Do I have Sleep Apnea?
People with obstructive sleep apnea (OSA) have disrupted sleep and low blood oxygen levels. When obstructive sleep apnea occurs, the tongue is sucked 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.
Sleep Apnea Symptoms
Repeated cycles of decreased oxygenation lead to very serious cardiovascular problems. Additionally, these individuals suffer from
- excessive daytime sleepiness
- loss of concentration
- Hypertension and other cardiac abnormalities

Sleep Apnea Diagnosis
The first step in treatment 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 cephalometic (skull x-ray) analysis, the doctors can ascertain the level of obstruction. Sometimes a naso-pharyngeal exam is done with a flexible fiber-optic camera. To confirm the amount of cardiovascular compromise and decreased oxygenation levels, a sleep study is recommended to monitor an individual overnight.
Sleep Apnea Treatment
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. Weight loss from diet modification and exercise has been found to be beneficial.
Oral appliances that move and maintain the lower jaw in an anterior position have been found to be effective in keeping the airway open.
To determine the effectiveness of treatment a repeat sleep study is recommended.
