December 2011. Epworth Sleepiness Scale ESS score, snoring, the feeling of having slept well and polysomnography were used for the evaluation of surgical outcomes. In addition, we determined whether baseline polysomnography, cephalometry, and authropometry data could predict GA and UPPP success or failure. Results : The mean ESS score decreased significantly from 12.96 to 7.08. The mean apnea hypopnea index AHI improved from 37.3 to 19.33. Objective success as evaluated by a 50% reduction in AHI or by AHI 15 was obtained in 16 of 24 patients. The lowest oxygen saturation and stage 1 and stage 2 were also improved significantly. There were no major postoperative complications. There were significant differences in SNA, SNB, FX and PNS P between the success and failure of GA and UPPP. The indication of GA and UPPP were SNA 79.11 degrees, SNB 75.69 degrees, FX 78.67 degrees, and 36.79 mm PNS P 42.29 mm. Conclusion : GA and UPPP surgeries are effective and safe for patients with moderate and severe OSAS. However, further studies are necessary to decide definitively if GA and UPPP are appropriate treatments for OSAS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
