Objective. To assess the clinical parameters for successful uvulopalatopharyngoplasty in the management of obstructive sleep apnoea syndrome documented with pre- and postoperative polysomnography.Materials andMethods. A study group of 50 patients diagnosed as having OSA by full night polysomnography were assessed clinically and staged on basis of Friedman staging system. BMI and neck circumference were considered, and videoendoscopy with Muller’s maneuver was done in all to document the site of obstruction. The study group divided into surgical and nonsurgical ones. Twenty-two patients out of fifty were then selected for uvulopalatopharyngoplasty. The selection of surgical group was done primarily on basis of clinical parameters like neck circumference, Friedman stage of the patient and site, and/or level of obstruction of patient. Postoperative polysomnography was done six months after surgery to document the change in AHI score. Result. The study group consists of fifty patients with mean age of 44.4 ± 9.3 years. UPPP was done in twenty-two, and the result of the surgery as defined by 50 % reduction in preoperative AHI with postoperative AHI < 20/h was seen to be 95.2%. Postoperative change in AHI done after 6-month interval was seen to be statistically significant with P value < 0.001. Conclusion. UPPP is ideal option for management of obstructive sleep apnoea syndrome in properly selected patients on the basis of Friedman stage and site of obstruction detected by videoendoscopy with Muller’s maneuver. 1
