徒手整復術が有効であった披裂軟骨後方脱臼例 A Case Report of Arytenoid Dislocation Treated by Manually Closed Reduction
Arytenoid dislocation is relatively rare among traumatic laryngeal disorders. It can be caused by traffic accidents or endotracheal intubation, and the incidence appears to be increasing. We report a case of arytenoid dislocation associated with insufficient glottal closure caused by endotracheal intubation. The patient was a 67-year-old woman who underwent total gastrectomy under general anesthesia. Hoarseness was noted immediately after surgery and it continued for a week postoperatively. Fiberscopic examination revealed restricted adduction of the left vocal cord and CT scan indicated posterior dislocation of the left arytenoid. The case was treated by manually closed reduction, with obvious improvement in glottal closure.
