• Synonym: Nasopharyngeal tonsil
• Adenoids is the hypertrophied mass of lymphoid tissue situated at the junction of roof & post. wall of nasopharynx.
• The mass of lymphoid tissue is termed as Adenoids only when it is hypertrophied.
• It usually undergoes atrophy by puberty (13-14 yrs)

Adenoidectomy
![Page 17: Adenoids](https://reader035.vdocuments.mx/reader035/viewer/2022081502/55398eb74a7959016b8b4a5a/html5/thumbnails/17.jpg)
Indications :
1. Adenoid hypertrophy causing snoring, mouth breathing, sleep apnoea syndrome or speech abnormalities, i.e. (rhinolalia clausa).
2. Recurrent rhinosinusitis.
3. Chronic secretory otitis media associated with adenoid hyperplasia.
![Page 18: Adenoids](https://reader035.vdocuments.mx/reader035/viewer/2022081502/55398eb74a7959016b8b4a5a/html5/thumbnails/18.jpg)
4. Recurrent ear discharge in benign CSOM associated with adenoiditis/adenoid hyperplasia.
5. Dental malocclusion. Adenoidectomy does not correct dental abnormalities but will prevent its recurrence after orthodontic treatment.

Contraindications :
1. Cleft palate
2. Haemorrhagic diathesis.
3. Acute URTI

Anaesthesia :
• Always general, with oral endotracheal intubation.

Steps of Operation :
1. Boyle-Davis mouth-gag is inserted. Before actual removal of adenoids, nasopharynx should always be examined by retracting the soft palate with curved end of the tongue depressor and by digital palpation, to confirm the diagnosis, to assess the size of adenoids mass and to push the lateral adenoid masses towards the midline.
![Page 23: Adenoids](https://reader035.vdocuments.mx/reader035/viewer/2022081502/55398eb74a7959016b8b4a5a/html5/thumbnails/23.jpg)
2. Proper size of "adenoid curette with guard" is introduced into the nasopharynx till its free edge touches the posterior border of nasal septum and is then pressed backwards to engage the adenoids. At this level, head should be slightly flexed to avoid injury to the odontoid process.

3. With gentle sweeping movement, adenoids are shaved off . Lateral masses are similarly removed with smaller curettes; small tags of lymphoid tissue left behind are removed with punch forceps.
4. Haemostasis is achieved by packing the area for sometime. Persistent bleeders are electro-coagulated under vision. If bleeding is still not controlled, a postnasal pack is left for 24 hours.

Endoscopic Adenoidectomy
• These days adenoids can be removed more precisely by using a debrider under endoscopic control

Coblation adenoidectomy
• It is also other wise known as cold
abalation. This technique utilises a field of plasma, or ionised sodium molecules, to ablate tissues. The heat generated varies from 40 - 80 degrees centigrade, much lower than that of electro cautery. The major advantage of this procedure is reduced bleeding and reduced post operative pain.

Post-operative Care :
1. Immediate general care
(a) Keep the patient in coma position until fully recovered from anaesthesia.
(b) Keep a watch on bleeding from the nose and mouth.
(c) Keep check on vital signs, e.g. pulse, respiration and blood pressure.
![Page 36: Adenoids](https://reader035.vdocuments.mx/reader035/viewer/2022081502/55398eb74a7959016b8b4a5a/html5/thumbnails/36.jpg)
Post-operative Care cont..
2. Diet When patient is fully recovered he/she is to
take liquids, e.g. cold milk or ice cream.
3. Nasal saline drops
![Page 37: Adenoids](https://reader035.vdocuments.mx/reader035/viewer/2022081502/55398eb74a7959016b8b4a5a/html5/thumbnails/37.jpg)
Post-operative Care cont..
4. Analgesics : I/V or oral
5. Antibiotics : Orally or I/V for a week.
Patient is usually sent home 24 hours after
operation unless there is some complication. Patient can resume his normal duties within 2 weeks.

Complications :
1. Haemorrhage
2. Injury to eustachian tube opening
3. Injury to pharyngeal musculature and vertebrae
4. Griesel syndrome. Patient complains of neck pain and develops torticollis. Mostly it is due to spasm of paraspinal muscles, but can be due to atlanto-axial dislocation requiring cervical collar and even traction.
