Abstract
Objective Whereas uvulopalatopharyngoplasty (UPPP) was the standard surgical procedure for obstructive sleep apnea prior to 2007, multilevel surgery has become the standard since that time. This study compares morbidity and mortality rates of the stand-alone UPPP with those of multilevel sleep surgery that includes UPPP. Methods Patients undergoing UPPP between 2007 and 2014 were identified in the American College of Surgeons National Surgical Quality Improvement Program database. UPPP was defined by Current Procedural Terminology codes 42145 and 42950. Primary outcomes were incidence of morbidity and mortality. Rates were compared between a control group with UPPP only and a group with multilevel surgery. Results A total of 2674 cases were analyzed. The incidence of complications in the UPPP-only group was 1.6% (0.09% fatal); in the multilevel surgery group, 4.63% (0.19% fatal). The difference in overall and nonfatal complications is statistically significant ( P < .01); however, values for fatal complications are too low for comparison. There is a statistically significant ( P < .01) positive correlation ( R(2) = 0.92) between year of operation and rate of complications, with increased incidence of complications in more recent years. Discussion Complication rates for multilevel sleep surgery are higher than those of stand-alone UPPP, and overall complication rates have been increasing in recent years. As UPPP supplemented with multilevel surgery is now the standard surgical treatment for most cases of obstructive sleep apnea-hypopnea syndrome, historical complication rates based predominantly on patients undergoing UPPP only underestimate complication rates of modern sleep surgery. Implications for Practice It is reasonable to inform patients that multilevel procedures bring an increased risk of complications, and patient selection should be guided accordingly.
