Background and Objectives The aim of this study was to compare between preoperative and postoperative voices by subjective auditory perceptual evaluation and objective acoustic analysis. The study also analyzed the acoustic parameters that best reflected the auditory perceptual characteristics in laryngeal microsurgery. Subjects and Method The records of 49 patients who had been diagnosed as benign vocal fold mucosal diseases and had undergone laryngeal microsurgery were retrospectively analyzed. Preoperative and postoperative voices were assessed by auditory perceptual evaluation using the GRBAS Scale and acoustic analysis using Multi-Dimensional Voice Program (MDVP) and Analysis of Dysphonia in Speech and Voice (ADSV). Correlation between auditory perceptual characteristics and acoustic parameters was analyzed. Results Auditory perceptual evaluation showed that the patients’ voices were improved after the operation. Several acoustic parameters of MDVP related to short-term and long-term variability showed significant improvement. Also, there were significant differences in several cepstral/spectral parameters of ADSV after operation. In the correlation analysis, the overall grade (G) of the GRBAS Scale showed highest correlation with the cepstral spectral index of dysphonia (CSID) (r=-0.700). The roughness (R) of GRBAS Scale was correlated with the smoothed amplitude perturbation quotient of long-term variability of MDVP (r=0.468), breathiness (B) with cepstral peak prominence (r=-0.703) and strain (S) with CSID (r=0.650) (p＜0.01). Conclusion Our results showed that the acoustic parameters were related to the long-term variability of MDVP, and the parameters of cepstrum/spectrum were useful for the objective assessment of voice quality in patients who received laryngeal microsurgery. These parameters were also useful for the quantification of voice quality and abnormality of phonation. Korean J Otorhinolaryngol-Head Neck Surg 2016;59(11):775-9
