ntroduction
n the past decade, we have witnessed the introduction andissemination of transoral robotic surgery for the treatmentf tumors, mainly of the oropharynx and larynx. The use ofobotic surgery improves visualization of the operative fieldue to its three-dimensional image and enhances the sur-eon’s dexterity due to bimanual control of the robotic arms.urthermore, the assistant contributes with suction and tis-ue traction, which leads to the use of four instrumentsuring surgery, something impossible during a transoralesection through laryngoscopy, for instance.1 Therefore,

he technique makes the approach truly minimally invasive,specially in the case of supraglottic partial laryngectomy,n which the conventional open approach inevitably leadso protective tracheostomy and feeding tube use, some-imes for prolonged periods. The robotic access, however,llows for early feeding without the need of a tube, andlso eliminates the need for tracheostomy in many cases,s the rates of aspiration, fistulas, or other complicationsre significantly reduced when compared with conventionalurgery and with oncologic and functional results that areuite similar between the two techniques.2
Therefore, this study reports the first case of supraglotticartial laryngectomy performed by transoral robotic surgeryn Brazil, as well as documents the late oncologic and func-ional results (Approved by the Research Ethics Committeender No. 228/14).

57-year-old female patient was evaluated for a fouronth complaint of odynophagia; she was a long-term

cervical lymph nodes. The nasofibrolaryngoscopy identifieda large vegetating lesion affecting the entire epiglottis andextending to the left aryepiglottic fold, but not affecting thearytenoid fold or the left ventricular fold; both vocal foldswere still mobile.
An incisional biopsy revealed that the lesion was amoderately differentiated squamous cell carcinoma (SCC).Assessment by computed tomography (Fig. 1) showed thatthe lesion had limits compatible with the laryngoscopy, with-out pre-epiglottic space involvement and without cervicallymph nodes suggestive of metastases. There was no evi-dence of pulmonary metastases; the search for a secondprimary tumor through high digestive endoscopy with chro-moendoscopy was negative, and the cancer was staged asT2N0M0 (stage II).
The patient then underwent a transoral robotic supra-glottic partial laryngectomy using the daVinci SI SurgicalSystem® (Intuitive Surgical®; Sunnyvale, California, UnitedStates) equipment (Fig. 2). The procedure was uneventful,lasted 158 minutes, had a 50-mL blood loss and the resectionhad clear intraoperative frozen section margins. There wasno need for tracheostomy and the patient was extubated inthe operating room under endoscopic view. Also, the useof a parenteral feeding tube was not necessary, and thepatient received a thickened liquid diet on the second post-operative day, without evidence of aspiration. The lengthof hospital stay was three days. Definitive anatomopatho-logical analysis disclosed a moderately differentiated SCCwithout perineural or angiolymphatic invasion with marginsfree of tumor.
After 24 postoperative days, the patient underwentuneventful selective cervical dissection of levels II, III, andIV bilaterally and histopathological analysis found no metas-tases in 57 dissected lymph nodes; she was discharged within72 hours.
There was no indication for adjuvant treatment, and thepatient remains on outpatient follow-up, with no evidenceof disease, with a normal diet and no voice alterations at 42months of follow-up.
Discussion
Since the first published work by Weinstein in 20073 withthe description of the first three cases, other centers began

o perform supraglottic laryngectomy using the transoralobotic approach, but the number of reported cases is stillow. The largest series in the literature included 84 surgerieserformed in seven French services.1 The authors demon-trated that the mean time of parenteral tube use wasight days and 24% of patients resumed oral intake 24 hoursfter the procedure. Only 24% of patients required a tra-heostomy, but there was aspiration pneumonia in 23% ofases, including one death for that reason. Postoperativeleeding occurred in 15 patients and 51% of the patientsequired adjuvant radiotherapy due to the anatomopatho-
ogical findings, but there is no description in this study ofhe oncologic outcomes in these patients.Therefore, a systematic review in the Medline databasentil September 2015 (using the key words [‘‘laryngectomy’’

nd ‘‘robotic surgery’’]) was performed, and it retrieved 11rticles,1,3---12 totaling 176 cases, in addition to the patienteported herein (Table 1). It was observed that most of thencluded patients had tumors at an early stage (stages I andI) and that the surgery was performed with free marginsn most cases, with few complications. The need for tra-heostomy and a parenteral feeding tube was variable, butrief, in most cases. The need for adjuvant therapy was lownd oncologic results showed no cases of local recurrence,emonstrating the safety of the method.
In this case, some aspects are noteworthy and were latererified by other studies summarized here: the patient hadn uneventful postoperative period, in addition to very sat-sfactory oncologic and functional results. The desire torovide the patient’s late follow-up status led to the delayn reporting the present case.
onclusion
his case describes the viability of supraglottic partialaryngectomy by transoral robotic approach, with good post-perative evolution and early rehabilitation. It is therefore aafe method, with very satisfactory oncologic and functionalesults.
