. Saygılarımla

Prof. Dr. Fazıl Necdet Ardıç8.Ulusal Otoloji Nörotoloji Kongresi Başkanı

Dear Colleagues, On behalf of the organizing committee, I am honored and happy to welcome you to the 8th National Congress of Otology Neurotology organized by the Turkish Society of Otology Neurotology. I would like to begin my speech by respectfully commemorating our independent country, our founder Mustafa Kemal Atatürk, who paved the way for free thought that enabled us to become scientists, and his colleagues, and the pioneers of otolaryngology in our country. Although the virtual environment of our congress prevented meeting you face-to-face, sharing the joy of a successful congress and the joy of scientific challenge in the same room, it also opened different windows of opportunity.In this organization, we brought together a team that is very difficult to come together in a regular congress, in the same program. We brought together 42 scientists from different countries and 136 scientists from our country. We have an almost breathless program in 3 halls from 8:00 in the morning to 18:00 in the evening. The papers were evaluated by the international scientific comittee. We prepared the summary book and presentations in English. 75 papers were accepted to our congress. The reduction in costs also allowed us to reduce registration fees to levels that are affordable for everyone. The scientific level of this congress reflects the knowledge and dynamism of scientists working in the field of Otology Neurotology.At this opening ceremony after a busy period of work, I would like to continue with my thanks to the great team who contributed to the realization of the congress. I would like to thank our president of the association, Prof. Dr. Nuri Özgirgin, who contributed greatly to the scope and quality of our congress and whom I see with me in every problem, for his strong and unconditional support. I would like to thank the executive board of the Otology Neurotology Society, who expressed their trust in me and supported me in every way during the organization of this congress. I would like to thank our speakers, moderators and session chairmen, who accepted the tasks and organized quickly even though there was a very short time left. I would like to thank our Scientific Secretary Prof. Dr. Onur Çelik and the members of the Scientific Committee who evaluated and concluded the submitted papers in a timely manner.. I would like to thank Serenas firm and its employees who undertook the technical infrastructure of the congress and carried out its secretariat, and especially Ferda Ümit Ar, with whom we worked closely. I would like to thank the sponsor companies and their kind managers for their support in the realization of the congress.Dear congress participants,Thank you for being with us at this science fair. I welcome you again, I wish the congress to be beneficial for all of us.Best regards

Prof. Dr. Fazıl Necdet ArdıçPresident of the 8th National Otology Neurotology Congress

INVESTIGATION OF QUALITY OF LIVES OF IDIOPATHIC SUDDEN SEN-

SORINEURAL HEARING LOSS PATIENTS

Ahmet Mutlu1, Ayşe Yasemin Gündüz1, Burcu Bakıcı Balcı 1, Mahmut

Tayyar Kalcıoğlu1

Otorhinolaryngology

Objective: Idiopathic sudden sensorineural hearing loss (ISSNHL) may

affect quality of lives at different levels. Purpose of this study is to

measure how individuals were affected socially, psychologically and

mentally after they experienced ISSNHL.

Materials and Methods: This study was designed as a cross sectional

study with archive research and patients who were diagnosed as

ISSNHL between 2015 and 2020 were claimed. Patients were asked

to answer the SF-36 (Short Form 36) questionnaire form by tele con-

versation. According to pure tone audiometry tests performed after

treatment, patients were divided into 2 groups: ‘completely recov-

ered’ (<20 dB) and ‘partially recovered’ (thresholds remained >20

dB). Mean scores of SF-36 quality of life subcategories were analyzed

for each group. Statistical analysis between the mean scores of the 2

groups were performed by using independent sample T-test via SPSS.

Results: 48 (58.5%) male and 34 (41.5%) female patients were in-

cluded. As a result of analyses, there was significant difference in

physical functioning (p=0.046), vitality (p=0.05), and general health

scores (p=0.038) between 2 groups after ISSNHL treatment. Although

mean scores of the patients who were completely recovered

were higher, no significant difference was found in physical-role

(p=0.125), emotional-role (p>0.05), mental health (p>0.05), and bodi-

ly pain (p=0.48) subcategory scores between 2 groups.

Conclusion: The mean results of completely recovered patients in our

study clearly showed that a successful treatment and recovery pre-

vented all kinds of the disease’s potential physical and mental com-

plications. It is seen that the effects of the morbidity on the patient

begin to be felt with somewhat more serious problems in individuals

who cannot make a full recovery. Our findings showed that it could

be helpful to remark on changes in the quality of life of patients who

experienced ISSNHL and could be a guide for further studies.

AUTONOMOUS INNER EAR ACCESS IN ROBOT ASSISTED COCHLEAR

IMPLANT SURGERY (RACIS)

Vedat Topsakal1, Griet Mertens2, Vincent Van Rompaey2, Paul Van De

Heyning2

1Uz Brussel - Vrije Universiteit Brussel 2Uz Antwerp - University Of Antwerp

Objective: The HEARO® robotic system is an assistive otological next

generation surgical robot to assist the surgeon with cochlear implan-

tation (CI) surgery. It provides software-defined spatial boundaries

for orientation and reference information to anatomical structures

in order to execute drilling directly towards inner ear to facilitate a

keyhole access.

Materials and Methods: Here, we report the feasibility but also

safety and efficiency of this procedure for Robot assisted cochlear

implant surgery (RACIS) in the first 25 patients.All patients indicated

for cochlear implantation in a routine conventional work-up fulfilling

the audiological criteria were radiologically screened. Patients with

suitable anatomy were approached for participation with written in-

formed consent. This clinical trial was approved by the medical ethics

comity.

Results: Seven cases had not passed the radiological screening and

only one patient opted to have conventional CI surgery. The RACIS

was performed in 25 patients including 6 women (24%) and 19 men

(76%). The age values of 25 patients ranged from 20 to 89. Three pro-

cedures were converted to conventional surgery because of our safe-

ty protocols: mainly for the facial nerve during drilling of middle ear

access. In total 22 procedures were successfully drilled up to the level

of inner ear without any facial nerve injuries or any other adverse

events. From these 22 cases all patient had a full insertion of the

cochlear implant. In 1 case the post op image showed that the last

electrode was at the level of the round window. Although the patient

had auditory sensations with this electrode, it was the only electrode

that was switched off by the audiologist.

Conclusion: Specific cases with aberrant anatomy, surgical challenges

and anatomical accuracy will be discussed in the presentation. We

conclude that the HEARO procedure is safe and effective assistive tool

for a cochlear implant surgeon.

OP - 03THE EFFECT OF COVID-19 ON THE HEARING SYSTEMÖzge Gedik1, Hilal Hüsam1, Meliha Başöz1, Nida Tas1, Fadlullah Aksoy1

1Bezmialem Vakif UniversityObjective: This study aims to evaluate different auditory regions with audiological tests, based on the presumption that there may be dam-age to the structures in the hearing system after COVID-19.Materials and Methods: The control group consisted of 20 individuals (F/M: 17/3; mean age: 29.25 ± 7.62 years) with no history of COVID-19, and the study group consisted of 27 individuals diagnosed with COVID-19 by polymerase chain reaction test (F/M: 17/10; mean age: 32.5 ± 8.02 years). All participants were administered the pure tone, speech and extended high-frequency audiometry, acoustic immitansmetry, transient evoked and distortion product otoacoustic emission and auditory brainstem response tests.Results: According to the results of the pure tone audiometry, a significant difference was observed in the mean low, high and extended high-frequency thresholds, and the mean threshold values were higher in the study group. In the otoacoustic emission test, while the signal-to-ratio values were bilaterally and significantly lower at 4 kHz in transient evoked otoacoustic emission in individuals with a history of COVID-19, no significant difference was observed in the distortion product otoacoustic emissions. In the auditory brain-stem response test, no significant difference was observed in absolute wave I, III and V latencies, wave I and V amplitudes and the amplitude ratio of V/I.Conclusion: There is a possibility that COVID-19 could can cause damage to the hearing system, particularly in high frequencies. Additionally, audiological follow-up could be helpful to investigate the potential long term effects of SARS-CoV-2 on hearing in patients with a history of COVID-19. Further research is needed to determine the effect of COVID-19 on the auditory system.Keywords : Auditory Brainstem Responses, Hearing loss, SARS-CoV-2OP - 04INVESTIGATION OF THE EFFECT OF CARDIAC SURGERY ON HEARING FUNCTIONSAsuman Feda Bayrak1, Hasan İner2, Akif İşlek3

1Izmir Ataturk Training And Research Hospital 2Izmir Katip Celebi Univercity Ataturk Training And Research Hospital 3Nusaybin State HospitalObjective: Hearing loss conditions after open-heart surgery via extra-corporeal circulation is a rarely reported complication. Microembolic phenomena (oil, air or particle thrombus), perioperative hypotension or perfusion failure, hypercoagulation states, and ototoxic drug use are emphasized in the pathogenesis. The aim of the study is to com-pare the results of preoperative and postoperative pure tone audiom-etry measurements to determine possible hearing loss that may occur in patients who had open-heart surgery.Materials and Methods: Preoperative and postoperative audiometric measurements were performed in 21 patients who had open-heart surgery in the Izmir Ataturk Training and Research Hospital between July 2016 and May 2017. Pure tone audiometry test was performed at 0.25, 0.5, 1, 2, 4, 6, 8 KHz. Measurements were applied before the operation and after the general condition stabilization stage at post-operation. Patients over 40 years of age who could comply and were approved the test were included in the study. Those with a pre-vious history of ear disease were not included in the study.

Results: Twenty-one patients were included in the study. One of the patients was excluded from the study because of the post-operation death at the early stage. The mean age of 20 patients included in the analysis was found as 60.7 ± 7.7 (min: 46, max: 76). 4 (20%) of the patients were female and 16 (80%) of them were male. Mean values of preoperative pure tone (PTA) of the patients at 0.5, 1, 2, 4 KHz frequencies were calculated as 23.0 ± 11.0 dB for the right ear and 26.3 ± 13.0 dB for the left ear. Postoperative PTA values for all patients were 24.5 ± 7.7 dB for the right ear and 28.8 ± 15.0 dB for the left ear. (P = 0.728, 95% Cl: -6.8-4.8 dB and p = 0.614, 95% CI: -9.7-5.8, respec-tively). While post-operation PTA results of 5 patients’ (%25) right ear was 25dB and more, the patient number has increased to 8 (40%) (n=8) at the post-operation stage (p=0,375) McNemar Test). The num-ber of patients with PTA 25 dB and above in the left ear was found as 8 (40%) pre-operation stage and 12 (60%) post-operation stage (p = 0.219, McNemar Test). There is any other detected significant differ-ence in terms of hearing thresholds frequencies. Conclusion: In this study, no loss of hearing symptoms were ob-served. As a result, developing surgical techniques provide hemody-namic stabilization and do not impair neurocognitive functions.

1Yozgat City HosObjective: It was aimed to determine the hearing screening results of twin newborns and the factors affecting the screening.Materials and Methods: In this study, hearing screening test results of 73 twins, 146 newborns, born between 01.01.2017 and 31.12.2020 were discussed. The patients who failed this test were called for the test again within 1 month. Babies who failed this screening and those with risk factors for hearing loss were referred to a tertiary center. According to the arrival days of newborns for screening test, they were divided into 4 groups: first group, those who came in the first 10 days, the second group, those who came between 11-20 days, the third group, those who came between 21-30 days, and the fourth group, who were >30 days old.All screened patients were questioned in terms of delivery type (nor-mal delivery/cesarean section), birth weight, birth week, history of staying in the intensive care unit, and neonatal jaundice. SPSS statistic 22 program was used for statistical analysis. A p<0.05 was accepted as a significant difference.Results: Of the 146 newborns participating in the study, 71 (48.6%) were female and 75 (51.4%) were male. Of the newborns, 10 (6.8%) were born by normal delivery and 136 (93.2%) by cesarean section. In the first test performed in our clinic, 111 (76%) passed through both ears, 25 (17.1%) remained in both ears, 3 (2.1%) remained in the right ear only, 7 (4.8%) ‹ only the left ear remained. There were 68 (46.6%) newborns in the first group, 22 (15.1%) in the second group, 25 (17.1%) in the third group, and 31 (21.2%) in the fourth group in the twins grouped according to the days of admission to the screening test. While there was a history of staying in the intensive care unit in 69 (47.3%) newborns, it was absent in 77 (52.7%). 38 (26%) of these patients were treated for icterus. While the mean birth weight of the newborns participating in the study was 2474.08±436.38, the mean week of birth was 35.68±1.9. There was a statistically significant difference between the groups when the newborns were grouped

according to the days of their arrival for the screening test (p=0.002).Conclusion: This study reflects the results of twins living in Yozgat who came to our clinic for newborn hearing screening test. The rate of first test failure is higher with twin newborns arriving within the first 10 days after birth. More work needs to be done for this.Keywords : Hearing Tests, Newborn, TwinsOP - 06EVALUATION OF TINNITUS IN POST-COVID-19 CASESSermin Can1, Hasan Mensur Ekinci1, Günay Kozan1

1University Of Health Sciences, Gazi Yasargil Education And Research Hospital Department Of Otorhinolaryngology And Head And Neck Surgery, Diyarbakir, TurkeyObjective: We aimed to evaluate patients who developed subjective tinnitus complaints after COVID-19 infection with Tinnitus Severity Index (TSI) and to discuss the results.Materials and Methods: A total of 20 patients between the ages of 18-50 who did not have any otological disease and had no chronic disease before applied to our outpatient clinic with subjective tinnitus complaints after COVID-19 infection and tinnitus was evaluated with TSI. The total symptom score (TSS) of the patients was calculated and graded as very mild, mild, moderate, severe and very severe. Statis-tical analysis was done with SPSS 20. Independent sample T test and Pearson correlation tests were used. Otoscopic examinations of these patients were normal, and their hearing values were found to be in the range of 0-25 dB in pure tone audiometry.Results: The mean age of 20 patients, consisting of 10 male and 10 female patients, was 29.5±10.6 years. The total symptom score (TSS) of the patients was a minimum of 31, a maximum of 47, and a mean of 39. Tinnitus was severe in 12 patients and moderate in 8 patients. There was no statistically significant difference between men and women in terms of mean TSS (p>0.05). In addition, there was no sig-nificant difference between age and mean TSS (p>0.05).Conclusion: Moderate or severe subjective tinnitus, which affects the quality of life of patients, may occur after COVID-19 infection, regardless of age and gender.Keywords : COVID-19, tinnitus, quality of lifeOP - 07VİTAMİN B12 AND FOLATE LEVELS İN PATIENTS WİTH TINNITUSAyşe Çeçen1, Asude Ünal1

1Samsun Training And Research HospitalObjective: True tinnitus is a phantom auditory perception arising from a source or trigger in the cochlea, brainstem, or at higher centers and has no detectable acoustic generator. The objective was to test the hypothesis that tinnitus may be associated with poor vitamin B-12 and folate status.Material and Methods: This retrospective study, plasma levels of folate and vitamin B12 were determined by comparing subjects with and without tinnitus between 2019 and 2020, in Samsun Training and Research Hospital, Department of Ear Nose. The study group included of 75 patients, aged 20-70 years, who with the complaint of tinnitus for at least 6 months. The control group included of 40 patients who did not have ear pathology, who applied to our polyclinic with other complaints, and who had vitamin B12 and folic acid values in routine blood tests. A typical otological and audiological examination was car-ried out in all patients. Computed tomography (CT) and/or magnetic resonance imaging (MRI) was examined when retrocochlear hearing loss is suspected. Patients whose blood serum vitamin B12 levels

were below 180 pg/mL were deemed to be vitamin B12-deficient.Results: Mean age and gender was the same for the study and control groups. Comparing the plasma levels of the markers between study and control group, the plasma levels of folate (p=0.01) and vitamin B12 (p=0.03) were significantly lower among the with tinnitus com-pared to healty.Conclusion: Poor vitamin B-12 and folate status may be associated with tinnitus. The widely-varying aetiology of tinnitus indicates that more studies are needed to find causes of and effective treatments for tinnitus.Keywords : vitamin B-12, folate, tinnitusOP - 08SERUM FERRITIN, VITAMİN B12 AND FOLATE LEVELS IN PATIENTS WITH TINNITUSEmine Ceren Ersöz Ünlü1, Ceren Karaçaylı2

Serum ferritin, vitamin B12 and folate levels and, also pure tone audiometry results were obtained from the hospital’s database. Serum ferritin, vitamin B12 and folate levels, pure tone averages and 6kHz hearing levels were evaluated. Pure tone averages were calculated by the average of four frequencies (500Hz, 1000Hz, 2kHz and 4kHz).Results: The mean age of the patients was 48.18±16.19 years. Serum ferritin level was found to be low in 39.3% of the patients (n=35). The mean age of the patients with low serum ferritin levels was found to be significantly lower than those with normal serum ferritin levels (p = 0.042). A moderate positive correlation was found between age and pure tone average (right; p<0.001, ρ=0.388, left; p<0.001, ρ=0.396) and, also between age and 6kHz pure tone threshold (right; p<0.001, ρ=0.694, left; p<0.001, ρ=0.668).Conclusion: Although various otologic and non-otologic causes are shown to be in tinnitus etiology, in many patients, the underlying cause cannot be identified. One of the causes of tinnitus is iron defi-ciency, which was found low in 39.3% of our patients. The other most common cause of tinnitus is presbycusis which is age-related. The lower mean age in patients with low serum ferritin level and the posi-tive correlation with age and hearing loss may suggest that low serum ferritin level is an important factor in the etiology of tinnitus in the absence of presbycusis.Keywords : tinnitus; ferritin; vitamin B12; folateOP - 09COMPLICATIONS OF OTITIS MEDIA: 11 YEARS OF EXPERIENCEYüksel Olgun1, Enver Can Öncül1, Özgür Kümüş2, Fatih Yunus Emre1, Enis Alpin Güneri1

1Dokuz Eylül University Faculty Of Medicine Department Of Otorhino-laryngology 2Muş Medical Center HospitalObjective: Aim of this study is to present the clinics and treatment in-formations of patients presented with otitis media (OM) complications.


Materials and Methods: Patients who were followed up, treated for OM in Dokuz Eylul University Department of Otorhinolaryngology between January 2009 and October 2020 were included in the study. Patients’ demographics, findings at the time of admission, radiologi-cal examinations, treatment approaches and follow-up periods were evaluated retrospectively.Results: Thirty-seven patients, 24 of whom were treated for compli-cations due to chronic otitis media with cholesteatomas (COM) and 13 due to acute otitis media (AOM) were included in the study. A total of 28 complications were encountered in COM patients. Of these complications 25 were extracranial and 3 were intracranial. Extracra-nial complications consisted of 13 lateral semicircular canal fistulas (LSCCD), 9 peripheral facial paralysis (PFP), 2 subperiosteal abscess, and one Citelli abscess. There were 2 temporal lobe abscesses and one sigmoid sinus thrombosis as intracranial complication. More than one complication was observed in 4 patients. Two patients who were treated for temporal lobe abscess were approached jointly with the neurosurgery department, radical mastoidectomy and intracranial abscess drainage were performed. In 13 patients with LSCCD, after appopriate removal of the cholesteatoma and the fistula was repaired with bone pates and soft tissues. We were able to preserve the hear-ing in all of these patients. In 9 patients with facial paralysis whom were operated a complete recovery was observed in 6 patients, while grade 2 PFP was observed in the last follow-up in 2 patients. One patient has lost to follow after the first month of the operation. Mod-ified radical mastoidectomy and medical treatment were applied to the patient with sigmoid sinus thrombosis, and it was observed that the thrombosed segment in the sinus was re-canalised at the 2nd-month controls.We have treated 14 AOM complications in 13 patients. Extracranial complications consisted of 5 subperiosteal abscesses, 3 peripheral facial paralysis, 2 mastoiditis, 2 labyrinthitis. As intracranial compli-cations, epidural abscess and sigmoid sinus thrombosis were seen in one patient. In addition to intravenous antibiotherapy, abscess drainage was performed for all patients with subperiosteal abscess. Patients with facial paralysis and labyrinthitis were treated with ven-tilation tubes and antibiotics and oral steroids were also given for the patients with labyrinthitis. Intravenous antibiotherapy, abscess drainage, mastoidectomy, and anticoagulant therapy were applied to the patient who presented with epidural abscess and sigmoid sinus trombosis. All patients recovered without any sequelae.Conclusion: Although complications due to OM are not common, early diagnosis and appropriate treatment are crucial to prevent mor-bidities and mortalities.Keywords : otitis media, complication, peripheral facial paralysis, lat-eral semicircular canal fistulas, subperiosteal abscess, Citelli abscess, sigmoid sinus thrombosisOP - 10THE NEUTROPHIL-TO-LYMPHOCYTE RATIO CORRELATES WITH THE MIDDLE EAR RISK INDEX IN CHRONIC OTITIS MEDIA PATIENTS.Akif İşlek1

1Nusaybin State HospitalObjective: This study aimed to investigate the neutrophil-to-lympho-cyte ratio and severity of the chronic otitis media according to middle ear risk index (MERI) scores.Materials and Methods: The neutrophil-to-lymphocyte ratio (NLR) and middle ear risk index calculated for 210 Chronic otitis media (COM) patients retrospectively. NLR compared between COM

patients and 159 healthy participants. Pearson correlation analysis was performed for NLR and MERI. In addition, The cut-off value, sen-sitivity, and specificity for NLR were determined in COM according to the severity of the disease with ROC analysis.Results: The average of NLR in all patients was 1.94 ± 0.89. NLR was calculated as 2.05 ± 1.03 in the patients with COM and 1.79 ± 0.64 in the control group (p=0.006, 95% CI: 0.07-0.44, t-test). According to the ROC analysis, the cut-off point was determined as 1.95 for moderate and severe disease in MERI. For the cut of an NLR=1.95, sensitivity was calculated as 48.5 % and the specificity 57.1 % for moderate and severe COM. MERI score was found significantly higher in patients with postoperative graft perforation (p< 0.001, 95%CI=0.7-1.8). NLR has not related significantly with the MERI score according to linear regression analysis (p = 0.927)Conclusion: NLR was found to be significantly higher in chronic otitis media patients compared to the control group. But NLR was not re-lated to the severity of the disease classified with MERI. The cut-off value, sensitivity, and sensitivity rates of NLR obtained were not avail-able for clinical use.Keywords : Neutrophil-to-lymphocyte ratio; Middle ear risk index; Chronic otitis media; TympanoplastyOP - 11INVESTIGATION OF THE PRESENCE OF CORONAVIRUS AND VARI-ANTS IN CERUMEN OF PATIENTS WITH COVID-19 DIAGNOSISEyyup Kara1, Sinem Kara2, Ebru Karaman1, Halide Çetin Kara2, Deniz Gözen Tan1, Mert Kuşkucu3, Melda Acar1, Yeşim Tok3, Ahmet Ataş2

1Istanbul University-cerrahpaşa, Faculty Of Health Sciences, Audiology Dept. 2Istanbul University-cerrahpaşa, Medical Faculty, Ent Dept. 3Istanbul University-cerrahpaşa, Medical Faculty, Medical Microbiolo-gy Dept.Objective: In December 2019, a new and contagious, atypical (viral) pneumonia case was reported in Wuhan, China. On January 7, 2020, the agent was identified as a new coronavirus (2019- nCoV) that has not been detected in humans before. Later, the name of the 2019-nCoV disease was accepted as COVID-19, the virus was named as SARS-CoV-2 due to its close resemblance to SARS CoV. As a result of the presence of virus in the ear fluids (Cerumen), the risk of virus transmission to both the practicing personnel and other patients will increase rapidly. Therefore, the presence of coronavirus in the ceru-men is of great importance. The aim of our study is to investigate the presence of coronavirus in the ear fluids/cerumen of patients diag-nosed with Covid-19.Materials and Methods: A total of 50 patients diagnosed with Covid-19, including 30 men and 20 women, were included in the study. Results: SARS-CoV-2 RNA was positive in only one (2%) of the external ear canal samples of 50 patients diagnosed with COVID-19 (E gene Ct: 30.28, RdRP gene Ct: 32.82, N gene Ct: 31.38). In the variant screen-ing, 69-70 deletion and ORF 1a deletion were detected in the sample, while 242-244 deletion and E484K mutation were not observed. Ac-cordingly, the patient sample was evaluated as SARS-CoV-2 UK variant (B.1.1.7-GR/501Y.V1). The UK variant was detected in 9 of 50 patients with a positive PCR test.Conclusion: Audiological equipment and hearing aids are in constant contact with cerumen, and people who come into contact with them are also at risk for infections that can be transmitted from cerumen. The risk of covid19 virus in cerumen will play a role in protecting

audiologists and other health professionals from contamination and taking precautions. Our study also reveals the risk of transmission in different variants by studying the issue of virus variants, which are not included in other studies. The presence of British variant virus in-ear swabs in only one female subject out of 50 suggests that it is important to routinely screen for the risk of transmission in different body fluids and cerumen as changes in variants are observed. In ad-dition, since only one female subject was positive in our series, it was thought that it would be important to investigate the risk of Covid-19 transmission in cerumen in order to reveal the risk based on gender in a larger population.Keywords : Covid-19, Cerumen, Covid19 variants, audiological equip-ments, infectionOP - 12A NEW MARKER IN INFLAMMATORY ETIOPATHOGENESIS OF BELL’S PALSY: IMMATURE GRANULOCYTEAyhan Kars1, Sedat Gulten2, Fatma Atalay1, Kubra Topal1

1Kastamonu University Faculty Of Medicine, Department Of Otorhino-laryngology, Head And Neck Surgery 2Kastamonu University Faculty Of Medicine, Department Of Medical BiochemistryObjective: Bell’s palsy (BP) pathogenesis is not fully understood, but is generally idiopathic. Studies investigating the etiopathogenesis of BP suggest have implicated factors such as inflammation, viral infection, microvascular dysfunction, and exposure to acute cold. The purpose of this study was to reveal the effectiveness of immature granulocyte (IG) as an inflammatory marker in the etiopathogenesis of BP.Materials and Methods: The retrospective study was performed Sep-tember 2019 and January 2021. Thirty-three patients presenting to the our Ear, Nose, and Throat Clinic diagnosed with BP were included in the study. A control group consisting of 50 individuals with similar age and gender distributions to the patient group and presenting for routine examinations was also established. Immature granulocyte count (IGC), and immature granulocyte percentage (IG%) values were calculated from complete blood count (CBC) data.Results: No significant difference was determined between the two groups in terms of age or gender (p<0.05). IGC values found to differ significantly between the patient and control groups (p=0.004). No significant differences were observed in the IG% (p=0.061).Conclusion: Although the etiopathogenesis is not yet fully understood, viral, inflammatory, and immune system mechanisms play the most important role in the etiopathogenesis of BP. Edema developing in association with inflammation secondary to viral infections can also easily damage the facial nerve, with its anatomically narrow canal. The fact that BP generally resolves completely suggests a close association with inflammation and edema. Technical improvements in automated hematology analyzers in recent years have made it possible to determine IG percentages and counts. Various studies have shown that IG can be used as an effective inflammatory marker. To the best of our knowledge, no studies have investigated increases in IGC in BP.Inflammation is one of the main theories in the context of BP. Higher IGC being determined in patients with BP compared to the healthy control group supports the idea of the role of inflammation in the etiopathogenesis.Keywords : Bell’s palsy; immature granulocyte; inflammation.

1Tepecik Training And Research HospitalObjective: Paraganglioma is the most commonly diagnosed neuro-tologic neoplasm after acoustic neuroma. They are histologically be-nign, but they are considered clinically malignant because they hold important neurovascular structures and show intracranial spread. However, malignant transformation and metastasis have also been reported.1,2.In addition, they can cause life-threatening hypertension crisis with catecholamine secretion during surgical manipulation.3.Oc-curring more commonly in caucasians the female to male ratio is 5:1.4,5.Paragangliomas have been reported in all age groups but most frequently occur in the fifth and sixth decades of life. They are usually solitary. A hereditary tendency with an autosomal dominant mode of inheritance has been identified.6,7.For familial tumors, the incidence of multiple paragangliomas is 25% to 50%.6,7,8.The ideal management of most paragangliomas is complete surgical excision. Materials and Methods: Nine cases diagnosed as glomus tympan-icum and jugulare tumors by our team between 2016-2021 were included in our study.Results: Seven of the 9 patients with glomus tumors were female and two were male.(Table 1).Their age ranged from 36 to 82, with an aver-age age of 59.4.Among the 9 patients there were 7 glomus tympani-cum, 1 glomus jugulare and 1 glomus jugulotympanicum. Of these, 7 tumors underwent surgery.One patient did not accept the operation.One patient applied to another center and embolization and radio-therapy were performed there.No residual or recurrence was detect-ed in the control imaging.The operated patients were evaluated with preoperative CT, MRI and angiography. The tumor could be removed completely in 6 patients .In particular, complete resection of glomus tympanicum was achieved in 100%.In the glomus jugulotympanicum patient,House Brackmann Stage 4 facial paralysis and otorrhea devel-oped in the postoperative period.In a patient with glomus jugulare, the tumor started from the right jugular fossa and extended super-omedially to the cerebellopontine corner, and complete resection could not be achieved.The patient with glomus jugulare was followed in the neurosurgery department in the postoperative period and did not apply to our clinic.All 5 cases with glomus tympanicum were op-erated transmeatally using the retroauricular approach.The patient with glomus jugulotympanicum was operated with the infratemporal fossa type a approach.The patient with glomus jugulare was operated with a combined approach to the neck and skull base.Conclusion:Although recently developed skull base surgery, interdis-ciplinary efforts, new imaging techniques and appropriate anesthesia have achieved a high incidence of recovery in glomus tumors, surgical treatment also brings many risk factors. Undoubtedly, the risk of mor-bidity in glomus tumor surgery is related to the size of the tumor.Keywords : Glomus Tumor Glomus Tympanicum Glomus Jugulare

111 Minsk City Clinical Hospital (Minsk, Belarus) 2Belarusian Medical Academy Of Postgraduate Education (Minsk, Belarus)Objective: The number of otitis media with effusion (OME) has in-creased in 2.5 times among the non-purulent diseases of the middle ear over the past 20 years. OME is a multifactorial disease, often result-ing from the combination of several causal factors. The most significant risk factors in the comparative analysis of adult patients with acute and chronic OME are inflammatory diseases of the paranasal sinuses (PS), the nasal septum deviation was observed in 55% of the patient’s cases with OME. Our aim is to analyse the risk factors for developing effusion in the tympanic cavity in adults.Materials and Methods: Fifty-one patients aged 18-70 years who had been treated for OME in the ENT-department of the 11 Minsk City Clinical Hospital and the Gomel Regional Clinical Hospital were examined during the 2018-2020 year. Patients were examined according to the guidelines of the patients’ examination and treatment with OME. Statistical analysis of the results was performed by using non-parametric statistical processing methods. In all statistical analyses was the achieved significance level (p) calculated, herewith in our study the critical significance level was taken to be 0.05.Results: In the presence of acute OME, significantly prevailed patients of the age group 31-40 year, with the chronic form predominated people of the 51-60 year, and in all analyzed groups women dominated. The nasal septum deviation was observed in 55% of the patient’s cases with OME. In 81% chronic inflammation of PS pre-vails in the chronic form of OME. Patients with acute OME acute and chronic inflammation of PS was equally often occurred in 54.5% and 45.5%, respectively. The bilateral process of the forming the effusion in the tympanic cavity is the most common for the chronic form of OME. According to the statistic women more often suffer from OME.Conclusion: Patients with inflammatory diseases of the nose and PS are at risk of developing OME and are required dynamic audiological examination. According to the research, was reliably proved that smoking and rural or urban residence is not a risk factor for the forma-tion of tympanic effusion.Keywords: Risk factors, OME, pathology of the nose and paranasal sinuses.

For each patient, age, gender, COVID-19 combined mouth and nose swab test result, facial paralysis House-Brackmann(HB) staging and side, audiogram infor-mation, treatment applied to the patient, the recovery time of the patients, comorbidities, and additional symptoms to facial paralysis were collected.Results: 58 patients were followed up during the pandemic period and 45 patients in the 1 year before the pandemic. During the pandemic period, 5 (8.6%) of the patients with acute peripheral facial paralysis were evaluated as COVID-19 positive and 3 (5.1%) were considered as contacts. No statistically significant difference was observed between the parameters compared between group 1 and group 2. When the patients in both group 1 and group 2 were examined, the treatment responses were statistically significant according to the first and last House-Brackman (HB) staging (p<0.001).Conclusions: In statistical comparisons between the pandemic period and the previous 1 year; there was no statistically significant difference between the two groups in terms of the parameters evaluated and the responses to treatment. The relationship between patients with acute peripheral facial paralysis and COVID-19 during the pandemic period is coincidental.Keywords : Coronavirus, Bell palsy, facial nerve

1Kütahya Health Science University, Evliya Çelebi Research And Train-ing HospitalObjective: We aimed to conduct a descriptive bibliometric research, in which the quantitative analysis of otology-neurootology books in Turkey between 1892-2021 was carried out.Materials and Methods: The National library explorer automation system, the database available on the official website of the electronic booksellers and publishing houses selling books in Turkey, and the Turkish Otorhinolaryngology Bibliography book were used to determine the books published between 1892 and 2021 in the field of otology-neurotology. The year and the city in which the books were published, the evaluation of the subject, the features of translation and copyrighted works were evaluated.Results: It was shown that the number of books found in the field of otology-neurootology between 1892 and 2021 was 43. It has been determined that the first otology book identified was translated by Mehmet Neşet in 1892 and published in Istanbul. It has been detect-ed that the most up-to-date book in our research was published in Ankara in 2021 on audiology as a copyrighted work by Fuat Bulut. It was observed that the city in which the books were published the most was Istanbul (19), followed by Ankara (13) and seven of the books were translated works and thirty-six were copyright. In the evaluation of the publication date, 8 books were published in the 1892-1940 time period, 11 books in the 1940-1980 time period and 22 books in the 1980-2020 time period. In the last 10 years, it has been observed that 18 books have been published in the field of otol-ogy-neurootology.Conclusion: It was pleasing to see the quantitatively increasing number of books in the field of otology-neurotology and the diversity of topics in the books.

1Fatih Sultan Mehmet Training And Research HospitalObjective: Bell’s palsy(BP) is an idiopathic,acute,paresis or paralysis of the face in a pattern consistent with peripheral facial nerve dys-function,without any detectable cause.The exact cause of BP is still uncertain.The aim of this study is to reveal the pathologies that may predispose to BP.Materials and Methods: Our study is a retrospective study.The study group of patients who were hospitalized for BP in the tertiary care reference hospital ear nose and throat clinic between January 2019 and October 2020; People who are at the same age as the study group and have similar comorbidities constitute the control group.The patient records of the two groups in the hospital information system were scanned retrospectively,by age,gender,hemoglobin,RDW(Red Cell Distribution Width),NLR(Neutrophil-Lymphocyte Ratio),ferrit-in,iron binding capacity (UIBC),iron,vitamin D,vitamin B12,folate levels were recorded and compared statistically.In addition, the degree of facial paralysis, the side of facial paralysis, and the degree of vitamin D deficiency in the patient group;and the relationship between other studied parameters were investigated.Results: There was no statistically significant difference between the

groups in terms of mean age and gender distribution(p>0.05).The NLR and ferritin levels of the patient group were statistically signifi-cantly higher than the control group(p <0.05).Vitamin D levels of the patient group were statistically significantly lower than the control group (p<0.05).A statistically significant positive correlation between the degree of facial paralysis and folate level(p<0.05).There was no statistically significant difference was found in terms of other study parameters(p>0.05).Conclusion: The NLR and ferritin levels were significantly higher in patients with BP. NLR and ferritin can be used as auxiliary parameters in the diagnosis of Bell’s palsy.A positive and significant relationship was found between the degree of facial paralysis and the folate level.Vitamin D level in the patient group was found to be lower than the control group. As far as we know, there is no study in the literature examining the relationship between Bell’s palsy and folate and vita-min D levels.Further studies with larger patient groups are needed to determine the etiology of Bell’s palsy and contribute to its treatment.Keywords : Bell’s palsy, vitamin D, folateOP - 19EAR, NOSE AND THROAT SPECIALISTS’ PERSPECTIVE ON OTOLO-GY-NEUROTOLOGYOnur Erdoğan1

1Olbamed HospitalObjective: To investigate the rate of preference of otology-neurolo-tology among ENT sub-branches of ENT specialists in Turkey. To get an idea about the present and future of otology-neurotology in our country by revealing the reasons for choosing this most preferred branch.Materials and Methods: 16 multiple-choice questions were directed to ENT specialists via social media, sms and whatsapp applications. Physicians whose approvals were obtained online filled the question-naire. Responses were recorded and analyzed.Results: A total of 107 ENT specialists filled our questionnaire without any appendix. 34.3% of our colleagues were ENT specialists of 1-5 years. In addition, 34.3% of them were between the ages of 31-35. 70.4% consisted of men. It consisted mostly of people who had spe-cialized training at a state university. As a result of our survey, we saw that facial plastic surgery was the most preferred sub-branch with 30.6%. Otology-neurotology was in the second place with 26.9%. The most important factor in preference was professional satisfaction. The most important reason for not choosing the field of otology-neu-rootology was that it was a complex and tiring field. While the major-ity of our colleagues felt that they needed to improve themselves in the field of otology, the majority of them needed additional training after specialization training. Most physicians participating in the study were physicians who performed otologic surgery almost every week. Another remarkable point in our study was the sub-topic they would recommend to the resident physicians. 41.5% of the participants were recommending facial plastic surgery to our colleagues. Otology, on the other hand, was in the second place with 21.7%.Conclusion: Otology-neurorootology, which is one of the important branches of otolaryngology, is in the second place among the fields of interest of ENT specialists. Although we have recently seen facial plas-tic surgery procedures as the first or most important area of interest among our colleagues, otology-neurotology still maintains its popular-ity. However, the fact that even physicians interested in otology-neu-rotology recommend facial plastic surgery to our young colleagues suggests that there will be a much more decrease in the number of primary care physicians in otology-neurotology in the future.Keywords: Otology-neurotology, fellowship, perspectıve ENT


OP - 20EFFECT OF EXTERNAL EAR CANAL WALL ON FUNCTIONAL OUT-COMES OF OSSICULAR RECONSTRUCTION WITH TITANIUM TORPMustafa Koray Balcı1, Haydar Kazım Önal1

1İzmir Katip Çelebi University Ataturk Training And Research HospitalObjective: To investigate the effect of external ear canal wall on func-tional outcomes of ossicular reconstruction procedures with titanium total ossicular replacement prosthesis (TORP).Materials and Methods: Patients who underwent middle ear surgery and ossicular reconstruction with TORP in a tertiary referral center be-tween 2007-2014 were retrospectively searched in two groups; Canal Wall Up (CWU) + TORP and Canal Wall Down (CWD) + TORP. A total number of 93 cases were evaluated. Patients who were not under regular follow-up, patients with perforated grafts and/or pros-thesis extrusion, and patients who had other middle ear pathologies that may cause conductive hearing loss (otosclerosis, tympanosclero-sis, or fixed footplate) were not included in the study; as these pathol-ogies could cause additional hearing loss and complicate the analysis regarding the effect of ECW. Titanium TORP was used for ossiculoplasty in all procedures and con-chal cartilage was used as a graft. All patients in the study group had a minimum one year of follow up. Functional results were compared between two groups with pure-tone average (PTA), air-bone gap (ABG) at 4 frequencies (0.5, 1, 2, and 4kHz), increase in pure-tone average, and closure in ABG values.Results: CWU group included 30, CWD group included 36 patients who met inclusion criteria. In the CWU group, the mean pre-operative PTA was 55.7 ±14.7 dB; postoperative PTA was 42.5 ±16.9 dB, the mean increase was 13.2 ±13.6 dB. In the CWD group, mean preoperative PTA was 56.6 ±15.3 dB, postoperative PTA was 50.6 ±21.3 dB, the mean increase was 6.0 ±15.6 dB. The mean air-bone gap (ABG) closure val-ue was 15.8±10.7 dB in the CWU group and 6.4 ±10.5 dB in the CWD group. There was a significant difference in terms of PTA increase and ABG closure values between the two groups. Patients with post-oper-ative ABG < 20 dB were defined as successful with regards to previous studies. In CWU group 12 patients out of 30 (40.0%), in CWD group 10 patients out of 36 (27.7%) had postoperative ABG < 20 dB.Conclusion: The external ear canal wall has a positive effect on post-operative hearing when an ossiculoplasty with Titanium TORP is per-formed. The removal of ECW leads to a hearing loss of about 7dB in PTA levels and 9dB in ABG closure values in these cases.

1Department Of Otorhinolaryngology, Sakarya University Faculty Of Medicine, Sakarya, Turkey 2Department Of Otorhinolaryngology, Sakarya University Faculty Of Medicine, Sakarya, TurkeyObjective: Post operative adhesion is an important complication after middle ear surgeries. Although many materials have been tried to prevent this complication, the use of vivosorb (Vv) as an anti-adhesive material after middle ear surgery has not yet been reported. The aim

of this study was to evaluate the anti-adhesive effect of Vv on the ears of rats with middle ear mucosa damage. Materials and Methods: In our study, 14 Wistar albino rats and 28 ears in total were used. The rats were randomly divided into four groups. Middle ear mucosa damage was performed in all groups with a transcanal approach under otomicroscopy in sterile conditions. The effects of vivosorb, silicone silastic sheet (silastic®) and spongostan (Gelfoam®) were compared histologically with the secondary healing group. In addition, hearing evaluation was performed before the procedure and on the 28th postoperative day. Results: No significant difference was observed in transient otoacoustic emission and distortion product otoacoustic emissions tests performed before and after the surgical procedure when the groups were compared. While adhesion was observed in the tympanic membrane in the spongostan group, no adhesion was ob-served in the other groups. In the spongostan group, increased fibro-blastic activity, inflammation and neovascularization were observed in the middle ear mucosa. No significant difference was observed in silastic, vivosorb and control groups in terms of fibroblastic activity, inflammation and neovascularization. Conclusion: This study showed that vivosorb has no ototoxic effects, is biocompatible and can be used as an ideal absorbable support material to prevent adhesion in the middle ear.Keywords : Adhesion, Middle Ear, Inflammation, Healing, HistologyOP - 22ENDOSCOPIC TRANSCANAL TYPE 1 TYMPANOPLASTYAhmet Doblan1

1Reyap Istanbul HospitalObjective: To reveal the success and advantages of endoscopic tran-scanal type 1 tympanoplasty without flap elevation.Materials and Methods: The data of 132 who underwent endoscopic transcanal type 1 tympanoplasty at Mehmet Akif İnan Training and Research Hospital between January 2016 and July 2020 patients were evaluated retrospectively. Preop CT and audiogram were seen for each patient. All patients who underwent endoscopic transcanal type 1 tympanoplasty regardless of perforation size were included in the study.Surgical technique: The tympanic membrane was reached from the external auditory canal with a 0 and 30 degree endoscope. Middle ear mucosa and tympanic membrane were evaluated first. In each patient, the supratubal recess ossicular chain hypotympanum was directly seen with a 30 degree endoscope. With the malleus move-ment, the conduction of the movement along the ossicular chain is observed, and it was confirmed that the movement was transmitted through the round window.Results: In the preoperative audiograms of the patients, the mean air-bone gap was 19.3 db, and the postoperative mean air-bone gap was 8.5 db. Anterior opening of the graft was observed in two patients out of 14 preoperative total perforation patients, and medialization was observed in 3 patients, although the graft was intact. Graft success rate was determined as 96.21%.The average operation time of 132 pa-tients was 26 minutes, with the shortest 14 minutes and the longest 85 minutes (longer cases were patients with ossicular chain and cho-lesteatoma problems). All patients were operated , with perforation sizes ranging from 3 mm to total perforation. Average follow-up time (shortest 4 months, longest 48 months) average 25.4 monthsConclusion: Technical advantages, 1- All the advantages of endoscopic ear surgery are used, 2- It is an ideal technique for local application

in all perforation sizes (minimal or total perforation), 3- Since the vascular strip is not damaged, it has very fast recovery times, 4- Since it does not require dressing, it is easy to follow, 5- Since no incision is made in the external ear canal endoscopically, it is an almost com-pletely bloodless operation. The bleeding during the entire operation is less than 1cc ,6- Since there is no bleeding, the mucosa and ana-tomical structures can be seen in their natural colors, 7- The area cut for the graft is about 1 cm and does not cause any cosmetic problems. Endoscopic transcanal type 1 tympanoplasty graft success is accept-able. The fact that the flap is not elevated in the operation performed for this purpose accelerates the recovery. We think that it is a very successful and reliable technique functionally and anatomically.Keywords: Endoscopic tympanoplasty, tympanic membrane, inlay cartilage, cartilage tympanoplasty, chronic otitis media.OP - 23EVALUATION OF PATIENTS WHO UNDERWENT MYRINGOPLASTY SURGERY WITH THE HELP OF THE COVID-19 QUALITY OF LIFE IM-PACT SCALEGökhan Akgül1

1Department Of Otorhinolaryngology, University Of Health Sciences, Samsun Health Practices And Research Center, Samsun, TurkeyObjective: It is known that patients experience anxiety, fear and have difficulties in making decisions during the Covid-19 pandemic process. Due to these concerns of the patients, the quality of life may be neg-atively affected. We aimed to evaluate the effect of Covid-19 on the quality of life of patients who underwent type 1 myringoplasty during the Covid-19 pandemic period.Materials and Methods: The study group included patients with dry and uncomplicated chronic otitis media with hearing impairment due to tympanic membrane perforation between 2020 and 2021. The patients were divided into two groups. The patients in the first group consisted of those who did not want to postpone their surgery, even though they knew that their surgery was not urgent, and had surgery (Category D: Operations that improve quality of life, non-emergency or functional gain. May be delayed until one year later). The control group consisted of patients who had similar complaints with the first group, who were recommended to be operated on and who stated that the operation was not urgent, and whose operation time was delayed by the joint decision of the patient and the physician. Both groups were asked to fill out the questionnaire on the impact of Covid-19 on the quality of life. The Covid 19 quality of life scale consists of six items presented as a 5-point Likert scale that covers the basic quality of life areas related to mental health. The higher the score, the greater the impact of the pandemic on the person’s quality of life.Results: Forty-five people were included in this retrospective study. The patient group consisted of 21 patients who had type 1 myringo-plasty surgery and 24 patients in the control group whose surgery was postponed. No statistically significant difference was found between the groups in terms of age and gender. When the Covid 19 quality of life scale parameters of the patient group and control group were compared, no statistically significant difference was found between the groups. PConclusion: The COV19 quality of life scale is a reliable and valid scale that has the potential to facilitate both clinical studies and research on the impact of current and future pandemics on humans.Keywords: Covid 19, anxiety, myringoplasty

OP - 24THE EFFICACY OF BALLOON EUSTACHIAN TUBOPLASTY FOR EUSTA-CHIAN TUBE DYSFUNCTIONErdal Sakallı1

1Istanbul Aydin University Medical Faculty, Istanbul, TurkeyObjective: Eustachian tube (ET) dysfunction is a common clinical problem, but its treatment is still controversial [1]. Balloon dilation is one of the treatment procedure for obstructive dysfunction of the ET [2,3]. In this study, we aimed to assess the efficacy and safety of bal-loon dilation for ET dysfunction.Materials and Methods: The study was conducted on 9 adult pa-tients (15 ears) who had undergone previous unsuccessful medical treatment for ET dysfunction over two years. Tympanometry was the primary outcome measure. Secondary outcome measures included pure tone audiogram assessment and seven-item Eustachian Tube Dysfunction Questionnaire score. Outcomes were recorded pre-oper-atively and 3 months post-operatively to determine surgical success.Results: Of the 9 patients included in the study, 5 (55.5 %) were fe-male and 4 (44.5 %) were male. The mean age was 38.9 ± 10.5 years. Nine ears (60 %) in 5 patients with a type B or C tympanogram pre-op-eratively, had a type A tympanogram post-operatively. Ten ears (66.6 %) in 6 patients with pre-operative conductive hearing loss showed improvement post-operatively. Six (66.6 %) of the 9 patients demon-strated symptom resolution after ET balloon tuboplasty according to the seven-item Eustachian Tube Dysfunction Questionnaire. No com-plications were observed in any patients during procedure.Conclusion: ET balloon tuboplasty resulted in satisfactory improve-ment of subjective symptoms and objective evaluation of ET functions in most patients. Also, balloon tuboplasty is a feasible and safe proce-dure for dilating the ET.Keywords: Balloon dilatation; Eustachian tube; Eustachian tube dys-functionOP - 25TEMPORAL BONE AND SKULL BASE PARAGANGLIOMAS SURGICAL APPROACHKhassan Diab1, N.A.

1Federal Research Clinical Center of Otorhinolaryngology of Federal Medical Biological Agency of Russia, Moscow, Russia2Departament of Otorynolaryngology, Faculty of Postgraduate educa-tion, Pirogov Russian National Research Medical University, 117197, Moscow, RussiaObjective: Paraganglioma is a fairly rare tumor that arises from the cells of nonchromaffin paraganglia, also called glomus bodies, and therefore has many synonyms: glomus tumor, glomus tympanicum and glomus jugulare tumor, chemodectoma, receptoma, nonchro-maffin paraganglioma. The incidence of temporal bone paragan-glioma is 1:1300000. This is a benign tumor, but according to the literature, it can sometimes metastasize, even several years after a successful surgery. Our aim is to evaluate the effectiveness of surgical treatment of patients with paraganglioma. Materials and Methods: the article presents our five-year experience of surgical treatment of temporal bone paraganglioma. During the period from February 2015 to May 2021, 135patients with temporal bone paragangliomas underwent surgical treatment on the base of the National Medical Research Center of Otorhinolaryngology Federal State Budget-Funded Institution. The average age was 35,8 year, 36


men and 99 women. All patients were divided into 3 groups (A,B,C) taking into account the classification of U. Fisch and D. Mattox mod-ified by M. Sanna in 2013. Among them: 22(%) patients with type A tumor (12 cases of A1, 10 cases of A2 tumor); 73 patients with type B tumor (25 cases of B1, 16 patients of B2, 32 patients of B3 tumor); 35 patients with type C (12cases of C1, 13 cases of C2 - patients, 8 cases of C3, 6 cases of C4 tumor). Results: all the patients after detailed examination (CT scan, MRI with gadolinium enhancement) underwent surgery with total removal of paraganglioma. Type A paraganglioma was removed through the retroauricular tran-smeatal approach; in type B1 and B3 paraganglioma was performed extended canaloplasty; B2 paraganglioma was removed through the canal-wall-up approach; type C through – retrofacial and infratempo-ral approaches. Intraoperatively adequate visualization of important anatomical structures was obtained. In all cases of paraganglioma type A and B FN and lower cranial nerves function was preserved. In type C tumors the recovery of FN function up to grade 3 on the House-Brackman scale was noted. The hearing improvement was achieved in the majority of patients with type A and B tumors. There was no tumor recurrence according to CT, MRI scans and otoscopic examination 1, 2, 5 years after surgery (maximum observation time was 62 months).Conclusion: Сonsidering our experience in surgical treatment of tem-poral bone pathology, due to preoperative X-ray diagnostics, the use of vascular embolization, navigation system during the surgery, laser and microsurgical techniques under endovideocontrol, we managed to set up an algorithm for the tactics of surgical treatment of patients with this temporal bone pathology avoiding damage to the vital struc-tures of the lateral base of skull.Key words: glomus, infratemporal approach, retrofacial approachOP - 26REVISION OTOLOGIC SURGERIES; A RETROSPECTIVE ANALYSIS IN A TERTIARY CENTRE.Fatih Mutlu1, Hasan Mervan Değer1

1Kocaeli University, School Of Medicine, Department Of Otorhinolar-yngologyObjective: Revisions otologic surgeries have its own difficulties and challenges. The aim of this study was to evaluate the indications, the techniques to solve the problem, and the outcomes of the revision otologic surgeries at a tertiary referral center.Materials and Methods: We retrospectively evaluate the patient who had revision otologic surgeries in our referral center between June 2017 to December 2020. The indications, the operative techniques, and the outcomes of the revision surgeries were assessed.Results: Forty-nine patients from 463 otologic surgeries, performed by the same surgeon, were included in the study. Indications were graft failure in 26 patients (19 anterior, 4 inferior, 2 posterior, and 1 adhesion), hearing impairment after primary surgery in 6 patients (3 bone cement failure, 2 prostheses dislocation, and 1 fractured sta-pes), persistent leakage in 5 patients, cholesteatoma recurrence in 5 patients, attic retraction in 4 patients, and implantable hearing aid problems in 3 patients. Of the 19 anterior graft failures, 15 of them were medialization of the graft. The anterosuperior reperforations were more common. The anterior and inferior graft failures were revised with the anterior tab flap technique or placing gel foam under the graft. The graft success rate was 88.4% (23 of 26 patients) in the revision surgeries.Conclusion: With proper combination of over-underlay techniques

like anterior tab flap and supporting graft with gel foam from middle ear cavity increased graft take rates. Applying bone cement with a sin-gle continuous droplet decreased the break down of the material that causes conduction and had better closure of the air-bone gap. Partial obliteration of the canal wall down mastoidectomy cavities helped to have dry ear after the surgery. Using a cartilage to support attic pro-vided a stable epitympanum. With a proper and more careful surgery, revision otologic surgeries could be done with a high-rate success and without major complications. Additional graft enforcement or ossic-ular chain stabilization techniques looks necessary in some patients, and helps to achieve better results.Keywords : Revision surgery, otology, anterior tympanic membrane perforations.OP - 27CURRENT VIEW IN SURGICAL APPOACHES IN PETROUS BONE CHO-LESTEATOMA TREATMENTKh.M.

1 National Medical Scientific Center of Otorhinolaryngology of Federal Medical Biological Agency of Russia, Moscow, Russia 2Department of Otolaryngology, Faculty of Postgraduate education, Pirogov Russian National Research Medical University, Moscow, Rus-siaObjective: to evaluate results of surgical management of different types of petrous bone cholesteatoma.Materials and Methods: The authors retrospectively evaluated data from 121 patients who had undergone surgery between June 2016 and May 2021 at a National Medical Scientific Center of Otorhinolaryngology in Russia. On the pre-surgery stage facial nerve function (ENM), audiology results, CT and MRI scans were analyzed and all patients were classified into 7 groups according to D.Moffat classification (2008). All patients were surgically treated and followed up with radiology. The main outcome measures - classification, surgi-cal approach, intraoperative complications, disease control, audiologi-cal function and FN outcomes - were analyzed.Results: One hundred eighteen patients were eligible for study. The mean follow-up was 14.2 months. Out of 121 cases 11,6% (14) were infralabyrinthine, 34% (41) supralabyrinthine, 4,9 % (6) infralabyrin-thine-apical, 28,9% (35) massive,11,6% (14) supralabyrinthine-apical, 6,5% (8) massive labyrinthine-apical and 2,5% (3) apical. The facial nerve was involved in 58% of the cases and most frequently in the supralabyrinthine and massive group. The hearing could not be preserved in 72% of the cases due to the extent of the lesions. The internal carotid artery, jugular bulb, and the lower cranial nerves were involved in 98 cases and demanded meticulous care to avoid compli-cations. Recurrences were observed in 9 cases.Conclusion: Precise analysis of CT and MRI scans should be performed before surgery for identification of neurovascular structures involvement and adequate surgical tactic planning. Classic microscopic skull base approaches (adopted due to pathologic process) with endoscope revision of trepanation cavity at the end of the surgery are keys to adequate treatment of complex cases. Level and extension of involvement of facial nerve and internal acoustic canal in pathologic process plays important role in surgical approach choice. Radical removal takes priority over hearing preservation. Follow-up with CT, MRI T2, DWI non-epi imaging every 6 months is mandatory.Keywords : Petrous bone cholesteatoma, transotic approach, transco-chlear approach, translabyrinthine approach

The presence of intraoperative mid-dle ear cholesteatoma was recorded. The patients were followed up for 3 months postoperatively. Graft success was checked.Results: 102 of our patients were followed up closely postoperatively. At the postoperative 3rd month controls, it was observed that the grafts of 12 patients were not successful according to the examina-tions and audiograms performed. Cartilage island composite graft was used in 90 of our patients. Fat myringoplasty was performed in 1 patient. Grafts were placed in 9 of our patients using the endoscopic butterfly technique. Temporal muscle fascia and cartilage island com-posite graft were placed together in 2 patients with high Meri score. In the postoperative 3rd month audiograms, when compared to the preoperative audiogram, an average of 15 db gap was observed to be closed.Conclusion: As a result, the operation graft can be decided according to the results of the patient’s meri and amt score, as it was evaluated with the routine temporal tomography findings taken before tympa-noplasty, the demographic information of the patient, the presence of cholesteatoma.Keywords: tympanoplasty, meri-amt scoreOP - 29ROBOT-ASSISTED COCHLEAR IMPLANT IN A NEW VARIANT OF POU3F4 CAUSING DEAFNESS DUE TO INCOMPLETE PARTITION OF THE COCHLEAAhmet Mahmut Tekin1--2, Marco Matulic1, Wim Wuyts3, Masoud Zoka Assadi4, Griet Mertens5, Vincent van Rompaey5, Yongxin Li6, Paul van de Heyning5, Vedat Topsakal1

The IP-III anomaly is mainly characterized by incomplete separation of the modiolus of the cochlea from the internal auditory canal. IP-III of the cochlea is challenging for cochlear implantation (CI) surgery for two main reasons: liquor cerebrospinal gusher and electrode misplacement. This study aims to show that microsurgical robotic technology can be used in inner ear anomalies, with the

geometrically correct keyhole to access the inner ear.Materials and Methods: We describe a 71-year-old woman with profound sensorineural hearing loss diagnosed with an IP-III of the cochlea that underwent CI. Via targeted sequencing with a non-syn-dromic gene panel, we identified a heterozygous c.934G > C p. (Al-a31Pro) pathogenic variant in the POU3F4 gene that has not been reported previously. The HEARO® robotic system is an otological surgi-cal robotic platform with a focus on CI surgery.Results: Full insertion of the electrode array was performed and soft tissue with fibrin glue was used for tight packing and sealing of the cochleostomy. The system accuracy for this case was 0.13 and 0.04 mm at the level of the round window and facial nerve, respectively.Conclusion: The dedicated planning software (OTOPLAN®) allowed the surgeon to plan a 3D reconstruction of all relevant anatomical structures and designated the target on the cochlea and planned the most suitable trajectory to the cochlear round window. Surgically, in this case, it may be better to opt for a shorter array because it is less likely for misplacement with the electrode in a false route. Secondly, the surgeon has to consider the insertion angles of cochlear access very strictly to avoid misplacement along the inner ear canal. Genetic results in well describe genotype-phenotype correlations are a strong clinical tool and as in this case guided surgical planning and robotic execution.Keywords : DFNX2; POU3F4; IP-III anomaly; sensorineural hearing loss; image-guided surgery; robotically assisted cochlear implantation surgeryOP - 30THE CORRELATION BETWEEN RADIOLOGICAL TUMOR VOLUMES AND HEARING LOSS IN VESTIBULAR SCHWANNOMASErdem Mengi1

1Department Of Otorhinolaryngology, Head And Neck Surgery, Pamukkale University School Of Medicine, Denizli, TurkeyObjective: Vestibular schwannoma (VS) is the most common benign tumor of the posterior fossa originating from the vestibular nerve. Patients with VS most frequently present with complaints of unilateral sensorineural hearing loss and tinnitus. However, the pathogenesis of hearing loss in these patients is unclear. In this study, we aimed to evaluate the correlation between the hearing loss and the volumetric variables of the internal acoustic canal (IAC) and pontocerebellar angle (PSA) components of the VS by examining the magnetic resonance imaging (MRI) and audiometric data of the VS patients, at the time of initial diagnosis.Materials and Methods: In the study, the files of patients diagnosed with VS between January 2015 and December 2020 in our hospital were analyzed retrospectively. Patients who did not have audiometric data or MRI performed in our hospital at the time of initial diagnosis, and the patients with any additional disease that could cause hearing loss such as chronic otitis, otosclerosis, or Meniere›s disease were excluded from the study. Forty patients who met these criteria were included in the study. Demographic information of the patients, pure tone audiometric data, and speech discrimination scores (SDS) of both the ear with the tumor and the healthy ear were recorded. The volumes of the PSA components and the IAC components were measured using contrast-enhanced temporal bone MRI at the time of initial diagnosis. The correlation between tumor volumes and hearing results was examined based on the values obtained. Spearman correlation analysis was used to examine the relationships between numerical variables. In all analyzes, p <0.05 was considered


statistically significant.Results: Of the patients 25 (62.5%) were female, 15 (37.5%) were male and the mean age was 51.1 ± 12.27 (min-max: 23-73) years. In our study, there was a statistically significant moderate correlation, between the total tumor volume and the midfrequencies (p = 0.001, r = 0.491), high frequencies (p = 0.003, r = 0.439) and pure-tone average (PTA) (p = 0.002, r = 0.464) data obtained from the tumor side but no correlation was found between low frequencies and SDS. When the correlation between the volume of the PSA component of the tumor and the audiometric data was examined, similarly, a sta-tistically significant moderate correlation was detected between the midfrequencies (p = 0.002, r = 0.471), high frequencies (p = 0.008, r = 0.411) and PTA (p = 0.003, r = 0.452) but no correlation between low frequencies and SDS. The volume of the IAC component of the tumor was not correlated with hearing loss (p> 0.05).Conclusion: Hearing loss does not correlate with the invasion of IAC and shows a moderate correlation with total volume and the volume of the PSA component of the tumor. These findings suggest that tumor compression is not the only cause of hearing loss in VS.Keywords : Hearing loss, temporal bone MRI, vestibular schwannoma.OP - 31IS MAGNETIC RESONANCE IMAGING NECESSARY IN BELL’S PALSYHilal Yücel1

1University Of Health Sciences, Konya City HospitalObjective: We aimed to determine the temporal bone magnetic resonance imaging(MRI) rates for patients diagnosed with Bell palsy (BP), to investigate the relationship between MR results and disease severity, and to review the imaging recommendations for BP in the light of current guidelines.Materials and Methods: The files of the patients who were diagnosed with BP between September 2020 and February 2021 were retrospectively analyzed. Patients› age, gender, ear nose throat examination findings at first admission and House-Brackman (HB) grades at the 3rd month after treatment and imaging results were recorded. Post-treatment recovery degrees; Those with HB 1 and 2 were grouped as satisfactory recovery, those with HB 3 and above as unsatisfactory recovery. MRI results were compared between satisfac-tory and unsatisfactory recovery groups.Results: 81 patients were included in this study. Temporal MRI was performed in 62 (77%) patients, while MRI was not performed in 19 (23%) patients. Satisfactory recovery was found in 53 (85%) patients after treatment, while unsatisfactory recovery was found in 9 (15%) patients. While the MR imaging was normal in 39 (74%) of satisfactory group, neuritis was found in the facial nerve in 14 (26%) of them. While MR findings were normal in 5 (56%) of 9 patients with unsatisfactory group, neuritis was detected in 4 (44%) of them. There was no significant difference between the groups in terms of MRI findings.Conclusion: It would be more appropriate to wait for the treatment results rather than make a decision in the early period of the disease in order to decide on the imaging method in BP.Keywords: Bell palsy, Magnetic resonance imaging, facial paralysis

1Department Of Oto-rhino-laryngology And Head&neck Surgery, Fac-ulty Of Medicine, Süleyman Demirel UniversityObjective: To investigate whether there is a surgical-related difference in bone conduction thresholds (BCT) of patients operated on in our clinic for otosclerosis.Materials and Methods: Twenty-seven patients who were operated in our clinic between 2015 and 2019 and followed up with audio-metric measurements for at least 3 months after the operation were included in the study. Operations were performed by the same sur-geon, using the same technique (stapedotomy) and the same type of prosthesis (titanium). Pure tone audiometric thresholds before and after operations were compared.Results: The success rates were determined as very successful in eight, successful in 14, acceptable in three and unsuccessful in two patients. To compare BCTs, 22 patients who were accepted as func-tionally successful were evaluated. The average increase in the very successful group was 2.5 dB at 500 Hz, 17.5 dB at 1000 Hz, and 10 dB at 2000 Hz, while no change was observed at 4000 Hz. In the success-ful group, the average increase was 3.75 dB at 500 Hz, 8 dB at 1000 Hz, and 4 dB at 2000 Hz, but a decrease of 18.33 dB was observed at 4000 Hz.Conclusion: Sound applied to the bone conduction way is transmitted to the cochlea not only through the skull, but also with the participa-tion of the external auditory canal and ossicular chain. Therefore, we think that stapes footplate fixation may affect not only airway thresh-olds but also BCTs. We believe that analysis with larger case series is necessary for more reliable results.We believe that a better understanding of these changes in BCTs can help to improve the surgical technique and increase the success of the operation.

Materials and Methods: Medical data of 424 patients who underwent Type 1 Tympanoplasty and had preoperative HRCT scans were reviewed. HRCT scans were evaluated regarding the following pathologies: the presence of soft tissue in the middle ear, attic, mastoid antrum; pathologies of the ossicular chain; anatomical variations or bony wall defects of the sigmoid sins and the facial nerve canal; dehiscence of the tegmen tympani; tympanosclerosis (with or without ossicular chain involvement) and cholesteatoma. The presence of the above-mentioned pathologies was evaluated during the surgeries and positive and negative predictive value, specificity, and sensitivity of HRCT scans were calculated for each pathology.

Results:The most common findings in HRCT scans were soft tissue in the mastoid antrum (n= 77, 18.2%) and soft tissue in the attic (n=48, 11.3%). The most common pathologies encountered during the op-erations were soft tissue in the middle ear (n= 61, 14.4%) and tympa-nosclerosis (n=44, 11.4%). The highest sensitivity rate of HRCT was for soft tissue in the attic with 100%, the highest specificity rate was for facial canal dehiscence with 98.8%. Two-hundred-six (48.6%) patients had normal findings in preoperative HRCT scans. HRCT scans didn’t add to the clinical findings of these cases -therefore, didn’t affect surgical plans.Conclusion:The majority of patients who are candidates for Type 1 Tympanoplasty don’t benefit from HRCT scans by means of surgical plannings or adding to the clinical findings. Therefore, most of pa-tients don’t need HRCT scans before surgery. HRCT scans shouldn’t be considered as routine examinations before Type-1 tympanoplasty.Keywords: Tympanoplasty; chronic otitis media; temporal bone com-puted tomography; surgeryOP - 34COMPARISON OF ENDOSCOPIC AND MICROSCOPIC REVERSAL STAPEDOTOMY SURGERY: OUR CLINICAL EXPERIENCEAbdullah Dalgıç1, Abdülhalim Aysel1, Enes Aydın1, Gökçe Aksoy Yıldırım1, Levent Olgun2

1University Of Health Sciences, Izmir Bozyaka Training And Research Hospital, Clinic Of Otorhinolaryngology, İzmir, Turkey 2Department Of Otorhinolaryngology, Baskent University Hospital, İzmir, TurkeyObjective:We designed the present study to evaluate the demograph-ic, clinical, audiometric, and surgical results in patients who under-went endoscopic and microscopic assisted stapedotomy.Materials and Methods: We enrolled 87 otosclerosis patients who were scheduled to undergo endoscopic and microscopic stapedotomy procedures.Results: 44 procedures were performed using an endoscope, and 43 were done using a microscopic. Statistically significant variance was not found in the ABG values of both the groups before or after the procedures (p = 0.611).both the procedures achieved similar audiometric outcomes. The mean operative time was more significant in the last 22 patients of the endoscopic group than in the first 22 patients and the microscopic group (p = 0.027 and p = 0.018, respec-tively).Conclusion: An endoscopic approach involves a learning curve similar to that in other surgeries. The result obtained with the microscopic procedure was similar to that obtained using endoscopic surgery.Keywords : otosclerosis,endoscopic stapedotomy, microscopic stape-dotomyOP - 35EFFECT OF SYSTEMIC INFLAMMATORY MARKERS ON THE RADIOLOG-ICAL FINDINGS OF CHRONIC OTITIS MEDIASelin Dayısoylu1, Hüseyin Özay1, Tolga Ersözlü1, Erdoğan Gültekin1

1Tekirdağ Namık Kemal University, Department Of Otorhinolaryngolo-gy And Head And Neck SurgeryObjective: The aim of this study is to investigate whether neutrophil to lymphocyte ratio (NLR) and mean platelet volume (MPV) values are diagnostic in the evaluation of clinical activity in patients with active chronic otitis media (COM) and their relationship with bone erosion findings on radiological imaging.Materials and Methods: 133 patients with COM who had tympano-

mastoidectomy operation between 2015-2021 years in our clinic and whose medical records were accessed retrospectively were included in the study. 106 participants without comorbid diseases were select-ed as the control group. COM patients were divided into subgroups according to their pathology results as those with cholesteatoma and granulation tissue. The NLR and MPV values of patients in COM and control groups were recorded. All patients in the COM group were preoperatively evaluated with high-resolution computed tomography (HRCT) for facial canal dehiscence, lateral semicircular canal dehis-cence, scutum erosion, tegmen erosion, ossicular erosion and findings were recorded. In the first step of our study, the NLR and MPV values between the control group and the COM group were compared. In the second step, the NLR and MPV values between the subgroups of the COM group (cholesteatoma and granulation tissue groups) and the relationship of radiological findings with the NLR and MPV values were evaluated.Results: Pathology results of 59 patients from the COM group were reported as granulation tissue with the mean age of 30.66 ± 14.59 (11-58) and the M/F ratio was 31/28. The mean age was 38,64±16,57 (8-71) and M/F was 46/28 for 74 patients whose pathology results were reported as cholesteatoma from the COM group. M/F ratio of 106 patients in the control group was 52/54, mean age was 38.92 ± 17.35 (11-74). A statistically significant difference was found between the NLR (p = 0.013) and MPV values (p = 0.047) of the COM and control group patients (p <0.05). There was no statistically significant difference between in two subgroups of COM patients in terms of the NLR (p=0.108) and MPV values (p=0.428) (p>0.05). Between COM patients with bone erosion (45/133) and those without bone erosion (88/133), the NLR (p = 0.067) and MPV values (p = 0.352), there was no statistically significant difference (p>0.05). When we compared the COM patients with ossicle erosion (53/133) and without ossicle ero-sion (80/133) for the NLR (p=0,342) and MPV values (p=0,809), there was also no statistically significant difference (p>0,05).Conclusion: COM is a multifactorial pathology in which inflammation is considered as the main mechanism for the etiology. In the light of the findings of this study, it was observed that there was a significant relationship between the NLR and MPV values of the COM and con-trol group patients while the NLR and MPV values were not signifi-cantly related to bone erosion and ossicular damage in subgroups of COM patients.Keywords : cholesteatoma, chronic otitis, temporal bone, neutrophil to lymphocyte ratio, mean platelet volumeOP - 36INFLUENCE OF PROSTHESIS DIAMETER ON HEARING OUTCOMES IN PRIMARY OTOSCLEROSIS SURGERYDuygu Erdem1, Sultan Şevik Eliçora1

1Zonguldak Bülent Ecevit University, Medical School, Department Of OtorhinolaryngologyObjective: To evaluate the influence of prosthesis diameter on hear-ing results after primary small fenestra stapedotomy.Materials and Methods: The study included a retrospective medical chart review of 58 otosclerosis patients treated with primary small fe-nestra stapedotomy from Jan 2015 to Dec 2020. The study population was divided into two groups based on prosthesis diameter as 0.4 mm (39.6%, n=23) and 0.6 mm (60.4%, n=35). Preoperative and 6 months postoperative air-conduction pure tone average (AC-PTA), bone-con-duction pure tone average (BC-PTA), and air-bone gaps (ABGs) were compared between the two groups.Results: There were no statistically significant differences in de-


mographic data, mean preoperative AC-PTA and BC-PTA or ABGs between the two groups. Postoperative ABG ≤ 10dB and ≤ 20dB was achieved by 70.6% (n=41) and 100% (n=58) of the patients. No post-operative dead ear and/or sensorineural hearing loss (worsening in BC-PTA>10 dB) was noted in either group. Comparison of the 0.4 mm and 0.6 mm piston groups, revealed no differences regarding im-provements in AC-PTA (31.1 vs. 30.5 dB, p = 0.72), BC-PTA (3.8 vs. 6.2 dB, p = 0.34) and ABGs (7.9 vs. 7.7 dB, p=0.78).Conclusion: Primary small fenestra stapedotomy is an effective and safe procedure. A postoperative ABG within 10 dB was achieved in 70.6% of the patients and there was a reduced incidence of sensori-neural hearing loss. The hearing outcome was not influenced by the diameter of the selected prosthesis. Postoperative BC thresholds did not differ between the groups, which revealed no significant inner ear trauma caused by the larger piston.Keywords : Otosclerosis, Prosthesis, AudiometryOP - 37ANALYSIS OF THE RELATIONSHIP BETWEEN ISOLATED UNILATERAL CONCHA BULLOSA AND MASTOID AIR CELL VOLUMESFatih Yüksel1, Mehmet Erkan Kahraman1, İsa Deniz2

1Department Of Otorhinolaryngology, Konya City Hospital, Karatay / Konya, Turkey 2Department Of Radiology, Konya City Hospital, Karatay / Konya, Tur-keyObjective: The purpose of this study was to investigate the relation-ship between the pneumatization of mastoid air cells (MAC) and iso-lated unilateral concha bullosa (ICB) using computed tomography (CT) scans of the paranasal sinus.Materials and Methods: A retrospective review of paranasal sinus CT scans from 53 cases was performed. Cases with nasal septum angu-lation greater than 5 were excluded from the study. CT evaluations were made with a 128-slice multislice CT scanner in two projections, axial and coronal. Slice thickness was taken as 1 mm for volumetric analysis. Volume measurements were calculated using the Syngo.via Software Program by selecting the relevant anatomical region and using step-by-step addition and expansion processes. Volumes of the MAC’s (right and left) and ICB (right and left) were obtained and com-pared using statistical analysis.Results: The volume of MAC’s and ICB did not change with age, but the volumes of male subjects were larger than that of women. It was observed that the pneumatization of MACs on the side with ICB was significantly greater than for opposing MACs; however, no relationship was observed between the volume of MACs and the ICB volumes.Conclusion: Studies on the relationship between MAC pneumatiza-tion and nasal septum deviation and paranasal sinuses have shown different findings (1-4). Kim et al. (3) reported that there was a pos-itive correlation between MAC aeration and sphenoid sinus volume, but no correlation was observed between the volume of the maxillary sinuses. Gencer et al. reported that severe septal deviations caused a significant reduction in ipsilateral MAC volume (4). In our study, MACs on the same side as the ICB were found to be larger than the other side. In our study, It was concluded that the ICB caused a significant increase in the MAC volume on the side where they were located.Keywords : Concha bullosa, Mastoid air cells, Computed tomography, Volumetric analysis

OP - 38EVALUATING THE EFFECT OF TUBOTYMPANIC ANGLE IN MIDDLE EAR INFLAMATIONOzan Kuduban1

1Erzurum Regional Education And Research Hospital, Department Of Otolaryngology Head And Neck SurgeryObjective: Temporal Bone Computed Tomography (CT) is needed when evaluating the middle ear and mastoid. Middle ear disease is related with eustachian tube (ET) function and anatomic relations (1). In this retrospective study, we wanted to investigate whether tubotympanic angle affects mastoid pneumatization.Materials and Methods: In total, randomly selected 100 patients who underwent CT scanning in 2018 and 2019 in Erzurum Regional Education and Research Hospital were included. The patients were divided into two groups in terms of the mastoid pneumatization. The 50 patients had normal pneumatized mastoid cavity and the other 50 had mastoiditis on CT. Tubotympanic angle, which was considered the angle between the line extending through the tympanic orifice of the ET and the center of the longitudinal axis drawn from the bony exter-nal ear canal center, was measured (Figure 1).Results: We found the average value of tubotympanic angles 143.71° ± 6.50 in the patients with normal middle ear ventilation. The average value of tubotympanic angles was 146.30° ± 6.58° for the patients with mastoiditis. For the tubotympanic angle, no statistically signifi-cant differences were observed between two groups (p>0.05).Conclusion: The main function of ET is to provide middle ear venti-lation (1). When dysfunction of ET occurs, the pressure equilibration in the middle ear will be impaired, and the middle ear aeration be perturbed (2). In recent years it is thought that there may be associ-ated variations in the craniofacial anatomy of middle ear disease. In light of this, tubotympanic angle relative to the plane of ET have been measured(3). Some studies showed there is no difference between the tubotympanic angles of normal and control group (4). Likewise we didn’t find significant differance between healty and pathologic ears. Middle ear disease is relevant with dysfunction of ET rather than tubotympanic angle.Keywords : Ear, Middle; Eustachian Tube; InflammationOP - 39EVALUATION OF PITCH, MELODY AND TIMBRE PERCEPTIONS IN ADULT COCHLEAR IMPLANT USERSBaşak Mutlu1, Merve Torun Topcu1, Mustafa Yuksel2, Mahmut Tayyar Kalcioglu3

Süleyman Yalçın City Hospital, Ent ClinicObjective: The aim of this study is to analyze the relationships be-tween speech recognition in noise and perceptions of pitch, timbre, and melody in adult cochlear implant users with post-lingual hearing loss.Materials and Methods: The study included 18 adult cochlear implant users and 18 healthy individuals as controls. Before and after three months of music listening training, free field hearing thresholds, speech detection thresholds and word recognition scores tests, Turkish Matrix Test, and Clinical Assessment of Musical Perception

tests were performed in the study group and compared with the control group.Results: The mean age was 37.88 ± 16.65 years in the study group and 39.94 ± 12.13 years in the control group, and the mean ages were similar in the groups (p =.521). Significant improvements were observed in word recognition score (p =.047) and timbre recognition percents (p =.019) in the study group before and after the music listening training. Four multiple regression models were created to analyze the relationship between study group findings. Accordingly, it was found that the speech recognition in noise was significantly affected by the timbre recognition (R2

adjusted =.56), the mean free-field hearing thresholds with CI, and the word recognition scores (R2

adjust-

ed =.63). Word recognition scores were found to be affected by the most comfortable loudness levels (R2

adjusted =.40) and free-field hearing thresholds of 250 and 6000 Hz (R2

adjusted =.51).Conclusion: This study is the first which evaluate the relationship between the Turkish Matrix Test and musical perception.Tests of com-prehension and recognition of speech in noise and musical perception tests contribute to the functional evaluation of the cochlear implants and auditory rehabilitation program.Keywords : Cochlear implantation, Turkish Matrix Test, melody recog-nition, pitch discrimination, timbre recognition.OP - 40EVALUATION OF VHIT AND CVEMP RESULTS IN PATIENTS WITH MUL-TIPLE SCLEROSIS: PRELIMINARY RESULTSOğuz Kadir Eğilmez1, Abdülkadir Tunç2, Mahmut Sinan Yılmaz1, Meh-met Koçoğlu3, Mehmet Güven1

1Sakarya University Training And Research Hospital, Department Of Otorhinolaryngology, Sakarya, Turkey 2Sakarya University Training And Research Hospital, Department Of Neurology, Sakarya, Turkey 3Sakarya University Training And Research Hospital, Department Of Audiology, Sakarya, TurkeyObjective: This study aims to evaluate the vestibular system using electrophysiological test batteries like video Head Impulse Test (vHIT) and cervical Vestibular Evoked Myogenic Potentials (cVEMP) in Mul-tiple Sclerosis (MS) patients with and without brainstem involvement on Magnetic Resonance Imaging (MRI) and to determine whether there is a subclinical vestibular system disorder.Materials and Methods: Patients with a MS diagnosis and who did not have an attack in the last month were included in our study. Dizziness Disability Questionnaire (DHI) was applied subjectively and cVEMP and VHIT were applied objectively to evaluate the vestibular findings in the patients. Saccadic movements and VOR gains in vHIT; P13, N23 peak latencies and P13-N23 interpeak amplitudes were measured in VEMP. In addition, the hearing assessment was per-formed with pure tone audiometry. The results were evaluated by comparing them statistically with the control group.Results: In our study, 34 (27 females-7 males; 20-55 years old; mean 35.65 ± 8.4) with MS (group MS) and 20 healthy controls (group C) (15 females-5 males; 20-44 years; mean 33.4 ± 7.9) were included. The results of DHI were 38.35 ± 26.7 in group MS, and were significantly different from the group C. In pure tone audiometry, no significant difference was found between the two groups for air bone gaps in both ears. Lateral canal VOR gain averages in vHIT were 0.99 ± 0.13 and 0.97 ± 0.08 in group MS and C, respectively, and no significant difference was found (p=0.38). In cVEMP, the mean of P13 latency was 14.07 ± 1.6 and 13.51 ± 1.23 (p=0.08); mean of N23 latency was

22 ± 2.41 and 21.61 ± 1.91 (p= 0.17) and mean of P13-N23 interpeak amplitude were 102.51 ± 31.98 and 91.11 ± 35.14, respectively, in group MS and C (p= 0.07).Conclusion: Previously in the literature, it has been reported that VEMP responses can be used in the diagnosis of subclinical vestibular findings in patients without brainstem involvement, and vHIT can show semicircular canal pathologies in patients with known brainstem involvement. Although there were no statistically significant findings in our results, it was observed that the averages were affected in patients without MS compared to the control group, and results were both subjectively and objectively more pronounced in patients with brainstem involvement. The reported results are the preliminary re-ports of our study and we think that the results will contribute to the literature when the sufficient number of patients will be reached.Keywords : Multiple Sclerosis, VHIT, cVEMPOP - 41COCHLEAR IMPLANT USERS’ PERFORMANCE IN COMPLEX LISTENING SITUATIONSHilal Dinçer DAlessandro1

1Hacettepe University, Faculty Of Health Sciences, Department Of Audiology, Ankara, TurkeyObjective: This study aimed to investigate the effects of cochlear im-plant (CI) stimulation mode for complex listening tasks such as music perception and speech intelligibility in noise.Materials and Methods: The participants were unilateral, bilateral, or bimodal listeners (n=10/each group, ages: 20 to 65 years). The groups were similar for demographic factors such as age and duration of hearing loss before implantation. Speech perception in noise was assessed using the STARR test, developed to mimic everyday listening situations where both speech and noise levels varied together. The test was based on an adaptive paradigm to estimate a speech reception threshold (SRT), where 50% of the sentences were repeated correctly. The sentences were presented in randomized order at either 50, 65 or 80 dB SPL. Music perception assessment was performed using a music quality questionnaire for Classical Music, Jazz, and Soul.Results: Median STARR SRTs were 17.3 dB for unilateral, 10.3 dB for bilateral and 7.6 dB for bimodal listeners. Median bimodal gain for STARR performance was 10 dB. PTAs revealed statistically significant correlations with STARR performance (p<0.05). Median quality ratings from unilateral listeners were 50% for Classical music versus 60% for Jazz and Soul. Median ratings from bimodal listeners were 80% for Classical music versus 75% for Jazz and Soul.Conclusion: Present data show that complex but typical everyday listening tasks such as music perception and speech-in-noise are very challenging for CI listeners. This is mainly because both tasks share the same constraints of CI technology, especially for the transmission of dynamic and spectro-temporal cues of acoustic signals. Bilateral and bimodal listeners show considerably better performance for both tasks. Further studies in CI listeners with different stimulation modes may enlighten performance differences in relation to everyday perfor-mance and quality of life.Keywords : Cochlear implants, hearing aids, auditory perception, speech perception, music


OP - 42EVALUATION OF MIDDLE EAR FUNCTIONS WITH WIDEBAND TYMPA-NOMETRY IN POSTMENOPAUSAL PATIENTS WITH OSTEOPOROSIS.Eray Bayındır1, Gül Özbilen Acar1, Merve Torun Topçu1, Sadiye Murat2, Özlem Ertuğrul1

1İstanbul Medeniyet University Faculty Of Medicine , Department Of Otolaryngology 2İstanbul Medeniyet University Faculty Of Medicine , Department Of Physical Medicine And RehabilitationObjective: Wideband tympanometry (WBT) is a novel test method providing three-dimensional graphs of averaged tympanograms per-formed at frequencies between 226-8000 Hz. All tympanometric pa-rameters and absorbance findings can be evaluated within the same test session in WBT. The aim of this study is to investigate middle ear functions of postmenopausal women with osteoporosis and to reveal normative data of the groups by using WBT.Materials and Methods: Differences in WBT and pressurized-nonpres-surized absorbance results were investigated prospectively among postmenopausal patients of osteoporosis, osteopenia, and control groups. Normal-hearing women between the ages of 45-65 were in-cluded in the study. Three groups were formed as 30 postmenopausal women (60 ears) having osteoporosis, 30 women (60 ears) having os-teopenia, and 30 healthy women (60 ears) which comprised the con-trol group. After performing wideband tympanometry and pressur-ized-nonpressurized absorbance measurements, differences among the groups were noted and normative values were determined.Results: When nonpressurized absorbance values of the groups were compared, statistically significant difference was found at 1000-4000-5000 Hz between the control and osteoporosis group whereas there was no significant difference between the results of patients with osteopenia and osteoporosis. When pressurized absorbance values were compared, statistically significant difference was obtained at 4000 and 5000 Hz between the osteoporosis and control group. No significant difference was found between the osteoporosis and osteo-penia group. At 226 and 1000 Hz and equivalent ear canal volumes, significant difference was obtained between the control and osteopo-rosis group.Conclusion: Comparision of healthy adults with patients having oste-oporosis in which bone mineral density decreases yielding different results in WBT showed that ear ossicles could also be affected by mineralisation processes. In the presence of middle ear pathologies in postmenopausal women, besides the common causes, changes in middle ear functions due to osteoporosis should be kept in mind in differential diagnosis.Keywords: postmenopausal osteoporosis , wideband tympanometry , osteopenia , middle ear function

According to the file information, language, articulation, fluency, and voice evaluation findings accompanying with speech disorder were also investigated. All tests were performed by an audiology and a speech disorder spe-cialist.Results: Of the 93 patients in the study, 68 (73.1%) were male and 25 (26.9%) were female. The mean age of the patients was 39.35 ± 18.82. In the study, the total speech disability score was found to be 24.63±8.83 in those with consanguineous marriage and 19.37±7.15 in those without consanguineous marriage. The total speech disability score was 19.47±7.11 in those who used hearing aids and 21.37±8.47 in those who did not use hearing aids.Conclusion: Only the articulation obstacle score was higher in hear-ing aid users and it was statistically significant. Language, voice, and fluency obstacle scores were found to be higher in those who did

not use hearing aids. Those with consanguineous marriages had the higher voice and total speech obstacle scores. It was observed that the lower the education levels correlate with the higher the speech impairment scores. Although the total score of speech obstacle was higher in those with a family history compared to those without a family history, no statistically significant difference was observed.

1Ankara Yıldırım Beyazıt University , Ankara , TurkeyObjective: Although decreased sound tolerance (hyperacusis) and misophonia are intertwined concepts, clinically they represent diffe-rent situations. It is known that there maybe changes in hearing sensi-tivity and auditory perception in different age groups. It was aimed to examine the relationship between misophonia findings and reduced sound tolerance individuals at different age groups. Materials and Methods: Three hundred three individuals (97 males and 206 females) between the ages of 18-65 participated in the study. Individuals were evaluated under two groups (18-40 and 41-65 years old). Demografic form created by researchers, Misophonia Evaluati-on Form which includes 50 sounds and 20 questions that can disturb people and the Khalfa Hyperacusis Scale consisting of two parts and 17 questions were used to measure the presence of decreased sound tolerance. The questionnaires were applied to the participants online. Results: It was observed that 19 (6.3%) of the individuals who parti-cipated in the study had hyperacusis. Out of the 19 individuals iden-tified as having hyperacusis, 17 (89.5%) were female and 2 (10.5%) were male. Nine (3%) of the individuals participated had misophonia symptoms. Of those with misophonia symptoms, 8 (3.9%) were fema-le and 1 (1%) was male. It was observed that 15.5% (n=47) of the indi-viduals had complaints of tinnitus and/or 29.7% (n=90) had a mental illness. There was no significant relationship between the age group and the presence of hyperacusis. (P = 0.70) No significant relations-hip was found between the age group and presence of misophonia. (p=0.503) A significant correlation was found between the presence of hyperacusis and the presence of misophonia. (p=0.014) Conclusion: This study shows that the age variable was not an im-portant factor on decreased voice tolerance and misophonia. It was observed that decreased voice tolerance and presence of misophonia were more common in women. The relationship between decreased sound tolerance and the presence of misophonia was stunning.

of the disease. Immune-mediated processes in MS can damage the peripheral auditory system. The aim of this study is to evaluate the functioning of the medial olivocochlear efferent (MOC) system in patients with multiple sclerosis with normal hearing, using the con-tralateral suppression test to evaluate the integrity of the efferent auditory pathways. To investigate the presence of subclinical cochlear dysfunction.Materials and Methods: Ondokuz Mayıs University Neurology Clinic admitted patients were included in the study. Initial analysis of 27 multiple sclerosis patients with click-evoked otoacoustic emission measurement. If subjects had reproducible otoacoustic emissions at 80 dB SPL, suppression of otoacoustic emission with contralateral acoustic stimulation was measured with a 65-dB white noise stimu-lus. This resulted in inclusion of 54 ears of multiple sclerosis patients. Transient Otoacoustic Emission (TEOAE) test was carried out in the absence and presence of contralateral noise. The obtained contra-lateral suppression values were compared between right and left ear. Suppression was calculated in half-octave frequency bands cen-tered at 1.0, 1.5, 2.0, 3 and 4.0 kHz.Results: There was no statistically significant difference between the signal-to-noise ratios (p: 0.67 ) and MOC reflex results (p: 0.06) between the right and left ears in patients with MS. Afferent and efferent system differences were not observed between the ears in MS disease.Conclusion: According to the data obtained, there is no statistical difference between the right and left ear suppression values. Studies with more patients are needed to determine the subclinical effect in patients with MS.Keywords: Autoimmune diseases, Hearing loss, Contralateral suppres-sion, Efferent Auditory SystemOP - 48INVESTIGATION OF THE RELATIONSHIP BETWEEN DISEASE ACTIVITY AND SLEEP AND DEPRESSION IN VESTIBULAR MIGRAINEMustafa Çam1, Erkan Tezcan1

1Çanakkale Onsekiz Mart UniversityObjective: The clinical condition in which vertigo, dizziness and balance disorder are seen together with migraine attacks is called vestibular migraine (VM). Migraine can have a disruptive effect on the vestibular system. Our study, the relationship between sleep and depression, which can trigger migraine, and disease activity was investigated.Materials and Methods: 43 patients diagnosed with VM were included in the study. Dizziness and headache severity were evaluated with the Visual Analogue Scale (VAS). Beck Depression Scale (BDI) was used to evaluate depressive symptoms. Sleepiness was assessed with the Epworth Sleepiness Scale (ESS). The relationship between VAS and BDI and EUS was examined using the Pearson correlation test. In addition, the patients were divided into two groups as those with VAS scores of 5 and below (Group 1) and those with 6 and above (Group 2), and sleep and depression status were compared with the Mann-Whitney U test between these two groups.Results: The age distribution of the patients was between 18 and 46 and the mean age was 31.74. No significant relationship was found between gender and age and VAS. A positive correlation was found between VAS and sleep and depression scales. The mean score of depressive patients was found to be statistically significantly higher in Group 2 than Group 1 (p <0.001, Mann Whitney U test).

Conclusion: Vestibular migraine appears to be more severe in patients with sleep disorders and depression. This study suggests that vestibular migraine patients should be evaluated more carefully in terms of sleep and depression. Treatment of patients with sleep and depression may be beneficial in reducing the severity of vestibular migraine.Keywords: Vestibular Migraine, Sleep,DepressionOP - 49THE EFFECT ON PAIN OF DIFFERENCES IN THE APPLICATION AND DURATION OF TOPICAL ANAESTHESIA BEFORE INTRATYMPANIC INJECTIONMert Cemal Gökgöz1, Hamdi Taşlı2, Hakan Genç3

1Manisa City Hospital, Dept. Of Otolaryngology, 2Kütahya Health Sciences University, Evliya Celebi Training And Re-search Hospital 3University Of Health Sciences, Gülhane Medical SchoolObjective: Drug applications with intratympanic injection have been applied in practice with increasing frequency over the last 20 years. The basic aim of intratympanic injection applications is to allow a high concentration of the drug to reach the inner ear via the round win-dow and to avoid systemic side-effects. The aim of this study was to compare topical anaesthesia methods applied for different durations before injection in patients planned to receive intratympanic steroid injection and to evaluate patient comfort.Materials and Methods: This prospective study included patients who were to be applied with intratympanic injection treatment for the first time. Topical mucosal anaesthesia was administered 5, 10, or 15 mins before the intratympanic injection. The patients were sepa-rated into two groups as the Spray group and the Cotton group. The level of pain felt by the patients was evaluated using a Visual Analog Scale (VAS) immediately after the injection (VAS-0) and 15 mins later (VAS-15). The study was approved by the Local Ethics Committee.Results: The study included 102 patients applied with intratympanic steroid injection for the first time because of sudden hearing loss, Meniere’s disease, and tinnitus. In the Cotton group, applied with cotton impregnanted with a mixture of lidocaine and prilocaine cream, according to the ANOVA test results, a statistically significant difference was observed in the VAS-0 values with topical anaesthesia applied at 5, 10, or 15 mins before the injection (p:0.026). With the t-test applied to the dependent variables, a difference was calculated in the comparison between 5 and 10 mins (p:0.025) and in the com-parison between 5 and 15 mins (p:0.020). In the evaluations made within the groups, a statistically significant difference was observed between the VAS-0 and VAS-15 values.Conclusion: The application of lidocaine spray only was seen to provide better pain management, although in both groups, the level of pain was evaluated as tolerable. It was seen that it was necessary to wait for a longer period to obtain anaesthesia in the Cotton group.Keywords : Intratympanic injection, Sudden deafness, Complications, Pain.

OP - 50EVALUATION OF THE RELATIONSHIP BETWEEN DISABILITY AND STAT-IC BALANCE IN VESTIBULAR MIGRAINE PATIENTSBaşak Mutlu1, Sıdıka Cesur1

1Istanbul Medeniyet University, Faculty Of Health Sciences, Depart-ment Of Audiology, IstanbulObjective: Vestibular migraine (VM) affects the quality of life nega-tively by causing chronic and/or episodic dizziness and imbalance. The aim of this study is to analyze the effects of gait balance, fear of fall-ing, and static balance functions on quality of life-related to balance impairments in VM patients.Materials and Methods: The study included 23 VM and 23 healthy controls aged between 18-70 years. Dizziness Handicap Inventory (DHI), Fall Efficiency Scale (FES), Dynamic Gait Index (DGI), and static posturography tests (limits of stability, body sway, and fall risk) were applied to the participants. At the time of the tests, VM patients were in the non-attack period. Statistical analyses of the relationship be-tween DHI and other parameters were performed.Results: The ages (p = 0.886) and gender distributions of 23 VM patients (4E, 19K, 44.34 ± 7.58 years) and 23 controls (4E, 19K, 45.56 ± 10.69 years) included in the study were similar. The static balance parameters of the VM group, sway velocity indexes (p = 0.024), and limits of stability scores (p˂0.049) were found to be significantly worse than the control group. DHI total and sub-scores were significantly correlated with FES (r˃0.8, p˂0.001) and DGI (r˃766, p˂0.001). There were also significant correlations between the DHI scores and the eyes open and eyes closed sway velocity indexes (r = 0.452, p = 0.03, and r = 0.484, p = 0.021, respectively) and direction control scores (r˂0.414, p˂0.05). There was no significant relationship between DHI and Body Sway test scores. Conclusion: In this study, we evaluated DHI, FES, DGI, and the static postural stability (using body sway, fall risk, and limits of stability parameters) in VM patients and controls and investigated the relationship between the results. We found that the static balance scores statistically differed between groups and the scores of the VM group were significantly worse than the control group. This is consistent with previous findings of increased sway velocity especially when the eyes were closed or the platform was distorted in patients with VM. In the current study, it was also found that there were significant correlations between the DHI scores and the eyes open and eyes closed sway velocity indexes and direction control scores. This study is important because it is one of the rare studies evaluating static posturography and DHI findings in VM patients. Using the limits of stability test as well as specific questionnaires in the assessment of disability in VM is an effective method in determining the extent of patients’ efficacy from symptoms.Keywords : Vestibular Migraine, Dizziness Handicap Inventory, Dy-namic Gait Index, Fall Efficiency Scale, static posturography.

OP - 51RETROSPECTIVE ANALYSIS OF OUR BENIGN PAROXYSMAL POSITION-AL VERTIGO PATIENTSHüseyin Sarı1

1Department Of Otolaryngology-head And Neck Surgery, Prof. Dr. Cemil Taşçıoğlu City Hospital, Istanbul, Turkey.Objective: Benign paroxysmal positional vertigo (BPPV) is one of the most common vestibular disorders. Although posterior canal BPPV accounts for 90% of patients, other canals can also cause BPPV at different rates. In the treatment, specific repositioning maneuvers are applied to the affected canal. Therefore, it should be known which ca-nal is affected. Our study aimed to investigate the age, gender, canal involvement, and recurrence rates of patients diagnosed with BPPV and treated with repositioning maneuvers retrospectively.Materials and Methods. 440 patients diagnosed with BPPV who were followed up in our vertigo outpatient clinic between January 2019 and January 2021 were retrospectively analyzed. We divided the patients into three different age groups and analyzed them in terms of age, gender, canal involvement, and recurrence rates.Results:The mean age of the patients was 51.99, 312 (70.9%) of them were female and 128 (29.1%) were male. BPPV was more common in the middle age group 41-60 years old. Posterior canal BPPV, which constitutes 63.8% of the cases, was the most common, while superior canal involvement was rare (2%). Canalolithiasis was more common in the posterior canal (86.1%), while cupulolithiasis was more common in the lateral canal (57.8%) (p = 0.001).Conclusion: In our study, there was no difference between the affect-ed ear sides. This is inconsistent with the literature stating that the right labyrinth is involved more frequently and that patients mostly sleep on the right side. In addition, multiple canal involvement was observed more frequently than in the literature (n = 60; 13.6%).The posterior semicircular canal is most commonly affected in BPPV. According to age groups, there was no difference between the canal theory, the affected ear, and the involved canal. While canalolithiasis was higher in the posterior canal, cupulolithiasis was higher in the lateral canal.Keywords : Benign Paroxysmal Positional VertigoOP - 52CLINICAL APPROACH TO DIFFERENTIAL DIAGNOSIS OF VESTIBULAR MIGRAINE AND MENIERE’S DISEASEHandan Yaman1, Burcu Polat2, Mustafa Bülent Şerbetçioğlu3

In this study, it was aimed to examine the relationship between these diseases by evaluating the auditory and vestibular evaluations of the patients diagnosed with VM and MD, as well as the patients’ complaints.Materials and Methods: 42 patients who applied to Istanbul Medipol University Neurology and ENT clinic and diagnosed as VM as a result of audiological and neurological evaluations, and 56 patients diagnosed with MD who applied to the ENT clinic were included in the study. Hearing thresholds, speech audiometry, o/c-VEMP responses, caloric


test measurements, complaints of tinnitus, ear fullness and motion sickness were evaluated.Results: When the hearing thresholds were compared, significant dif-ference was observed between the groups in the comparison covering all ears(p<0,05), whereas only ears with hearing loss were compared, no significant difference was observed between the groups(p>0,05). When the hearing thresholds of normal ears were evaluated between the groups, a significant difference was found in SRT and SDS val-ues(p<0,05). No significant difference was found between the groups regarding o/c-VEMPs latencies and amplitudes of P1 and N1, and pres-ence-absence of o/c-VEMPs. N1-P1 asymmetry ratio in c-VEMP was significantly higher in MD(0,23 ± 0,21) than VM(0,19 ± 0,12) (p=0,019). It was observed that the complaints of tinnitus, ear fullness and canal paresis were significantly higher in MD compared to VM(p <0.01). 71% had tinnitus and 53% had ear fullness complaints of MD group were unilateral. Motion sickness complaints of VM were found to be signifi-cantly higher than MD(p <0.01).Conclusion: This study describes many differences between MD and VM, some of which are statistically significant. There are many overlaps between the two diseases in terms of diagnostic criteria. Clarifying the blurry line between the two diseases can helpful clinical diagnosis and treatment.Keywords : Migraine, tinnitus, caloric testOP - 53EFFECTS OF REPETITIVE INTRATYMPANIC STEROID INJECTION ON OBJECTIVE AND SUBJECTIVE BALANCE TESTSCoşkun Atay1, Ozan Gökdoğan 1--2, Çağıl Gökdoğan1--2, Kerimcan Çakıcı1, Mahmut Demirtaş1--2, Sabri Köseoğlu1--2, Erdoğan Özgür1, Harun Üçüncü1--2

1Mugla Sitki Kocman University, Faculty Of Medicine, Department Of Otorhinolaryngology 2Mugla Sitki Kocman University, Hearing And Balance Disorder Studies Research And Application CenterObjective: Sudden sensorineural hearing loss (SSHL)is one of the challenging issues amongst the ENT emergencies. Treatment op-tions are steroid treatment and hyperbaric oxygen treatment(1). Although its well known improving effects on hearing levels, we are short on information about intratympanic steroid injections on bal-ance mechanism(2).Our study aimed to reveal the effects of intratym-panic steroid injection to the balance mechanism.Materials and Methods: Patients with age between 18-65 and uni-lateral hearing losses were included. Patients with unilateral SSHL had systemic steroid as an initial treatment and followed up for 10-14 days. 22 patients who did not respond oral steroid treatment were treated by intratympanic steroid administration. Video Head Impulse Test ( VHIT) battery for evaluating objective vestibuloocu-lar reflex(VOR) gaining and Dizziness Handicap Inventory (DHI) for evaluating subjective complaints, were used. Patients had 3 or 5 intratympanic dexamethasone injection to the affected ear. After the termination of the IT therapy, patients were planned to run VHIT and DHI tests, and compared with the tests made before IT therapy, in or-der to understand its effects on the balance system. One patient with suspected intracanallicular vestibular schwannoma, 1 patient with bilateral hearing loss and 3 patient with missing data, of 5 patients were excluded from the study.Results: Total of 17 patient were included to the study. Nine were male(52%) whereas 8 were female(48%). Mean age was 45,35± 11,13. Out of 34 ears , 9 ear of the patients (26,7%)had disease in left ear,

whereas, 8 ears (23,5%) had in right ear. Mean IT injection episode was 3,06 times. Concerning frequencies between 500-4000hz mean air conduction levels improved from 57.6dB±36,54 to 48,58dB±43,58 which was statistically significant different(p=0,026). Mean VHIT scores were decreased from 30±22,02 to 25±16,6 which was sta-tistically signifacantly different(p=0,018). We found 17,6% of the ears with a specific semicircular canal (SSC) VOR deficiency before IT treatment, either lateral or posterior canal without anterior canal involvement, had the posterior and/or lateral canal involvement after IT treatment. In VHIT test 20,5% of ears which had had lateral and/or posterior canal involvement completely resolved after IT therapy. And 14,7% of the ears with a normal VHIT findings before IT injection, had canal weaknesses in lateral and/or posterior canal after the ther-apy. For hearing loss treatment after IT treatment 8 of 17 patients fully recovered and 9 was referred to the HBO therapy.Conclusion: IT dexamethasone injection have variety of effects on vestibular system, especially on VOR reflexes. Therefore before IT treatment it is crucial to question the patient about vertigineous symptoms to estimate potential effect and side-effect of the treat-ment.

1Bakırköy Prof Dr Mazhar Osman Training And Research Hospital For Mental And Neurological DiseasesObjective: It is known that 72% of patients with migraine describe symp-toms of dizziness or vertigo, during prodromal or attack period. In this study, it was aimed to evaluate the demographic and clinical characteris-tics of patients with migraine associated vertigo and to compare the char-acteristics of patients with vertigo during the prodromal or attack period.Materials and Methods: A retrospective chart review of patient with headache, between 2015–2020 as performed. Patients with migraine associated vertigo symptoms during prodromal or attack period was included for further analyses. Patients who had sufficient etiological workup and evaluated by an otolaryngologist at least once were included in the study. The demographic and clinical characteristics were docu-mented. Patients with vertigo in prodromal (PP group) and attack period (AP group) were compared.Results: The mean age of 22 patients (19 female, 3 male) was 45.6 (22-57), the age of onset of the disease was 20.7 (7-34) and the duration of the disease was 24.9 years (11-47).16 patients were diagnosed with migraine without aura, 2 patients with migraine with aura (visual), 3 patients with chronic migraine and 1 patient with vestibular migraine. 16 patients described vertigo during migraine attacks and 6 patients in the prodromal period.17 patients described rotational vertigo and 5 patients described position-induced vertigo. Two patients had tinnitus. Vertigo continued throughout the period in patients with vertigo during attack. It was observed that photophobia, phonophobia and nausea-vomiting were common. All patients admitted attack treatment and 21 patients used prophylactic agents. No significant difference was found between PP ve AP groups regarding age, age at onset, duration of disease, dura-tion of pain, and frequency of pain (p=0.115, p=0.178, p=0.449, p=0.541, p=0.735, respectively).Conclusion: It was observed that 86% of patients with migraine-associat-ed vertigo were female, consistent with the literatüre. Photophobia, pho-

nophobia and nausea-vomiting accompanied the majority of patients. Although it has been suggested that migraine with aura were mostly accompanied by vertigo, 86% of the patients had migraine without aura. Vertigo was common during attack period. However, no significant differ-ence was found between the PP and AP groups in terms of demographic and clinical characteristics.Keywords : vestibuler migraine, migraine associated vertigo, migrainous vertigoOP - 55VESTIBULAR IMPAIRMENTS IN CHILDRENFaruk Kadri Bakkal11Usak University, Medical Faculty, Department Of OtolaryngologyObjective: To evaluate the frequent causes of vertigo and dizziness in children.Materials and Methods: Patients under the age of 18 (n= 263) who applied to the Otorhinolaryngology Clinic of Uşak University Hospital between January 2019 and January 2021 with vertigo were included the study. Data obtained from patient records were analyzed retrospectively.Results: The mean age of the cases, 84% (n= 220) of which were adolescents, was 14.1(±2.66) years. The most common etiological groups were psychogenic dizziness (%42), vestibular neuritis (29%) benign paroxysmal vertigo of childhood (BPVC) (13%), and migraine-associated vertigo (MAV) (9%). MAV and BPVC were more common in young children, while psychogenic dizziness was the most common diagnosis in adolescents (p<0.001).Conclusion: Although vertigo is not common in children, it is a caution-ary symptom. Psychogenic dizziness, which accounts for about half of pediatric dizziness, is often confused with other etiologies of vertigo. Migraine-related vertigo accompanied by headache is another cause of vertigo to be considered in children. In children, the symptoms are often intertwined and it may not be easy to reach the differential diagnosis. An accurate clinical history and a complete otological and neurological exam-ination is crucial to proper evaluation. Otological causes such as trauma, otitis, Meniere’s disease may cause dizziness in children, as well as many central causes such as epilepsy, vascular and degenerative diseases. Verti-go in children can be intertwined with complex symptoms. Achieving the correct diagnosis and treatment often requires close collaboration with other medical disciplines.

Regular exercise not only provide proper posture, but also affect many systems in the body. One of these systems is the vestibular system. The aim of this study is to evaluate the vestibular systems of professional athletes who regularly engage in physical activity in their daily lives and office workers who do not engage in regular physical activity.Materials and Methods: A total of 100 individuals (23 females, 77 males) between the ages of 20-50 participated in the study. Professional athletes (PA) (50 people) who regularly engage in physical activity constitute the study group, and normal individuals (NI) (50 people) who do not engage in regular physical activity constitute the control group. For the PA group,

the condition of doing professional sports regularly for at least 5 years was inclusion criteria. Romberg Test, Tandem Romberg Test, One Leg Standing Test, Timed Up-Go Test, Tinetti Balance and Gait Assessment Scale were used.Results: The mean age of the individuals participating in the study was 30.5±8.47 years (min:20, max:50 ). There was no significant difference between PA and NI groups in regard to Romberg Test, Tandem Romberg Test, Standing on One Leg performed with eyes open and closed and Timed Up-Go Test results (p > 0.05). However in the Tinetti Balance and Gait Assessment Scale, there was a significant difference between the PA and NI groups (p< 0.05).Conclusion: This study shows that there was no difference in the static balance performances of the individuals in the professional athletes and office workers, but regular physical activity had an effect on the gait evaluation. Regular physical activity is thought to be more effective on dynamic balance. In future studies, is recommended to use objective tests with higher sensitivity when evaluating the Vestibular System on the same group and to apply the study to more people.Keywords : vestibular system, physical activity, balance, office workers, professional athleteOP - 57ACUTE VERTIGO DIAGNOSIS AND TREATMENT PERSPECTIVE OF EMER-GENCY PHYSICIANS AND PRIMARY CARE PHYSICIANSYuşa BAŞOĞLU1, Melike Nur DEDE1, Berrin YILMAZ1, M.

There were 37 emergency physicians (EPs) and 42 primary care physicians (PCPs). The questionnaire consisting of 13 questions was applied via Goo-gle Form. Chi-square and Multiple Response analysis by IBM SPSS STATIS-TICS-26 version were used for data analysis.Results: Our study, in the diagnosis of BPPV, Vestibular Neurinitis, Me-niere’s Disease (MD), Non-specific vertigo respectively; Dix-Hallpike (43.0%), neurology consultation (24.0%), temporal CT (16.8%), neurology consultation (33.3%) were obtained. In the treatment section, Betahistine was preferred, including BPPV (EPs30,8%; PCPs%41,1%), Neurinitis (EPs 30.3%; PCPs 42.4%), MD (EPs23.7%; PCPs 32.9%), at Non-specific vertigo (EPs31.9%; PCPs 45.5%).Conclusion: In our study, HINT (20.0%) and Dix-Hallpike (30.2%) were cho-sen less by PCPs. In the literature, it has been shown that the Epley maneu-ver is up to 89% effective in posterior canal BPPV. In our study, preference for the Epley maneuver in BPPV cases was 24.5%; prescription of betahis-tine was found to be 35.8%. Short-term use of pharmacological approach-es in acute phase is known. It has been shown in the literature that 1.49% of the $1.230.840 budget spent on imaging techniques (MRI, CT) was used for meaningful results and 1.2 million is saved when the correct procedure is followed. In our study, 2 of every 10 physicians in MD had a 21.5% CT re-quest. The etiology of vertigo is usually determined only by anamnesis and physical examination. In diagnosis-treatment; In order to prevent time loss and unnecessary examinations, the approach to the patient with vertigo must well known. Awareness of maneuvers must be ensured and use of increased such as HINT, Dix-Hallpike, Epley Maneuver.

OP - 58A RARE REASON OF CSF OTORRHEA AT MIDDLE EAR PATHOLOGIES: ARACHNOID CYSTS OF FALLOPIAN CANALAyça Başkadem Yilmazer1, Yavuz Uyar1

1Istanbul Prof Dr Cemil Tascioglu City Hospital, Ent ClinicObjective: To emphasize that the rarely seen arachnoid cysts should be considered in differential diagnosis in presence of the CSF otorrhea Method: This is a retrospective cohort study. Our two cases and the medical records from Pubmed and Google Scholar searches were re-viewed. To research the literature, “arachnoid cyst + ear, internal acoustic canal, fallopian canal, facial canal” words were used in search engine of the websites.Results: A total of 27 articles and our two cases were reviewed. 24 of the total articles were case reporting, the rest were cadaveric temporal bone reporting. %52 of the cases were in internal acoustic canal with the symptom of hearing loss and tinnitus, and the rest were in the fallopian canal with the symptom of facial palsy and CSF otorrhea. Only one case had bilateral arachnoid cyts in the fallopian canal. In our cases, arachnoid cysts were located in the fallopian canal, around the geniculate ganglion. In case-1, during the mastoidectomy surgery, a sudden CSF leakage was observed and we thought that if there was an injury in dura or semicir-cular canals. Then, an arachnoid cyst was recognized under sac of the cholesteatoma . In case-2, the patient had chronic serous otitis and mir-ingoplasty was performed in an outpatient clinic. Then, consistent serous leakage was observed and radiologic imaging was performed. Bilaterally, arachnoid cyts at geniculate ganglion were identified.Conclusion: Our first case was an important entity in terms of being aware in the surgery if the CSF leakage because of a complication or an arachnoid cyst. The other case was unique since bilateral arachnoid cyts in the fallopian canal were observed very rarely. As a conclusion, arach-noid cysts should be considered in differential diagnosis of the CSF otor-rhea at middle ear pathologies.Keywords: arachnoid cyts, fallopian canal, internal acoustic canal, CSF otorrhea

OP-59A NOVAL METHOD IN OTOLOGIC DOCUMENTATION: UTILIZATION OF IMAGE-J SOFTWARE IN TYMPANIC MEMBRANE PERFORATIONSBurak Ülkümen1, Onur Çelik1

1Manisa Celal Bayar University Otorhinolaryngology DepartmentObjective: To define how to determine the exact area of tympanic mem-brane perforations by Image-J software.Material and methods: Otoendoscopic view of a patient with chronic otitis media was used for evaluation. A 2 mm ear curette was used for setting the exact scale. After running the Image-J software the jpeg file of otoendoscopic view was opened. The scale was set by the line tool for delineating the diameter of the curette which we already had measured as 2mms. This line was used for setting the scale for whole of the jpeg file. After that, two different methods were used to determine the margins of perforation: i) the free brush tool and ii) color threshold adjustment. Next, we the area of the perforation was determined by the measurement function of the software.Results: The area of perforation was measured as 4.403 and 4.161 square millimeters by free brush tool and color threshold adjustment, respec-tively. On the other hand, we also measured the perforation in pixels as 14.373 and 14.628 by both methods, respectively. There is a standardiza-tion problem in the documentation of tympanic membrane perforations in clinical studies especially on tympanoplasty. Various methods are used to determine the perforation size, area, shape and location in chronic otitis media which all have some serious limitations (1,2). Mainly, three different measuring methods are used: (i) diameter, (ii) area or (iii) per-centage. Even then, every single method differs between studies. For example, concerning the percentages of involved tympanic membrane, Singh et al. classified them in three ways, i.e., “tiny” (<5%), “moderate” (>5% to <50%) and large (>50%), but without reporting the technique (3). Abdelhameed et al. also classified them in three ways, but differently, i.e., 23 mm2 (> 50%), 23-45 mm2 (25% to 50%), 45 mm2 (≤ 25%), with mea-suring carried out by using a silastic sheet that just fitted the perforation (1). In our previous study, we measured perforation size by evaluating the otoendoscopic views by ImageJ regarding involved percentages for the first time. But there is a need for more precise documentation of tym-panic membrane and/or other microanatomic structures of middle ear for more reliable statistical analyses. Based on this need, we defined the utilization of ImageJ software for otological documentation and analysis in a more precise way.Conclusion: Hereby we defined a new way to determine and analyze the exact area in square millimeters rather than the proportion of the perforation which was previously reported (4, 5). Thereby, regardless of the way of image acquisition (endoscopic or microscopic), the area of tympanic membrane perforation or different microanatomical structures of the middle ear can be precisely determined. Eventually, it would be possible to make more accurate statistically analyses in the future otolog-ical clinical studies.

Cholesteatoma cases occurring in different regions of temporal bone at the same time have been reported in the literature. However, as in our case, no cases of double cholesteatoma have been reported in the same region of the temporal bone. We will present a case of double cholesteatoma on the lateral semicurcular canal (LSC) in a recurrent case previously operated for cholesteatoma.Case: A 66-year-old male patient, who was operated 18 years ago for cholesteatoma, presented to us with the complaint of dizziness vertigo wearing a hearing aid for the last 1 month. The patient did not have active otorrhea in her otoscopic examination and hennebert test of the patient was evaluated as positive. Cholesteatoma diagnosis was confirmed by high resolution temporal computed tomography and ear magnetic resonance imaging and the operation has been planned. Intraoperatively, the cholesteatoma matrix was removed as a whole on the LSC while the cholesteatoma tissue was cleared. An independent second cholesteatoma matrix was encountered in the defective LSC in the same region.Conclusion: Our case is a case of double cholesteatoma with over-lapping, independent matrix on the LSC, in the same region of the temporal bone.Keywords: Cholesteatoma, middle ear, fistulaPP - 0210 YEARS OF CLINICAL EXPERIENCE IN REVISION STAPEDOTOMY SURGERYEnver Can Öncül1, Yüksel Olgun1, Enis Alpin Güneri1

1Dokuz Eylül University Faculty Of Medicine Department Of Otorhino-laryngology, Izmir, TurkeyObjective: Revision stapedotomy is a surgery that should be done in experienced hands. Different reasons such as reobliteration of the oval window, incus long arm erosion, brits formed around the piston, suspicion of perilymph fistula leads to the need for revision surgery. It can be performed under general or local anesthesia in line with the surgeon’s preference and experience. While general anesthesia provides a more comfortable surgery, local anesthesia is more advan-tageous in detecting labyrinth irritation that may occur during manip-ulation. During revision surgeries, manipulations towards the stapes footplate should be done very gently. In this sense, it is stated that the risk of sensorineural hearing loss is reduced by providing atrau-matic manipulation with the use of a laser. Our study aims to share our experience and results of revision stapedotomy.Materials and Methods: Patients who underwent revision stapedot-omy at Dokuz Eylul University Department of Otorhinolaryngology between January 2011 and October 2020 with a minimum follow-up of 6 months were included in the study. Patients’ demographics, sur-gical characteristics, pre-and postoperative audiological examinations were retrospectively evaluated.Results: 121 Stapedotomy operations were performed in the speci-fied dates. Revision staped surgery was conducted in 12 patients. 7 of them were female, 5 were male and the mean age was 42.8 (20-56).

The mean time between the first surgery and revision surgery was 54.1 (6-252) months. 2 patiens were referred from other centers. The reason for the revision was the absence of closure of the air-bone conduit hearing gap after the first operation in 11 patients, while perilymph fistula was suspected in 1 patient. During revision surger-ies, it was seen that the oval window was re-obliterated in 9 cases, the piston was dislocated in 2 cases, and in one case, it was observed that mobility was restricted due to the brits around the piston. While chorda tympani damage developed in 2 cases during the operation, millimetric perforation occurred in the tympanic membrane in 4 cases and tympanic membrane repair was performed in these cases. Before revision surgery, the mean air-bone gap was 35.3dB and the mean postoperative air-bone gap was 6.58 dB. While the postoperative air-bone gap was between 0-10 dB in 4 patients and between 10-20 dB in 6 patients, it was observed that the air-bone gap was not closed in 2 patients. The mean bone conduction hearing threshold before revi-sion was 28.3 dB, while the average postoperative bone conduction hearing threshold was 29.16dB. No decrease in bone hearing thresh-olds was observed in any patient in the postoperative period.Conclusion: Revision stapedotomy is a rare surgical procedure. In revi-sion surgeries performed carefully by experienced hands, it is possible to obtain successful audiological results similar to primary surgery.Keywords: revision, stapedotomy, reobliteration, oval windowPP - 03A NEW BIOMARKER IN CHRONIC OTITIS MEDIA: THE SYSTEMIC IM-MUNEINFLAMMATION INDEX (SII)Erkan Yıldız1, Selçuk Kuzu2, Çağlar Günebakan2, Aydın Balcı3, Ab-dulkadir Bucak2, Orhan Kemal Kahveci2

Mucosal or Squamous COM differentiation is necessary preoperatively in chronic otitis media patients. The purpose of this study was to test the predictive value of inflammation markers to predict the differentiation of Mucosal COM and Squamous COM. Our aim is; using «SII» as a powerful test to differentiate cholesteatoma and active mucosal middle ear disease.Materials and Methods: In the present study, 300 patients who underwent mastoidectomy±tympanoplasty between 2010 and 2020 were retrospectively evaluated. The patients were divided into two equal groups as clinical, microscopically, and pathologically Squamo-sal COM (Cholesteatoma) and Mucosal COM (Suppurative) (n=150). Routine hemogram tests were performed for both groups. White Blood Cell (WBC), Red Blood Cell (RBC), neutrophil, lymphocyte, and platelet numbers were calculated. The SII value was calculated manu-ally according to the formula of “neutrophil´platelet/lymphocyte.Results: There were a total of 300 patients who were aged 20-63 in both groups. A total of 130 of these patients were male (43%), and 170 (57%) were female. In terms of NLR and PLR, Group 2 (Mucosal COM) had higher values at statistically significant levels (p<0.001, p<0.001, respectively). In terms of SII, Group 2 (Mucosal COM) had higher values at statistically significant levels (p<0.001). According to the results of the ROC Analysis in our series, it was found that

NLR, PLR, and SII values were above the acceptable level, and were statistically significant (p<0.001, p<0.001, p<0.001, respectively). The cut-off value of SII was 470.29, sensitivity was 65.8, and specificity was 34. According to our study, high SII values in COM differentiation are very important in diagnosing Mucosal COM.Conclusion: SII values can help to the diagnosis in Squamous COM/Mucosal COM differentiation. There is no current practical, inexpensive, and widespread laboratory test used in the Mucosal/Squamous COM differentiation. SII can be diagnostic, and determine the treatment in this differentiation. A great number of studies are needed for SII values to become standard in COM.Keywords: Chronic Otitis Media, Cholesteatoma, Inflammation; Neu-trophil-to-lymphocyte ratio (NLR); Systemic Immune-inflammation Index (SII); Mucosal COM; Squamous COM.PP - 04ASSESSMENT OF FALLING RISK IN PATIENTS WITH UNILATERAL PE-RIPHERAL VESTIBULAR DISORDERSBaşak Mutlu1, Merve Torun Topçu1, Sıdıka Cesur1, Mahmut Tayyar Kalcıoğlu2

1Istanbul Medeniyet University, Faculty Of Health Sciences, Depart-ment Of Audiology, 2Istanbul Medeniyet University, Faculty Of Medicine, Department Of Ear Nose Throat & Goztepe Prof.dr. Suleyman Yalcin City Hospital, Ent Clinic, IstanbulObjective: The aim of this study is to determine the relationship be-tween functional and perceptual findings in determining the falling risk of patients with unilateral peripheral vestibular disorders with imbalance.Materials and Methods: Sixty-five patients and 23 healthy controls were included in this study. The participants were administered Dizziness Handicap Inventory (DHI), Falls Efficacy Scale (FES), Dynamic Gait Index (DGI), and static posturography tests. Multiple linear re-gression models were created to predict the FES score dependent variable using DHI, DGI, and static posturography tests independent variables.Results: In this study, patients with Meniere’s disease (7 male, 14 female, age: 45.42±11.41 years), BPPV (7 male, 15 female, age: 57.68±7.47 years), vestibular neuritis (10 male, 12 female, age: 56.22±11.63 years), and healthy controls (8 male, 15 female, age: 49.73±9.5 years) were evaluated. Three regression models were created in which DHI, DGI, and age significantly predicted FES in patients with Meniere’s disease (F(3, 17)=112.511, p˂.001, R2

adjust-

ed=.942), BPPV (F(3, 18)=6.348, p=.004, R2adjusted=.435), and vestibular

neuritis (F(3, 18)=2.73, p=.047, R2adjusted=.322). Significant regression

models in which limits of stability, fall risk, and body sway indepen-dent variables predicted the FES dependent variable could only be created in the Meniere’s disease group. Accordingly, it was found that all risk (F(12, 8)=31.372, p˂.001, R2

adjusted=.948), limits of sta-bility (F(8,12)=7.594, p=.001, R2

adjusted=.725), and body sway (F(11, 9)=11.103, p=.001, R2

adjusted=.847) results significantly affected the FES score.Conclusions: The relationship between static posturography findings and fear of falling in the Meniere’s disease group may be related to in-complete central compensation due to repeated attacks in this group. In determining the risk of falling in pathologies affecting symmetrical vestibular input, it is important to evaluate the static balance with the perceptual methods, to establish an appropriate rehabilitation program.

1Health Sciences University Derince Training And Research HospitalObjective: Progressive necrotizing otitis externa is classically known as malignant otitis externa (MOE) and represents an aggressive in-fection of the external auditory canal (EAC), mastoid, and skull base that can be life threatening. MOE is a uncommon disease, and most patients are elderly and have diabetes mellitus (DM). Here, we report this rare condition with diagnosis, treatment and follow-up manage-ment in our case.Case: A 70-year-old male with type 2 DM presented with persistent otalgia and otorrhea for 3 months. Otoscopic examination re-vealed purulent discharge, severe edema and narrowing of the EAC were observed on the left side. Ear swab was positive for Pseudomo-nas aeruginosa and sensitive to colistin. Computed tomography (CT) shows diffuse fluid and soft tissue densities almost filling the mastoid antrum and mastoid cells and extending to the middle ear. Cortical erosive changes were observed in the mastoid bone and anterior part of EAC. Also, fungus ball was observed in the left sphenoid sinus on CT and endoscopic sinus surgery was performed. The patient received antibiotic therapy with colistin (100 mg every 12 hours) for 4 weeks and fluconazole for 2 weeks (100 mg every 24 hours), hyperbaric ox-ygen therapy and surgery. The procedure was a left radical mastoid-ectomy. The patient’s clinical symptoms almost completely resolved but he was referred to the algology unit as his ear pain complaint continued.Conclusion: Misdiagnosed MEO can involve the skull base and cause major complications such as thrombosis of the lateral sinus or inter-nal jugular vein, meningitis, Bezold’s abscess, and cranial nerves pal-sies (3). Patients with MEO often present with otalgia, which can be associated with temporal and occipital headache, otorrhea, edema, and granulation tissue, such as in our experience (4). In the literature, there is no a standardized protocol for management of MEO. Surgical debridement, hyperbaric oxygen and systemic antibiotic therapy are the main parts of the treatment. Also, fungal agents should be con-sidered and systemic antifungal should be added to therapy in cases where antibiotic-resistant and no growth in culture.(5)Keywords : malign,otitis,diabeticPP - 07NECROTIZING OTITIS EXTERNA MANAGEMENT IN THE PERIOD OF COVID 19 PANDEMICSümeyye Bozkuş1

1Kocaeli University Research HospitalObjective: Necrotizing otitis externa is a serious infection affecting the external auditory canal and the temporal bone. Prolonged parenteral antibiotics are required and inadequate treatment courses may result in disease. It is more difficult to follow patients in the period of Covid 19 pandemic. Materials and Methods: We report in this retrospective study. We followed up two patients with necrotizing otitis externa in 2019-2020 who were diabetic. Results: All 2 patients had evidence of bony erosion on computed tomography of the temporal bones. All 2 patients required mastoid-


ectomy and undergo daily microdebridements and intravenous anti-biotic therapy that third generation cephalosporin , fluoroquinolone, carbapenem, oxazolidinone, aminoglycoside, teicoplanin, piperacillin/tazobactam. First patient had CN 7 palsy and had improved left side sigmoid venous thrombosis, meningitis, osteomyelitis. Second patient had improved abscess in parotid space. First patient died due to right MCA infarct, second patient treated successfully.Conclusion: Follow up of patient with necrotizing otitis externa is a hard situation during Covid 19 pandemic. Early diagnosis and prolonged therapy are more difficult due to excessive inpatients at hospital in the period of Covid 19 pandemic. Our patients didn’t want to stay in hospital while Covid 19 cases increased. Mortality of this disease increases because of impairment of treatment process.Keywords: Otitis Externa, drug therapy, Otitis Externa, Osteomyelitis, diagnostic imagingPP - 08НEARING FUNCTION IN PATIENS WITH AUTOIMMUNE THYROIDITIS DUE TO DPOAE AND ABR`S DATAMaksym Tarasenko1, Yulia Dieieva1, Naumenko Aleksandr1

1Bogomolets National Medical UniversityThe function of the outer hair cells (OHC) in patients with euthyroid autoimmune thyroiditis (AIT) was investigated in frequency range of 1000 - 8000 Hz. Our aim was to measured of AIT factors influence on auditory function in patients with no subjective sensations of hearing loss. For this study we selected patients with euthyroid AIT. Patients average age on 33,25 ± 6,32 years. The main group consisted of 59 people. The control group was presented by 29 relatively healthy individuals, without AIT and normal hearing function. Each patient was determined the levels of thyroid stimulating hormone (TSH), free thyroxine (T4), free triiodothyronine (T3), thyroid peroxidase antibod-ies (TPAb), thyroglobulin antibodies (TGAb). The function of the outer hair cells (OHC) of the inner ear was assessed by the registration of distortion product otoacoustic emission (DPOAE) and auditory brains-trem response (ABR) evaluation. We estimated dependency of DPOAE data on TPAb and TGAb levels in the patients’ blood tests. We used program Statistical Package for the Social Sciences 17 for statistical data. In the study of dependency between DPOAE and ABR`s data and TPAb, TGAb levels we indicated a statistically significant correlation between increased activity of autoimmune process and decrease OHC function in the frequency range of 5714 - 8000 Hz.Keywords: autoimmune thyroiditis, sensorineural hearing loss, oto-acoustic emission, auditory brainstrem response, statistical analisis.PP - 09TRANSMASTOID REPAIR OF TEGMEN DEFECTS DUE TO TRAUMAEmine Deniz Gözen1

1Istanbul Universty Cerrahpasa- Cerrahpasa Medical Faculty- Otolar-yngologyObjectives: Cerebrospinal fluid (CSF) leakage from the temporal bone occurs due to rupture of the arachnoid membrane or herniation of the brain. According to the size of the defect only arachnoid may herniate, or brain tissue may accompany herniation.The purpose of this study is to review the clinical presentation, surgi-cal techniques, and outcomes of the transmastoid extradural– intra-cranial (TMEDIC) approach for the treatment of CSF leakage from the temporal bone.Materials and Methods: Clinical data, imaging results and surgical findings for 2 patients presenting with CSF leakage originating in

the temporal bone were reviewed. In the preoperative period both patients were evaluated by HRCT of the temporal bone and in one patient MR cisternography was also performed. Age, gender, side, presentation and etiologic factors were analyzed.Results: Average age was 44 years. Both of the patients were female. In patient 1 the effected side was right ear and the etiology of the CSF leakage was previous surgery due to COM with cholesteatoma. In patient 2 the CSF otorrhea was from the left ear and was due to temporal bone fracture following trauma. Patient 1 presented with ear discharge and in otomicroscopy pulsatile mass was detected in the mastoidectomy cavity. Patient 2 presented with ear fullness and rhinorrhea and physical examination revealed intact tympanic mem-brane with effusion within the middle ear cavity. In Patient 1 HRCT revealed bony defect in the tegmen mastoidea with approximately 2 cm meningocele. The CT imaging of Patient 2 demonstrated defect in tegmen tympani with soft tissue inside the middle ear. MR cister-nography was performed which demonstrated CSF leakage from the tegmen defect draining through the Eustachian tube. Both of the patients were operated on through transmastoid approach and no intraoperative or postoperative complications were detected. Patients were followed up for up to 5 years and recurrence was not detected.Surgical Procedure:Patient 1:Under general anesthesia retroauricular incision was per-formed and previous radical mastoidectomy cavity was visualized. Following enlargement of the mastoidectomy cavity meningocele extending from approximately 2 cm tegmen defect was seen. The meningocele was reduced with the help of bipolar cautery. With blunt dissection the dura was elevated approximately 0.5 cm from all sides and 3 layered plugging was performed.Patient 2:A standard postauricular mastoidectomy was performed. Under high magnification the fracture was detected in tegmen. A small dural defect was seen and active CSF drainage was detected. Following blunt dissection of the dura off the surrounding bone 3 layered obliteration was performed. Conclusion: The TMEDIC is a safe and effective method to repair CSF leakage from the temporal bone preventing the need for a middle fossa craniotomy in certain cases.Keywords: tegmen defect, temporal bone, cerebrospinal fluid leak-age, mastoidectomyPP - 10HEARING LOSS IN COVİD-19Emrah Gülmez1

1Fethi Sekin City HospitalHearing loss has a vital role in speech and communication and can cause an invisible handicap of the affected person and psychological solitary confinement.The association between the COVID-19 infection and sudden sen-sorineural hearing loss makes intuitive sense, given the neuropathic manifestations of the inner ear and auditory nerve. Although certain viral infections cause hearing loss, there is still unknown whether COVID-19 infection leads to auditory dysfunction or not. COVID-19 infection is highly contagious and seen in the respiratory system due to the novel virus SARS-CoV-2.Viral infection has been associated with sudden sensorineural hearing loss (SSNHL). Inflammation of the auditory pathway, including cochle-ar nerve, cochlea, and perilymphatic tissue, as well as cross-reaction between the antigens in the inner ear and virus have all been linked as the culprit in causing SSNHL. Additionally, indirect virus transmis-

sion from cerebrospinal fluid to the inner ear structures can also ex-plain the cause behind SSNHL.Kilic et al. studied five Turkish male patients with the sole complaint of unilateral SNHL who visited their otolaryngology outpatient clinic in April 2020 and found that one of the patients was COVID-19 pos-itive. Another case report of a 60-year-old COVID-19 patient with hyperactive delirium who developed bilateral deafness with tinnitus confirmed by acoustic evoked potential after his delirium resolved. Audiologic testing revealed complete deafness on the right side and profound sensorineural hearing loss on the left side. MRI demonstrat-ed a partially decreased fluid signal in the cochlear basal turn of the right cochlea and a pronounced contrast enhancement in the right cochlea. In addition, meningeal contrast enhancement was observed at the base of the right temporal lobe adjacent to the temporal bone. A common practice is the use of systemic corticosteroids as initial therapy for SNHL. Neither of the two latter cases used systemic corti-costeroid therapy, rather intratympanic triamcinolone injections and COVID-19 treatment were utilized.It is now important that hearing loss needs to be investigated among patients positive for SARS-CoV-2 infection and especially the patients who have recovered from SARS-CoV-2 infection as the possibility of permanent hearing loss cannot be ignored.COVID-19 should be taken into consideration in patients presented with sudden hearing loss nowadays. Much work up for understanding the pathogenesis and auditory complications of this challenging dis-ease still extremely needed next days.Keywords: COVID-19, sensorineural hearing lossPP - 13PEDIATRIC LANGERHANS CELL HISTIOCYTOSIS OF THE TEMPORAL BONEFatma Gülüm Ivgin Bayraktar1, Sema Zer Toros1, Selim Kul1, Çiğdem Tepe Karaca1

1Haydarpaşa Numune Education And Research HospitalObjective: Langerhans cell histiocytosis(LCH) is a disease originated from clonal abnormal proliferation of Langerhans cells.It can affect any organ or system.50-80% of LCH is found in head and neck site and in app.15-60% of these cases,temporal bone is affected.Case: A 6 years old boy presented our emergency with a 3-week history of right postauricular pain and swelling resistant to antibiotic treatment.According to physical examination there was right mastoid tenderness and otoscopic examination was normal.Ultrasonographic evaluation showed dense collection in postauricular region.Temporal CT scan showed opacification of mastoid air cells,coalescent mas-toiditis and suspicious posterior cranial involvement.MRI venography showed an indent on the inferior part of sigmoid sinüs due to the mass effect of the disease.The patient is indicated for surgery due to the osteolytic lesion on the temporal bone.We performed cortical mastoidectomy and postoperative pathology revealed Langerhans cell histiocytosis as a diagnosis.Conclusion: Most of the otologic diseases can present with mastoid-itis,mastoid abcess or postauricular swelling.So we can easily misdi-agnose LCH.In the presence of osteolytic defect in temporal bone,we have to suspect for LCH since majority of the cases respond to sur-gery,radiation,chemotherapy or combination therapy.

PP - 14GIANT SQUAMOUS CELL CARCINOMA OF THE EXTERNAL AUDITORY CANALFelat Toprak1

1Ankara Abdurrahman Yurtaslan Oncology Education And Research HospitalObjective: Temporal bone malignancies are rare cancers. With this case, we aimed to present the clinical approach to the squamous cell carcinoma of the external auditory canal.Case: A 68-year-old female patient applied to our clinic with an ulce-rovegetative mass that destroyed the right auricula and the skin of the right neck. She received radiation therapy to the right auricular region 40 years ago for non-malignant skin disease in another clinical center abroad. Temporal bone CT and face/neck MR images of the patient who was diagnosed with squamous cell carcinoma (SCC) as a result of incisional biopsy were examined. The patient was decided to operate. The patient underwent total excision of the mass, total parotidec-tomy, type 2 modified radical neck dissection, subtotal temporal bone resection, and the skin defect was repaired with the right pectoralis major flap. The postoperative pathology was assessed as T3N0M0 and the perineural or lymphovascular invasion was not present; as the 3rd stage SCC of the external auditory canal, adjuvant RT was decided. No recurrence or complication was observed in the patient who came to the controls after RT in the third month.Conclusion: Although temporal bone malignancies are rare, it is diffi-cult to achieve total resection in advanced cases due to the adjacent vital structures. The general approach in the treatment of the disease is surgery; adequate data should be collected about the resectability of the mass and additional surgical procedures to be performed by the preoperative physical examination and radiological imaging.Keywords: Squamous cell carcinoma, External Auditory Canal, Tempo-ral bone cancerPP - 16MULTIPLE DEHISCENCE ASSOCIATED WITH AN ENLARGED HIGH-RID-ING JUGULER BULB: A CASE REPORTSüreyya Hikmet Kozcu1, Sinan Uluyol2

1Yatağan State Hospital 2Private Ent ClinicObjective: The posterior semicircular canal dehiscence (PSCD) which can cause many audio-vestibuler symptoms is a rare clinical manifes-tation. Its diagnosis is challenging due to its overlapping symptom-atology and the absence of predisposing factors previously defined. A case of multiple dehiscence (PSCD, facial canal dehiscence, and mid-dle ear dehiscence) associated with an enlarged high-riding jugular bulb is presented.Case: A 55 year old male presented with longstanding complaints of right-sided autophonia, aural fullness, pulsatile tinnitus and hearing loss. There was no other audiovestibular complaint and no other symptoms related to the facial nerve. In addition, he did not suffer from facial paresis or hemifacial spasm. In micro-otoscopy, normal eardrum and ventilated middle ear were observed in both ears. No vestibular phenomenon was seen when loud sound or by pressure exerted in the external auditory canal. On both ear, impedance testing was normal and stapes reflexes were positive. Audiometric evaluation revealed a mild down-sloping sensorineural hearing loss on the left side and a moderate down-sloping mixed-loss pattern on the right side. The bone conduction hearing thresholds and word recognition scores were bilateral equal. High-resolution CT (HRCT) of the temporal bones was performed (0.75 mm thick reformatted in axial, and coronal planes). HRCT images demonstrated an enlarged right-sided HRJB (measuring 2.01 cm in largest diameter) eroding into the posterior semicircular canal, mastoid segment of the facial canal, and middle ear causing bony dehiscence (Fig 1 – 3). No dehiscence was seen in the other semicircular canals or anatomical subsides, bilaterally. Surgical treatment and its complications were explained to the patient. Proposal of possible amplification was done. However, no intervention was accepted by the patient.


Conclusion: Semicircular canal dehiscence may be seen in all semi-circular canals. Each canal dehiscence is associated with different causes.1 PSCD is the least common among all semicircular canal dehiscences and it is most frequently associated with juguler bulb abnormalities.2,3 To our knowledge, it is very rare for a case to have facial canal and middle ear dehiscence in addition to PSCD.3 While no symptoms may be observed in patients with PSCD, various third window symptoms (conductive hearing loss, vertigo and oscillopsia developing after exposure to pressure and sound, etc.) can also be seen.1,4 Additionally, these symptoms may be present making its differentiation from other otologic problems important.5 Although, HRCT remains gold standard for diagnosis of PSCD, audiometry, im-pedancemetry, and stapes reflex measurement, vestibular evoked myogenic potential (VEMP) testing, and MRI are used in differen-tial diagnosis.3 Surgical treatment has been defined, and possible amplification or clinical follow-up is also recommended by different authors.3,6,7

1Kütahya Health Sciences University Faculty Of Medicine, Department Of Otorhinolaryngology Head And Neck Surgery, Kütahya, Turkey; 2Kütahya Health Sciences University Faculty Of Medicine, Department Of Pathology, Kütahya,turkeySalivary gland ductal carcinoma is a rare, fast-growing, painful, ag-gressive, poor prognosis tumor that usually occurs between the ages of 60-65. It is most commonly seen in the parotid gland, but it may rarely arise from the minor salivary glands. Intraparotitis microcalcifi-cations, pain and facial paralysis are findings that support the diagno-sis of ductal carcinoma. Histopathologically, it is similar to infiltrative ductal carcinoma and prostatic carcinomas of the breast. Distant me-tastasis rate ranges from 40% to 60%. The most effective treatment of ductal carcinoma of the parotid gland, often accompanied by facial paralysis, is surgery and radiotherapy.Case: A 77-year-old male patient was admitted to our clinic with complaints of swelling and pain in the left preauricular region and auricle for 6 months. On examination, a 4.5x3.5 cm hard, fixed mass with irregular borders was found extending from the left preauric-ular region to the auricle and external auditory canal. Fine needle aspiration cytology revealed malignant epithelial tumor. The patient underwent total parotidectomy, functional neck dissection, and par-tial auricular excision. Postoperative histopathological examination was reported as parotid gland ductal carcinoma. No recurrence was observed in the 8-month follow-up of the patient, who was referred to the oncology clinic for postoperative radiotherapy.Keywords: Auricula ,ductal carcinoma,parotid gland,salivary glands
