ANTERIOR ARYTENOID DISLOCATION THAT DEVELOPED AFTER ESOPHAGOGASTRODUODENOSCOPY: A CASE REPORT

Abstract

A 72-year-old man visited our hospital to undergo esophagogastroduodenoscopy (EGD) for epigastric pain. Following EGD, he developed hoarseness, which persisted even after four days; therefore, we referred him to an otolaryngologist. Laryngoscopy revealed anterior dislocation of the left arytenoid cartilage, with a flaccid and shortened left vocal cord. Maximum phonation time was remarkably reduced to 3 seconds. Computed tomography findings were normal. Arytenoid dislocation caused by EGD was diagnosed. The patient underwent noninvasive reduction under general anesthesia.
