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 air flow 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.
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 individuals 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 a uvulo-palato-pharyngo-plasty
(UPPP), which is performed in the back of the soft palate and throat. A
similar procedure is sometime done with the assistance of a laser and
is called a Laser Assisted uvulo-palato-plasty (LAUP). In other cases, a
radio-frequency probe is utilized to tighten the soft palate. These
are procedure usually performed under light intravenous 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 1 to 2 days 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.
