Sixty patients diagnosed with obstructive sleep apnea syndrome (OSAS) underwent uvulopalatopharyngoplasty (UPPP). The effects of surgery were studied based on endoscopic findings during drug-induced sleep and determination of the apnea-hypopnea index (AHI) before and after the operation. Changes in the form of the airway during sleep in the recumbent position were observed, and the role of upper airway endoscopy in the diagnosis and surgical treatment of OSAS was determined. The site of airway… CONTINUE READING
