Background and Objectives The purpose of this study was to investigate acoustic (acousticvoice quality index, AVQI) and auditory-perceptual evaluation (grade, rough, breathy, asthenic,strained; GRBAS and consensus auditory-perceptual evaluation of voice; CAPE-V) as apredictor of voice recovery after laryngeal microsurgery (LMS) in patients with vocal polyp. Subjects and Methods A total of 68 patients with vocal polyp participated in this study. Voice samples were analyzed for AVQI by Praat and auditory-perceptual ratings were performedby three speech language pathologists. Voice handicap index-10 (VHI-10) was evaluatedby patients themselves. Results Decreased AVQI, VHI-10, overall severity (OS), and increased smoothed cepstralpeak prominence (CPPS) values were measured and statistically significant changes were notedafter LMS. The ratio of Grade 0 and Grade 1 was increased. AVQI was correlated withCPPS, Grade, and OS, but not with VHI-10. The voice recovery of pedunculated polyp appearedin all vocal polyp sizes after LMS, but statistically significant differences were found only insmall and medium sizes. After LMS of sessile polyps, AVQI, VHI-10, and OS decreased whereasCPPS increased; however, statistically significant difference was confirmed only in VHI-10and OS. The receiver operating characteristic curve analysis showed the following results:AVQI [cutoff=5.5, sensitivity=61.8%, specificity=76.5%, area under the curve (AUC)=0.712],CPPS (cutoff=5.0, sensitivity=89.7%, specificity=48.5%, AUC=0.743), VHI-10 (cutoff=13.0,sensitivity=77.9%, specificity=89.7%, AUC=0.893), Grade (cutoff=2.0, sensitivity=70.6%,specificity=69.1%, AUC=0.728), and OS (cutoff=51.0, sensitivity=86.8%, specificity=66.2%,AUC=0.833). Conclusion Acoustic and auditory-perceptual variables showed significant positive changesand predicted recovery of voice. In this study, we believe that the acoustic and auditory-perceptualevaluations.
