Abstract
Bilateral thyroarytenoid myectomies were performed on 14 patients with adductor spasmodic dysphonia. During the operation bleeding was controlled by use of a Laser. Fat tissue was removed from abdomen and inserted into vocal fold to fill in the defect after myectomy procedures and to prevent scarring. The patients' voices were restored to normal without recurrence of dysphonia. This operation is one of the most effective treatment for adductor spasmodic dysphonia.
