The transgender is who has persistent discomfort with his of her sex or sense of inappropriateness in the gender role of that sex. Many transgenders have been undergone trans-sex operations after 1980's. But there were not so much experience of voice surgery for transgenders. Vocal pitch can be elevated by various surgical techniques. Type IV thryoplasty, which one of the cricothyroid approximation methods, increases tension to the vocal folds, thus increasing fundamental frequency and upper pitch range. We treated a transgender (MTF, Male to female) using this technique. Acoustic and aerodynamic measures were obtained both pre- and post-operatively. Clinically significant improvement was achieved in both study; increasing of vocal pitch, widening of pitch range, and improvement of vocal efficiency.
