This study compares glottal closure and voice quality after use of 2 different medialization implant types: VoCoM and TVFMI.</jats:p></jats:sec><jats:sec><jats:title>Methods.</jats:title><jats:p>In all, 26 patients with unilateral vocal fold paralysis following thoracic surgery underwent medialization thyroplasty. In 11 patients (group I), a hydroxyapatite implant (VoCoM) was used. In 15 patients (group II), a titanium implant (TVFMI) was used. Preoperative and postoperative glottal closure and voice function were assessed with videostroboscopy, perceptual and objective voice measures, and the Voice Dysfunction Index (VDI).</jats:p></jats:sec><jats:sec><jats:title>Results.</jats:title><jats:p>Group II showed a higher rate of complete glottal closure and greater improvement in perceived hoarseness, maximal phonation time, and maximal voice intensity than those in group I.</jats:p></jats:sec><jats:sec><jats:title>Conclusions.</jats:title><jats:p>With the individually adjustable titanium implant, better glottal closure and better functional outcome (phonation time and voice quality) were achieved. © 2010 Wiley Periodicals, Inc.
