Effects of Adenotonsillectomy on Acoustic, Perceptual, and Aerodynamic Parameters of Voice
Journal Title: Dicle Tıp Dergisi - Year 2016, Vol 43, Issue 2
Abstract
Objective: In this study, we aimed to investigate the acoustic, perceptual and aerodynamic changes of voice after adenotonsillectomy by using objective methods. Methods: Thirty children, who underwent adenotonsillectomy surgery were included. Voice samples were recorded 1 day before and 1 month after the surgery. LingWAVES programme was used as voice analysis program. Mean, maximum and minimum fundamental frequency, Jitter, Shimmer, Glottal to Noise Excitation ratio, Irregularity, Noise, Overall Severity, S time, Z time, S/Z ratio, and Maximum Phonation Time parameters were recorded and compared. Results: Shimmer, irregularity, Overall Severity, S/Z Time parameters were significantly lower (p=0.001) and Maximum Phonation Time significantly higher (p=0.001) in the postoperative period than preoperative period. In contrast, no significant differences were observed in the mean fundamental frequency, maximum fundamental frequency, minimum fundamental frequency, jitter, Glottal to Noise Excitation, S time and Z time (p>0.05). Conclusion: The changes in some acoustic, aerodynamic and perceptual parameters were monitored after adenotonsillectomy. Therefore, the families of children who underwent adeotonsillectomy should be warned for any possible changes in voice colors after surgery. Key words: Adenotonsillectomy, acoustic analysis, perceptual analysis, aerodynamic analysis
