[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.


METHODS
Acoustic parameters of 80 patients with vocal polyp were measured by Dr. Speech Sciente for Windows, and analyzed preoperatively and postoperatively.


RESULTS
The jitter, shimmer and NNE were different significantly between preoperative and postoperative, the NNE and shimmer were more sensitive than jitter.


CONCLUSIONS
The NNE and shimmer of acoustic parameter are objective parameter to evaluate the effect of the microlaryngoscopic surgery of vocal polyp.
