A Case of Mutational Dysphonia Treated with Type III Thyroplasty
제 3 형 갑상연골성형술에 의한 변성발성장애의 치험 1례
Abstract
Type III thyroplasty is a useful surgical procedure reducing the tension of vocal cords by removing the vertical strip of anterior thyroid cartilage and resuturing the cut ends. One of the indications for this procedure is mutational dysphonia, the disease of men who has a childlike vocal pattern even after the process of puberty. We have experienced one case of mutational dysphonia treated with type III thyroplasty. He had high pitched voice from the middle school age and his preoperative fundamental frequency was 272.35 Hz. Two months after the surgery. the fundamental frequency was 129.58 Hz and the patient was also subjectively satisfied with his low-toned voice.
