Description

We herein report on the long-term voice quality after autologus fat injection of the vocal fold. We evaluated 11 patients in whom more than six months had passed since being operated on. We inject autologus fat into thyroarytenoid muscle. We perform this method for voice insufficiency because of vocal cord atrophy and vocal cord paralysis. After performing the injection, voice quality was found to improve, and the voice quality was thereafter maintained for a long time in an acoustic and aerodynamic analysis. We therefore think that autologous fat injection in the vocal cord is good and reasonable method for the treatment of voice insufficiency.
