Quiz Ref ID Adult obstructive sleep apnea (OSA) is associated with numerous adverse effects if left untreated, including daytime sleepiness, reduced quality of life, increased cardiovascular morbidity and mortality, and an increased risk of motor vehicle crashes.
1-3 Quiz Ref ID A narrow or unstable upper airway
4 predisposes to episodes of complete or partial airflow reduction (ie, obstructive apnea or hypopnea) during sleep when pharyngeal dilator muscle tone falls. Continuous positive airway pressure (CPAP) delivered by mask, or jaw advancement with an oral appliance, can alleviate obstruction; however, many patients either refuse these therapies, use them inconsistently, or (as in the case of oral appliances) achieve suboptimal efficacy, leaving at least 50% of patients without effective treatment
5,6 and exposed to the risk of serious long-term morbidity. Surgical treatments aim to enlarge and stabilize the upper airway and may provide an option for patients in whom conventional medical treatment had failed.
7 However, to date, there have been few randomized trials evaluating the benefits and complications of these surgical procedures compared with controls,
8-11 and most have tested surgical treatment at a single level of the upper airway in highly select patients.
