Sleep
Disorders

Forty-five percent of normal adults snore at least
occasionally, and 25 percent are habitual snorers.
Problem snoring is more frequent in males and overweight
persons, and it usually grows worse with age.
More than 300 devices are registered in the U.S.
Patent and Trademark Office as cures for snoring. Some
are variations on the old idea of sewing a sock that
holds a tennis ball on the pajama back to force the
snorer to sleep on his side. (Snoring is often worse
when a person sleeps on his back). Some devices
reposition the lower jaw forward; some open nasal air
passages; a few others have been designed to condition a
person not to snore by producing unpleasant stimuli when
snoring occurs. However, if you snore, the truth is that
it is not under your control whatsoever. If anti-snoring
devices work, it is probably because they keep you
awake.
What Causes Snoring?
The noisy sounds of snoring occur when there is an
obstruction to the free flow of air through the passages
at the back of the mouth and nose. This area is the
collapsible part of the airway (see illustration) where
the tongue and upper throat meet the soft palate and
uvula. Snoring occurs when these structures strike each
other and vibrate during breathing.
People who snore may suffer from:
- Poor muscle tone in the tongue and throat. When
muscles are too relaxed, either from alcohol or
drugs that cause sleepiness, the tongue falls
backwards into the airway or the throat muscles draw
in from the sides into the airway. This can also
happen during deep sleep.
- Excessive bulkiness of throat tissue. Children
with large tonsils and adenoids often snore.
Overweight people have bulky neck tissue, too. Cysts
or tumors can also cause bulk, but they are rare.
- Long soft palate and/or uvula. A long palate
narrows the opening from the nose into the throat.
As it dangles, it acts as a noisy flutter valve
during relaxed breathing. A long uvula makes matters
even worse.
- Obstructed nasal airways. A stuffy or blocked
nose requires extra effort to pull air through it.
This creates an exaggerated vacuum in the throat,
and pulls together the floppy tissues of the throat,
and snoring results. Therefore, snoring often occurs
only during the hay fever season or with a cold or
sinus infection.
In addition, deformities of the nose or nasal septum,
such as a deviated septum (a deformity of the wall that
separates one nostril from the other) can cause such an
obstruction.
Is Snoring Serious?
Socially, yes! It can be, when it makes the snorer an
object of ridicule and causes others sleepless nights
and resentfulness.
Medically, yes! It disturbs sleeping patterns and
deprives the snorer of appropriate rest. When snoring is
severe, it can cause serious, long-term health problems,
including obstructive sleep apnea.
Obstructive Sleep Apnea
When loud snoring is interrupted by frequent episodes
of totally obstructed breathing, it is known as
obstructive sleep apnea. Serious episodes last more than
ten seconds each and occur more than seven times per
hour. Apnea patients may experience 30 to 300 such
events per night. These episodes can reduce blood oxygen
levels, causing the heart to pump harder.
The immediate effect of sleep apnea is that the
snorer must sleep lightly and keep his muscles tense in
order to keep airflow to the lungs. Because the snorer
does not get a good rest, he may be sleepy during the
day, which impairs job performance and makes him a
hazardous driver or equipment operator. After many years
with this disorder, elevated blood pressure and heart
enlargement may occur.
Can Heavy Snoring be Cured?
Heavy snorers, those who snore in any position or are
disruptive to the family, should seek medical advice to
ensure that sleep apnea is not a problem. An
otolaryngologist will provide a thorough examination of
the nose, mouth, throat, palate, and neck. A sleep study
in a laboratory environment may be necessary to
determine how serious the snoring is and what effects it
has on the snorer's health.
Treatment
Treatment depends on the diagnosis. An examination
will reveal if the snoring is caused by nasal allergy,
infection, deformity, or tonsils and adenoids.
Snoring or obstructive sleep apnea may respond to
various treatments now offered by many
otolaryngology’s-head and neck surgeons:
- Uvulopalatopharyngoplasty (UPPP) is surgery for
treating obstructive sleep apnea. It tightens flabby
tissues in the throat and palate, and expands air
passages.
- Thermal Ablation Palatoplasty (TAP) refers to
procedures and techniques that treat snoring and
some of them are used to treat various severities of
obstructive sleep apnea. Different types of TAP
include bipolar cautery, laser, and radiofrequency.
Laser Assisted Uvula Palatoplasty (LAUP) treats
snoring and mild obstructive sleep apnea by removing
the obstruction in the airway. A laser is used to
vaporize the uvula and a specified portion of the
palate in a series of small procedures in a doctor's
office under local anesthesia. Radiofrequency
ablation—some with temperature control approved by
the FDA—utilizes a needle electrode to emit energy
to shrink excess tissue to the upper airway
including the palate and uvula (for snoring), base
of the tongue (for obstructive sleep apnea), and
nasal turbinates (for chronic nasal obstruction).
- Genioglossus and hyoid advancement is a surgical
procedure for the treatment of sleep apnea. It
prevents collapse of the lower throat and pulls the
tongue muscles forward, thereby opening the
obstructed airway. If surgery is too risky or
unwanted, the patient may sleep every night with a
nasal mask that delivers air pressure into the
throat; this is called continuous positive airway
pressure or "CPAP".
A chronically snoring child should be examined for
problems with his or her tonsils and adenoids. A
tonsillectomy and adenoidectomy may be required to
return the child to full health.
Self-Help for the Light Snorer
Adults who suffer from mild or occasional snoring
should try the following self-help remedies:
- Adopt a healthy and athletic lifestyle to
develop good muscle tone and lose weight
- Avoid tranquilizers, sleeping pills, and
antihistamines before bedtime
- Avoid alcohol for at least four hours and heavy
meals or snacks for three hours before retiring
- Establish regular sleeping patterns
- Sleep on your side rather than your back
- Tilt the head of your bed upwards four inches.
Remember, snoring means obstructed breathing, and
obstruction can be serious. It is not funny, and not
hopeless.
