    Abstract:
    PURPOSE: This study was performed to evaluate the characteristics of the Voice Handicap Index (VHI), a self-assessment measure, for patients with unilateral vocal fold paralysis (UVFP) who underwent arytenoid adduction (AA), in comparison with postoperative vocal function examinations. METHODS: A retrospective chart review was conducted for patients who underwent AA at Tohoku University Hospital during the period between 2014 and 2017. VHI was compared before and after surgery; moreover, correlations were assessed between the VHI and other voice measurements, including perceptual assessment of voice, as well as aerodynamic and acoustic measures. Factors involved in the VHI score were explored by multivariate analysis. RESULTS: Forty-three UVFP patients (28 males, age 32-81 years; 15 females, age 34-80 years) were enrolled in the study; the average age of all patients was 61.5 years (32-81 years). Among the enrolled patients, 33 (76.7%) left and 10 (23.3%) right vocal folds were impaired. After surgery, nearly all of the patients exhibited significantly improved VHI score; each of the three subscales (functional, physical, and emotional) was also improved. The postoperative VHI correlated mildly with several values of the other voice measurements, with the exception of the mean flow rate. Multivariate analysis showed that the sole variable associated with postoperative VHI score was preoperative VHI. CONCLUSIONS: The postoperative VHI likely reflects improvement in the voices of the patients with UVFP. Although there were weak correlations with other voice measures, postoperative VHI is a relatively independent measurement parameter for patients with UVFP who underwent AA.
