The Montgomery thyroplasty implant was designed to specifically medialize the vocal process of the arytenoid. In over 300 procedures done by the senior author, reliable closure of the posterior commissure was achieved in the vast majority of cases. No patients in this series have gone on to require arytenoid adduction procedures. Experience has shown that it is necessary to carefully dissect the perichondrium from the cartilage lateral to the vocal process of the arytenoid to allow proper implant positioning. These results have been confirmed by postoperative clinical and radiographic evaluations, as well as cadaveric dissection. The results of this analysis are presented.
