ABSTRACT
Background and Objectives : Vocal polyps and nodules are representative chronic benign laryngeal disease. Treatment options for vocal polyp and nodule in general include voice therapy or laryngeal microsurgery. The purpose of this study was to analyze voice results before and after laryngeal microsurgery.
Materials and Method:
Vocal polyp and vocal nodule patients were treated by laryngeal microsurgery from March 2004 to December 2006 at Kosin University Hospital. All were women. Voice analysis studies were done before and after laryngeal microsurgery. Five measurements were performed: MPT, Fo, jitter, shimmer and NHR.
Results:
There was significant improvement in the vocal polyp patients regarding MPT, jitter, shimmer and NHR. Also there was significant improvement in the vocal nodule patients regarding MPT, jitter and shimmer.
Conclusion:
MPT, jitter, shimmer and NHR will be effective acoustic parameters in documenting the quantitative changes in the vocal polyp patients. MPT, jitter and shimmer will be effective acoustic parameters in documenting the quantitative changes in the vocal nodule patients before and after laryngeal microsurgery.
