Endotracheal intubation, a relatively safe procedure, is widely used with the development of anesthetic technique, but inflammation, edema, ulceration, and granuloma on the vocal cord are occasionally reported. Vocal cord paralysis after endotracheal anesthesia following surgery not involving the vagus nerve is extremely rare, and stretching and pressure on the nerve are considered to be possible causes. Recently the following case was seen and treated by our staff. Bilateral vocal cord paralysis had developed immediately after extubation of the endotracheal tube, in a 42 year old male patient who was admitted to the hospital for primary closure of duodenal ulcer perforation. The right cord paralysis completely recovered after 45 days postop. and the left cord paralysis completely recovered after 107 days postop. We report this case with review of literatures.
