Abstract:
BACKGROUND AND OBJECTIVES: The purpose of this study was to investigate acoustic (acoustic voice quality index, AVQI) and auditory-perceptual evaluation (grade, rough, breathy, asthenic, strained; GRBAS and consensus auditory-perceptual evaluation of voice; CAPE-V) as a predictor 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 performed by three speech language pathologists. Voice handicap index-10 (VHI-10) was evaluated by patients themselves. RESULTS: Decreased AVQI, VHI-10, overall severity (OS), and increased smoothed cepstral peak prominence (CPPS) values were measured and statistically significant changes were noted after LMS. The ratio of Grade 0 and Grade 1 was increased. AVQI was correlated with CPPS, Grade, and OS, but not with VHI-10. The voice recovery of pedunculated polyp appeared in all vocal polyp sizes after LMS, but statistically significant differences were found only in small and medium sizes. After LMS of sessile polyps, AVQI, VHI-10, and OS decreased whereas CPPS increased; however, statistically significant difference was confirmed only in VHI-10 and 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 changes and predicted recovery of voice. In this study, we believe that the acoustic and auditory-perceptual evaluations.
