Objective:Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent episodes of upper respiratory- tract obstruction during sleep and decrease in arterial oxygen saturation. Expansion sphincter pharyngoplasty (ESP) is a simple, safe, and effective method for the surgical treatment of OSAS. The aim of our study was to evaluate the efficacy of ESP with polysomnography (PSG) in OSAS patients.Methods:This study was conducted on patients referred to our center for the treatment of snoring, apnea, witnessed apnea, and daytime sleepiness during 2010- 2018. Overall, 67 patients (16 females, 51 males) who had PSG test at postoperative three months and were considered suitable with history, physical examination, and surgery after PSG were included in the study. Patients were classified into three groups according to OSAS severity: mild, moderate, and severe. Patient age, sex, body mass index (BMI), pre- and postoperative period apnea-hypopnea index (AHI), Epworth sleepiness scores, and PSG data were recorded.Results:The mean BMI of all groups was 27.44±2.73. The postoperative AHI decreased from 18.26±2.23 to 8.01±0.97 (p |
