Abstract
|
|
|
|
This study investigates the relationship between dysphonia severity index(DSI) and voice handicap index(VHI). Seventeen patients with a vocal nodule and twenty patients with laryngopharyngeal reflux(LPR) patients participated in this study. Results showed that there is no significant difference in either DSI or VHI between vocal nodule and LPR patients, with a weak negative correlation between DSI and VHI. Results also showed that there is significant difference only in both MPT and Fhi of all DSI parameters between vocal nodule and LPR patients. These results suggest that voice evaluation should be conducted both objectively in terms of acoustical and aerodynamic parameters and subjectively in terms of GRBAS and VHI.
