INTRODUCTION: This study aims to analyze the differences in voice acoustic analysis according to the localization of polyps in the vocal fold.
METHODS: Between January 2017 and June 2018, a total of 52 patients (38 males, 14 females; mean age 40.5 years; range, 23 to 61 years) with a vocal polyp were retrospectively analyzed. The length of the vocal fold was measured and the location of lesions were classified as anterior, anterior-middle, and middle. Fundamental frequency (F0mean, F0min, F0max), jitter, shimmer, noise harmonic ratio (NHR), and maximum phonation time (MPT) were also recorded.
RESULTS: Vocal polyps were localized in the anterior in 12, in the anterior-middle in 16, and in the middle in 24 patients. In the intra-group analyses, MPT, F0min, and NHR were found to be statistically significant. According to the overall average, MPT in the anterior group, shimmer and NHR in the anterior-middle group, and F0mean and F0min values in the middle group were found to be significant.
DISCUSSION AND CONCLUSION: In vocal polyps, MPT was shorter in anterior lesions, the F0 mean value was high in middle lesions, and voice quality was more affected in the anterior-middle lesions, as the vocal fold vibration stability was disrupted and the noise parameter was high.

Keywords: Acoustic analysis, voice, vocal polyp, vocal fold.
