ABSTRACT
BACKGROUND AND OBJECTIVES:There are several methods to improve voice quality in the patients with paralyzed vocal cord, such as thyroplasty type I, injection, arytenoid adduction. The goal of surgical medialization of the paralyzed vocal fold is to attain complete glottic closure. The purpose of this study is to evaluate the effectiveness of thyroplasty type I through qualifying the vocal function and glottal gap. MATERIALS & METHODS: We experienced 20 cases of unilateral vocal fold paralysis who underwent thyroplasty type I. We performed preoperative and postoperative videoimage analysis (normalized glottal gap area) and computer-assisted voice analysis in all patients. RESULTS: The glottal gap was significantly reduced after thyroplasty type I. Postoperative voice quality was characterized by an improved pitch and amplitude perturbation (jitter and shimmer), maximum phonation time and subglottic pressure . But noise to harmonic ratio was not improved. CONCLUSION: Thyroplasty type I is an effective method in the point of regaining glottal closure and vocal function.
