title: Vocal process avulsion.
abstract: Vocal process avulsion is a rare condition in which laryngeal trauma causes a separation of the vocal process from the body of the arytenoid cartilage. Typically symptoms are dysphonia and shortness of breath during phonation. Strobovideolaryngoscopy, laryngeal electromyography, and laryngeal computed tomography are helpful in establishing this important and sometimes elusive diagnosis. Several treatment modalities have been reported with varying success. We report four new cases, review four cases reported previously by the senior author, and suggest approaches to diagnosis and optimal treatment of vocal process avulsion.
