Sleep x 9: an approach to treatment of obstructive sleep apnoea/hypopnoea syndrome including upper airway surgery.

This article provides an overview of the management of the obstructive sleep apnoea/hypopnoea syndrome (OSAHS). Where possible, recommendations are based on a review of the relevant literature. With the exception of nasal continuous positive airway pressure, which is considered in greater detail elsewhere in the series, and certain oral appliances, the efficacy of many proposed treatments for OSAHS is not supported by data from randomised controlled clinical trials. To a considerable extent, treatment recommendations are based on data from uncontrolled studies, case series, consensus guidelines, practice parameters, and other less rigorous forms of evidence.
