What is Sleep Apenea?
Sleep apnea is a disorder characterized by a reduction or pause of breathing (airflow) during sleep. It is common among adults but rare among children. The treatment of sleep apnea may be either surgical or nonsurgical. 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.
What are obstructive sleep apnea symptoms?
Obstructive sleep apnea has many well-studied consequences. First, as you would expect, it disrupts sleep. Patients with disrupted sleep cannot concentrate, think, or remember as well during the day. This has been shown to cause more accidents in the work place and while driving. Daytime sleepiness, fatigue, frequent naps, headaches, irritability, insomnia, and poor memory and attention are some of the other common symptoms associated with sleep apnea as a result of insufficient sleep.
What are some of the complications of sleep apnea?
Obstructive sleep apnea (OSA) may be a risk factor for the development of other medical conditions. High blood pressure (hypertension), heart failure, heart rhythm disturbances, atherosclerotic heart disease and pulmonary hypertension are the complications of untreated obstructive sleep apnea.
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 may be recommended to monitor an
individual overnight.
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.
One of the surgical options is an uvulo-palato-pharyngo-plasty (UPPP), which is
performed in the back of the soft palate and throat. A similar procedure is sometimes
done with the assistance of a laser and is called a laser assisted uvulo-palato-plasty
(LAUPP). In other cases, a radio-frequency probe is utilized to tighten the soft
palate. These procedures usually performed under IV sedation in the office.
In more complex 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.
OSA is a very serious condition that needs careful attention and treatment. Most
major medical plans offer coverage for diagnosis and treatment.
