Clinical Efficacy of Arytenoid Adduction in Unilateral Vocal Cord Paralysis

Arytenoid adduction is used in treating unilateral vocal cord paralysis. In 7 subjects with breathy hoarseness due to such paralysis undergoing arytenoid adduction from 2006 to 2008, preoperative mean maximum phonation time (MPT) of 4.6 ± 1.3 increased to 13.4 ± 1.7 postoperatively. Hoarseness was ameliorated in all subjects. These results indicate that arytenoid adduction is effective in treating unilateral laryngeal paralysis.
