An abnormal nasal airway is one of the major contributors to poor sleep, and also one of the major predictors of failure of devices such as CPAP, mandibular advancement devices and Provent/Theravent™. Improving the nasal airway with medical or surgical interventions improves sleep. When needed, sometimes nasal surgery is the only intervention that will improve CPAP tolerance. Minor improvements have marked effects.

No single structural abnormality explains nasal problems in sleep disorders. A careful expert evaluation of the nasal valve, nasal septum, turbinates, sinuses and tissues of the back of the nose is important for many individuals with sleep disorders to look for correctable medical causes or to identify structural abnormalities. 

If surgery is required, it is most often done under local anesthesia with a rapid return to work or other normal activity.
