Evaluation of multiple surgeries as therapeutic options for Obstructive Sleep Apnea Syndrome

Obstructive Sleep Apnea Syndrome (OSAS) is a chronic disease characterized by repeated airfl owobstruction in the upper airway. Location of obstructive site is essential for proper surgical planning.Objective: To evaluate the success rate of multiple surgeries, in various combinations, in thetreatment of Moderate and Severe OSAS.Methods: Fifty patients with moderate and severe OSAS subjected to multiple surgeries for treatmentwere studied, and the laboratory values of pre -and postoperative polysomnography were analyzed.Results: Considering the reduce AHI from an average of 47.9 events / hour (± 23.30) preoperatively toa mean postoperative value of 19.82 events / hour (± 21.16) in cases of moderate OSAS, AHI was reducedfrom 22.89 to 18.50 events / hour. In severe cases of OSAS, the AHI reduced from 58.62 to 20.38 events/ hour.Conclusion: Several combinations of multiple surgeries for OSAS are valid for the treatment -resistantpatients using CPAP alternatives. The success rate is signifi cantly better in severe cases than in mildones. Among the surgeries, craniofacial surgery contributed to improve postoperative AHI and showed agreater reduction than in patients not undergoing this technique.
