Abstract
|
|
|
|
Arytenoid cartilage dislocation is one of the most common mechanical causes of vocal fold immobility. The most common etiologies are intubation and external trauma, but its incidence is lower than 0.1%. Its symptoms include dysphonia, vocal fatigue, loss of vocal control, breathiness, odynophagia, dysphagia, dyspnea, and cough. Although there are some reports of arytenoid cartilage dislocation in adults, there are only few reports on its occurrence in children. It is particularly difficult to detect the symptoms of arytenoid cartilage dislocation in uncooperative pediatric patients with brain lesions without verbal output or voluntary expression. We report a case of arytenoid cartilage dislocation with incidental findings in a videofluoroscopic swallowing study performed to evaluate the swallowing function.
