People with obstructive sleep apnea (OSA) have disrupted sleep and low blood oxygen levels. When obstructive sleep apnea occurs, the tongue or soft palate obstructs against the back of the throat. This blocks the upper airway and airflow stops. When the oxygen level in the brain becomes low enough, the sleeper partially awakens, the obstruction in the throat clears, and the flow of air starts again, usually with a loud gasp.
Repeated cycles of decreased oxygenation lead to very serious cardiovascular problems. Additionally, these individuals suffer from excessive daytime sleepiness, depression, and loss of concentration.
Some patients have obstructions that are less severe called Upper Airway Resistance Syndrome (UARS). In either case, the individuals suffer many of the same symptoms.
Sleep Apnea Treatment
The first step in treatment for sleep apnea resides in recognition of the symptoms and seeking appropriate consultation. Oral and maxillofacial surgeons offer consultation and treatment options.
In addition to a detailed history, the doctors will assess the anatomic relationships in the maxillofacial region with x-ray analysis to help determine the area where an obstruction may be present. To confirm the amount of cardiovascular compromise and decreased oxygenation levels, a sleep study may be recommended to monitor an individual overnight.
Treatment Options for Sleep Apnea
There are several treatment options available. An initial treatment may consist of using a nasal CPAP machine that delivers pressurized oxygen through a nasal mask to limit obstruction at night. Lower jaw repositioning appliances can also be used in some cases to help limit the obstruction.
In more severe cases, the bones of the upper and lower jaw may be repositioned to increase the size of the airway (orthognathic surgery). This procedure is done in the hospital under general anesthesia and requires a one to two day overnight stay in the hospital. For selected patients this type of surgery has been shown to have success rates of at least 85-90% in curing obstructive sleep apnea.
OSA is a very serious condition that needs careful attention and treatment. Most major medical plans offer coverage for diagnosis and treatment.
