摘要
Objective: To investigate changes in S3 sleep and the apnea hypopnea index (AHI), SpO(2) desaturation and CT90, and to determine changes in the degree of airway collapse and in the cross-sectional area of the retropalatal and lingual region in obstructive sleep apnea hypopnea syndrome patients. Method: All subjects underwent overnight polysomnography and were evaluated using Muller's test and magnetic resonance imaging at baseline, 3, and 12 months following surgery. Result: The mean S3 scores in patients receiving uvulopalatopharyngoplasty combined with genioglossus advancement (UPPP-GA) or UPPP combined with tongue base advancement using the Repose (TM) system (UPPP-TBA) noticeably increased. Marked improvement was seen in the mean AHI, LSO2, and CT90 scores 3 and 12 months following surgery compared to baseline. Airway collapsed by 25-50% in the greatest proportion undergoing surgery at the tongue base. Conclusion: UPPP-GA and UPPP-TBA more effectively improve S3 sleep, and mean AHI, LSO2, and CT90 scores. In addition, they effectively alleviate airway obstruction by improving the cross-sectional area of these regions. (C) 2014 S. Karger AG, Basel
