Abstract
|
|
|
Background and objective: In benign laryngeal diseases, voice quality is major concern to both patients and clinicians. The purpose of this study is to identify the acustic parameters that can represent preoperative pathologic and
postoperative
improved voice and to investigate quantitative changes of them. Using these data, We intend to disclose the mechanisms of voice change and apply to programs that can predict postoperative voice using preoperative voice data.
Material and Methods: We examined 47 patients who experienced laryngeal microsurgery due to pathologic voice with benign laryngeal diseases and 50 normal controls. The voice was analysed by Multi-Dimensional Voice Program in Computerized
Speech
Lab 4300 B.
Results: All preoperative parameter's values except NHR and VTI were higher than control group. Among them, the values of frequency and amplitude perturbation related parameters increased most highly. Most parameter's values after
operation
showed statistically no significant difference from those of control group. Postoperative parameter's values reduced above 50% of PPQ, RAP, sPPQ, Jitt, and Shim than preoperative state.
Conclusion: The results showed that Jitter and Shimmer represented well the pathologic voice of benign laryngeal disease and very closely related between improvements of both these parameters and voice quality after operation. We also
considered
that these data will be available in the program of postoperative predictive voice synthesis using preoperative voice data.
