Background and Objectives: Vocal polyp is the most common disease that causes hoarseness and its incidence is increased currently. The purposes of this study are to investigate the correlation between severity of vocal polyp and acoustic parameters and compare these data with those of the normal Korean.
Materials and Methods: We analyzed the acoustic parameters of sustained vowel for 70 vocal polyp patients and 20 normal controls. A CSL(computerized speech lab) was used to carry out the analysis of the voice sample and statistical analysis was used Spearman correlation coefficient & t-test.
Results: According to the conclusion of correlation analysis, 21 parameters of all the 34 parameters are significant.
Conclusion: These data will be served as basic data for the evaluation of postoperative assessment of the patients with vocal polyp.
