Several instruments have been designed specifically to evaluate quality of life outcomes in dysphonic populations. The best validated and most utilized surveys are the Voice Handicap Index (VHI) , the Voice Outcome Survey (VOS) and the Voice-Related Quality of Life (V-RQoL) . These instruments were designed to be used in the assessment of dysphonic patients and were validated in adult populations. Since their dissemination, each of these instruments have produced a pediatric analogue, namely a pediatric VOS (PVOS) , a pediatric V-RQoL and a pediatric VHI (PVHI).
