Thyroplasty was performed under local anesthesia on male-to-female transsexuals (MTF/GID) as well as patients with adductor spasmodic dysphonia (AdSD). There were 31 patients with MTF/GID who underwent type 4 thyroplasty during the period from 1999 to 2006. Voice fundamental frequency (F0) rose in all patients. Mean preoperative F0 was 135Hz, and postoperatively the mean value was 236Hz. Type 4 thyroplasty requires specialized skill, and was found to be effective for pitch elevation surgery in MTF/GID. Forty-one patients with AdSD underwent type 2 thyroplasty with Titanium Bridge between December 2002 and December 2005. These patients were followed up 1 year postoperatively with a questionnaire. 70% of the patients judged their voice as "excellent, " and the remaining patients as improved to "good" or "fair". Type 2 thyroplasty is a highly effective therapy for AdSD.
