What is obstructive sleep apnea?
Obstructive sleep apnea (OSA) is a breathing disorder characterized by brief interruptions of breathing during sleep due to a blockage in the airway. The most common causes of airway blockage include throat muscles, tongue, tonsils, or soft palate falling back into the throat.
OSA is typically diagnosed using a polysomnogram or "sleep study." During a sleep study, a sleep technician monitors brain activity and body system functioning while a patient rests overnight at a sleep clinic or at home. The sleep physician evaluates the data collected during the sleep study to diagnose sleep disorders and recommend treatment. Dr. McManis works together with sleep physicians to treat obstructive sleep apnea with oral appliance therapy.
