Description
Summary:The purpose of this study was to the usefulness of a five-variable model predicting perceived voice severity and incorporating acoustic analysis based on cepstral analysis and self-reported questionnaires, for measuring voice recovery after endolaryngeal phonomicrosurgery in patients with vocal fold polyps. In this study, 72 patients with vocal fold polyps were included. Two voice evaluations, including acoustic analysis, self-reported questionnaires, and auditory perceptual assessments for each patient, were implemented before and after endolaryngeal phonomicrosurgery. Using these evaluations, we compared the mean values of the perceptual evaluation of voice, acoustic analysis parameters, self-reported questionnaires, and the five-variable model estimated severity pre- and post-endolaryngeal phonomicrosurgery. Various parameters related to acoustic analysis, self-reported questionnaires, and auditory perceptual assessments were useful for measuring voice recovery after endolaryngeal phonomicrosurgery. In particular, a five-variable model incorporating spectral/cepstral analyses and self-reported questionnaires was able to effectively track voice changes after endolaryngeal phonomicrosurgery. We verified that most of the variables and the five-variable model were useful for measuring voice recovery in patients with vocal polyps after endolaryngeal phonomicrosurgery.
