When we operate on a vocal polyp or a vocal nodule with laryngeal microscopy, we always carefully measure their length and width then multiply the length by the width to get the area. We examined whether there is a correlation between the area of these lesions and the acoustic analysis of voice. Before the surgery and one month post-operation, we checked five acoustic parameters, maximum phonation time (MPT), range of voice, mean air flow rate (MFR) and acoustic analyses (jitter% and shimmer%). By doing this, we could arrive at the improvement rate of each of the five acoustic parameters. We examined whether there was a correlation between the lesion area and acoustic parameters before surgery and the improvement rates of these acoustic parameters. Examinations of polyps showed a correlation between the size and range of voice and Jitter% pre-operation, and showed a correlation between the size and improvement rate of range of voice, MFR, Jitter% and Shimmer post-operation. On the other hand, examination of nodules showed a correlation only between the size and range of voice pre-operation. Next we examined the correlation between the size and these acoustic parameters in the Elite vocal performer (EVP) group and extra EVP group. In the examinations of polyps, the EVP group showed a lower correlation between the size and acoustic parameters than in the extra EVP group. On the other hand, in the examinations of nodules, correlation between the size and acoustic parameters was low in both the EVP and extra EVP group.
