概要

Spastic dysphonia is a severe voice disorder apparently due to extreme tension of the entire phonatory system. It is rather rare in Japan. Psychotherapy, speech therapy, and many other forms of conservative therapy for spastic dysphonia have so far been disappointing. Thyroplasty type II (antero-posterior shortening of the thyroid cartilage) was performed on a patient with spastic dysphonia and the results were satisfactory.Thyroplasty type II has the effect of relaxing the tension and abducting the vocal cord slightly. The surgical procedure required is rather simple, easy to perform, and unaccompanied by complications.The advantages of our surgery are summarized as follows:1) There is no direct surgical intervention on or in the vocal cord or the recurrent laryngeal nerve.2) Operation is performed under local anesthesia and with the use of a laryngeal monitor system.3) It is an easy surgical procedure and has almost no postoperative complications.
