Long-term efficacy of expansion sphincter pharyngoplasty in obstructive sleep apnea syndrome

Abstract

Purpose

The aim of this study was to analyze both short-term and long-term results of the expansion sphincter pharyngoplasty surgery, which is commonly used in obstructive sleep apnea syndrome (OSAS) and to compare it with objective and subjective methods.

Methods

Patients who underwent expansion sphincter pharyngoplasty were included in the study. Polysomnography at postoperative sixth-month, Epworth Sleepiness Scale, and visual analog score of snoring (VAS) were used to assess short-term results. Epworth Sleepiness Scale (ESS) and visual analog score of snoring (VAS) at postoperative third-year were used for long-term results. Sixth-month and third-year data before and after the surgery were compared. Possible complications and morbidity rates related to surgery were evaluated.

Results

Of 39 patients, OSAS was assessed as mild in 16 (41%), moderate in 14 (36%), and severe in 9 (23%). Mean age of patients was 43.2 ± 7.5, and 21 were men (54%). According to postoperative six-month PSG data, the apnea hypopnea index (AHI) values decreased significantly from 25.2 ± 8.3 to 11.6 ± 6.9/h, p=0.012. There were decreases in ESS from baseline to 6-month and 3-years from 10.4, to 4.4, and 4.4, and VAS scores changed from 8.6 to 1.6 and 1.9, p<0.05. No serious complications were observed in patients in the early and late postoperative period.

Conclusion

The expansion sphincter pharyngoplasty procedure is an important option for OSAS surgery with long-term effective results and low morbidity and complication rates.
