Multilevel Obstructive Sleep Apnea Surgery.

Abstract

Continuous positive airway pressure (CPAP) is the primary treatment of obstructive sleep apnea/hypopnea syndrome (OSA). Most sleep physicians are in agreement that a certain number of OSA patients cannot or will not use CPAP. Although other conservative therapies, such as oral appliance, sleep hygiene, and sleep positioning, may help some of these patients, there are many who fail all conservative treatments. As sleep surgeons, we have the responsibility to screen patients for both symptoms and signs of OSA. As experts of upper airway diseases, we often view an airway clearly and help the patient understand the importance of assessment and treatment for OSA. Surgery for OSA is not a substitute for CPAP but is a salvage treatment for those who failed CPAP and other conservative therapies and therefore have no other options. Most early studies and reviews focused on the efficacy of uvulopalatopharyngoplasty, a single-level procedure for the treatment of OSA. Since OSA is usually caused by multilevel obstructions, the true focus on efficacy should be on multilevel surgical intervention. The purpose here is to provide an updated overview of multilevel surgery for OSA patients.
