Treatment Outcomes of Arytenoid Dislocation by Closed Reduction: A Multidimensional Evaluation

Abstract

Objective: This study aimed to investigate the treatment outcomes of arytenoid dislocation by a multidimensional evaluation.

Methods: From April 2010 to May 2018, the records of 57 patients with a history of arytenoid dislocation were reviewed. All the patients were treated with closed reduction under local anesthesia. Arytenoid motion, grade, roughness, breathiness, asthenia, strain, maximum phonation time, self-assessed Voice Handicap Index, and acoustic voice analysis were used to evaluate the clinical outcomes.

Results: Following closed reduction, 57 patients were divided into "recovered" (n = 24), "improved" (n = 15), and "ineffective" (n = 18) groups. There were no major complications resulting from surgical intervention.

Conclusion: Closed reduction under local anesthesia continues to be an effective and well-tolerated method for treating arytenoid dislocation. The trichotomy of the treatment results of arytenoid dislocation by a multidimensional evaluation may be more accurate to evaluate the results of arytenoid dislocation.
