A right arytenoid deolaction resrlted from general anesthesia / 대한마취과학회지

Arytenoid cartilage dislocation is a very rare complication of endotracheal intubation. This change can occur as a result of compressing the cryco-arytenoid joint by inflated cuff of endotracheal tube. A 21-year old male, ASA physical status I with chronic otitis media underwent tympanoplasty with mastoidectomy. Anesthesia was induced with thiopental-succynylcholine and was maintained with nitrous oxide-oxygen-enflurane. On the first postoperative day, the patient complained of hoarseness, and on the second postoperative day, the right arytenoid was found dislocated under indirect laryngoscopy. Five days postoperatively, endoscopic reduction was performed under direct laryngoscopy, thereafter his symptom gradually disappeared.
