Abstract

Background: The aim of this study was to assess the application of Voice Handicap Index (VHI) in the diagnosis of occupational voice disorders in female teachers. Material and Methods: The subjective assessment of voice by VHI was performed in fifty subjects with dysphonia diagnosed in laryngovideostroboscopic examination. The control group comprised 30 women whose jobs did not involve vocal effort. Results: The results of the total VHI score and each of its subscales: functional, emotional and physical was significantly worse in the study group than in controls (p < 0.001). The analysis of VHI-score distribution showed that 68% of female teachers estimated their own voice problems as a moderate disability, while 12% of them reported severe voice disability. However, all non-teachers assessed their voice problems as slight, their results ranged at the lowest level of VHI score. Conclusions: This study confirmed that VHI as a tool for self-assessment of voice can be a significant contribution to the diagnosis of occupational dysphonia. Med Pr 2007;58(5):393ś402
