성전환 수술을 받은 환자에서의 Pitch Elevation 술식 1례

Laryngeal framework surgery to improve change the voice is a challenging development in phoniatric surgery. Basically two categories can be distinguished : (1) attempted medialization of the vocal fold, as for the treatment of paralytic dysphonias (2) adjustment of the vocal fold's tension of transsexuals or mutational dysphonia. Vocal pitch can be elevated by various surgical technique 1) cricothyroid approximation 2) A-P expansion of the thyroid ala 3) longitudinal incision in the cords 4) intrachondral injection of the steroid, and 5) evaporation of the cords by $CO_2$ laser. We have experienced a case of pitch elevation procedure after transsexual operation. After transsexual operation, he had received anterior commissure laryngoplasty modified from Le Jeune with no change in voice pitch(Fo=110Hz). 8 monthes later, he had received cricothyroid approximation resulting in pitch elevation(Fo=160Hz).
