Summary
Thyroarytenoid muscle avulsion is a rare condition in which laryngeal trauma causes
a separation of the thyroarytenoid muscle from the arytenoid cartilage. Typically,
symptoms are nonspecific but include severe dysphonia and voice fatigue. They are
similar to symptoms of vocal process avulsion. Strobovideolaryngoscopy, laryngeal
electromyography, and laryngeal computed tomography may be helpful in diagnosis. However,
intraoperative palpation under general anesthesia is the most definitive way to establish
its diagnosis. We present two cases of thyroarytenoid muscle avulsion, a condition
that has not been described previously. Surgical techniques for repair are detailed.
