[Application of voice acoustic analysis in microlaryngoscopic surgery]
Objective:
To evaluate the relationship between the effect of microlaryngoscopic surgery of vocal polyp and the change of all-parameters.
Method:
Acoustic parameters of 80 patients with vocal polyp were measured by Dr. Speech Sciente for Windows, and analyzed preoperatively and postoperatively.
Result:
The jitter, shimmer and NNE were different significantly between preoperative and postoperative, the NNE and shimmer were more sensitive than jitter.
Conclusion:
The NNE and shimmer of acoustic parameter are objective parameter to evaluate the effect of the microlaryngoscopic surgery of vocal polyp.
