In our study, we aimed to compare the objective and subjective voice analysis re-sults of the patients with CPAP treatment indi-cation after polysomnography performed in the sleep disorders center before the start of CPAP treatment, the 1st month, and the 3rd month after the treatment.PATIENTS AND METHODS: Patients were asked to say the vowels /alpha:/ for 5 seconds, re-spectively for voice recording. MPT and S/Z ra-tios were also recorded. Using the Praat voice analysis program Jitter%, Shimmer%, HNR, f0 values were obtained. VHI-10 questionnaire was applied. The voice analysis results of the patients before and after the treatment were compared.RESULTS: 26 patients were included in the study. Since 8 of these patients did not come to the 3rd month evaluation, the study was complet-ed with the data of 18 patients. In our study, at the end of the 3rd month, no difference was found in terms of the fundamental frequency, Shimmer%, HNR, and S/Z values. There was a statistically significant decrease in Jitter% at the 1st month after treatment and 3rd month after treatment compared to pre-treatment (p=0.05, p=0.018). There was a statistically significant decrease in MPT at the 1st month after treatment and 3rd month after treatment compared to pre-treatment (p<0.001, p<0.001). There was a statistically sig-nificant decrease in VHI-10 at the 1st month and 3rd month after treatment compared to pre-treat-ment. Furthermore, there was statistically signifi-cant difference between 3rd month after treatment compared to 1st month after treatment. (p=0.043, p=0.030, p=0.029).CONCLUSIONS: Our study showed that CPAP treatment had both objective and subjective pos-itive effects on voice recovery in the OSA patient group.eninfo:eu-repo/semantics/closedAccessAcousticCPAPVHI-10PhonationPolysomnographyObstructive sleep apneaArticle26196972697836263577WOS:000877188200013Q2
