AbstractA previously healthy 39-yr-old man was scheduled for exploratory laparotomy due to acute abdomen. There was no sign of difficult intubation. After induction of anesthesia with thiopental and succinylcholine, the trachea was easily intubated with a 7.0 mm cuffed endotracheal tube. Surgery for a ruptured appendix with 2 drainage tubes lasted for 75 min was uneventful. At the end of surgery, the endotracheal tube was removed without difficulty. On the 1st postoperative day, the patient developed stridor. The symptom persisted even after conservative treatment and removal of NG tube. On the 12th postoperative day, a telescopic videolarygoscopy revealed immobile right vocal cord with anterior and medial displacement to the right. Arytenoid cartilage was moderately edematous. A diagnosis of right arytenoid subluxation was then made. On the 17th postoperative day, a closed reduction of right arytenoid cartilage using direct laryngoscope was performed successively under general anesthesia. Eight weeks after the reduction, his voice and laryngoscopic findings were normal. There has been only 18 reports with 27 cases of this complication found in the literature. However, it is generally believed that it is not so unusual. The post-intubation syndromes, such as sore throat, dysphonia, odynophagia, difficulty in swallowing or breathing which persists beyond 5 days warrant ENT consultation. Abnormal mobility of vocal cord, edema over arytenoid area found by indirect laryngoscopy should suggest the complication. Further confirmation is then needed. Although the result of our case is good, the reduction should ideally be done within 24-48 h after the incidence to avoid unfavorable long-term sequelae.
