Arytenoid dislocation is one of the rare but serious complications of endotracheal intubation. A 43-year-old healthy man was admitted for total ossicular replacement prosthesis with canal down mastoidectomy. Anesthesia was induced and direct laryngoscope guided endotracheal intubation was done with a cuffed endotracheal tube sized of internal diameter of 7.0 mm. The trachea was extubated without any difficulty after surgery. About 5 hours later, the patient complained of sore throat and hoarseness. On the 16th day after the operation, he visited the clinic and complained of continuing of hoarseness. Direct laryngoscopy revealed anterior and inferior dislocation of left arytenoid cartilage. On the 30th day after the operation, the patient was taken to the operating room for reduction of the dislocated cartilage by the otolaryngologist. The reduction was done successfully and the patient\'s hoarseness gradually resolved.
