摘要Objectives.To investigate the differences and correlation between the Voice Handicap Index-10 (VHI-10) and the Voice-Related Quality of Life (V-RQOL) in teachers in China with and without voice disorders.Study Design.This is a cross-sectional descriptive analytical study.Methods.The participants were 864 teachers (569 women,295 men) whose vocal cords were examined using a flex-ible nasofibrolaryngoscope.Questionnaire results were obtained for both the VHI-10 and the V-RQOL.Results.Of the 864 participants,409 teachers had no voice disorders and 455 teachers had voice disorders.The most common voice complaint was hoarseness (n =298) and the most common throat complaint was globus pharyngis (n =79) in teachers with voice disorders.Chronic laryngitis (n =218) and polyps and nodules (n =182) were the most fre-quent diagnoses in teachers with voice disorders.Significant differences were seen on the VHI-10 between teachers with and those without voice disorders (P < 0.05) and in function between female and male teachers with voice dis-orders (P < 0.05) and between those with different voice disorders (P < 0.05).Moderate to strong correlations were observed between VHI-10 total score and those for the three domains of the VHI-10 and the V-RQOL (P < 0.0001).Conclusions.There is a high prevalence of voice disorders in teachers.Teachers with voice disorders have poor voice-related quality of life,with more impairment seen among female than male teachers.Different groups of voice disorders have different effects on voice-related quality of life.A moderate correlation was found between the results of the VHI-10 and the V-RQOL.
