Summary
Objectives
We aimed to examine the effects of anterior palatoplasty (AP) and functional expansion
sphincter pharyngoplasty (FESP) on voice quality in patients with OSAS and to compare
them with each other.
Merhods
The study included 380 patients who came to the Otorhinolaryngology Clinic of our
hospital with symptoms of snoring and sleep apnea between April 2020 and April 2022
and were referred to the sleep laboratory for polysomnography (PSG).Forty patients
who met the study criteria and underwent AP and 26 patients who underwent FESP were
included in the study. All surgeries were performed under general anesthesia by the
same otolaryngologist within 1 month at the latest after sleep endoscopy. Acoustic
voice analysis was performed using the Praat voice analysis program preoperatively
and postoperatively at 6 months. F0, jitter, shimmer, and NHR (noise-to-harmonic ratio)
were compared between the groups pre and postoperatively.
Results
There were 20 females and 20 males in the AP group, 12 females and 14 males in the
FESP group, There was no statistically significant difference in sex distribution
between the groups (P = 0.952). The difference between the preop and postop F0, jitter, shimmer, and NHR
in both the AP and FESP groups was statistically significant (P < 0.01). After AP and FESP surgeries, F0 values increased, jitter, shimmer and
NHR values decreased (P < 0.01).F0, jitter, shimmer, and NHR changes were the greatest in the FESP group.(P < 0.01).
Conclusion
Positive changes in F0, jitter, shimmer, and NHR were greatest in the FESP group significantly.
FESP surgery affects voice quality more than AP surgery in patients with OSAS.
