Arytenoid dislocation after uneventful endotracheal intubation

ryngeal morbidity, such as hoarseness, submucosal hemorrhage, subglottic edema, laryngitis, and arytenoid cartilage dislocation [1,2]. Among others, hoarseness is reported as the most common laryngeal morbidity after general anesthesia, with widely varying incidence from 16% to 55% [3]. However, it is generally resolved within a few days, unless accompanied by serious complications, such as arytenoid dislocation [3]. The arytenoid cartilages are a pair of small 3-sided pyramids that form part of the larynx, to which the vocal cords are attached. Arytenoid dislocation is an unusual complication after external trauma or endotracheal intubation; its incidence is < 0.1% when associated with intubation [4]. Iatrogenic arytenoid dislocation is occasionally reported in cases with difficult intubation, double lumen endotracheal tube intubation, or intubation with a stylet [5,6]. However, we experienced a case of arytenoid dislocation despite easy and uneventful intubation. Therefore, we reported this case along with a review of related literature.
