The Isshiki thyroplasty operations (types I through IV, arytenoid adduction) and the arytenoid fixation for arytenoid dislocation or subluxation are ostensibly revisable and reversible if postoperative vocal results are not satisfactory. However, objective data and results after thyroplasty revision are lacking. This retrospective analysis is meant to address the issues of revisibility and reversibility of all thyroplasty operations. Forty-six of 326 thyroplasty patients have undergone a total of 56 revisions of a previous thyroplasty operation. All types of thyroplasty operations have been revised and/or reversed, including the arytenoid adduction and arytenoid fixation techniques. Objective data including jitter, shimmer, and harmonics-to-noise ratio from prerevision and postrevision video-stroboscopic recordings show improvement in the voice in the majority of patients. The Isshiki thyroplasty operations and the arytenoid fixation are both reversible and revisable, with good results after revision.
