Snoring & Sleep Apnea
Snoring:
Some
45 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 tennis ball on the pajama back - to
force the snorer to sleep on his side. (Snoring is often
worse when the person sleeps on his back). Chin and
head straps, neck collars, and devices inserted into
the mouth are usually disappointing as snoring cures.
Many electrical devices have been designed to produce
painful or unpleasant stimuli when the patient snores.
The presumption was that a person could be trained or
conditioned not to snore. Unfortunately, snoring is
not under the person's control whatsoever; and if these
devices work it is probably because they keep the snorer
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 is the collapsible
part of the airway where the tongue and upper throat
meet the soft palate and uvula (the fleshy structure
that dangles from the roof of the mouth back into the
throat). When these structures strike against each other
and vibrate during breathing, that is snoring. Persons
who snore have at least one of the following problems:
Poor muscle tone (lack of tightness) in the muscles
of the tongue and throat. Flabby muscles allow the tongue
to fall backwards into the airway or allow the throat
muscles to be drawn in from the sides into the airway.
This occurs when the person's muscular control is too
relaxed from alcohol or from drugs which cause sleepiness.
It also happens in some persons when they relax in the
deep-sleep stages.
Excessive bulkiness of tissues of the throat.
Large tonsils and adenoids, for example, commonly cause
snoring in children. Overweight persons also have bulky
neck tissues. Cysts or tumors could also be present,
but they are rare.
Excessive length of the soft palate and uvula.
A long palate may narrow the opening from the nose into
the throat. As it dangles in the airway, the soft palate
with its attached uvula acts as a flutter valve during
relaxed breathing, and contributes to the noise of snoring.
A long uvula makes matters even worse.
Obstructed nasal airways. When a person has a
stuffy or blocked-up nose he must pull hard to inhale
air through it. This creates an exaggerated vacuum in
his throat, in the collapsible part of the airway, and
it pulls together the floppy tissues of the throat.
So snoring occurs even in persons who would not snore
if they could breathe through the nose properly. This
explains why some people snore only during the hay fever
season, or when they have a cold or sinus infection.
Also, deformities of the nose or nasal septum frequently
cause such obstruction. "Deviated septum"
is a common term for a deformity inside the nose in
the wall that separates one nostril from the other.
Is Snoring Serious?
Socially - yes. It is disruptive to family life.
It makes the snorer an object of ridicule and causes
other household members sleepless nights and resentfulness.
Snorers become unwelcome roommates on vacations or business
trips.
And medically - yes. It disturbs the sleeping
patterns of the snorer himself, so that he may not sleep
restfully. Furthermore, heavy snorers tend to develop
high blood pressure at a younger age than non-snorers.
The most exaggerated form of snoring is known as obstructive
sleep apnea, when loud snoring is interrupted by frequent
episodes of totally obstructed breathing. This is serious
if the episodes last over 10 seconds each and occur
more than 7 times per hour. Your physician may recommend
a laboratory sleep study as a way of evaluating your
symptoms. Apnea patients may experience 50 to 500 obstructed
events per night, and many spend as much as half their
sleep time with blood oxygen levels below normal. During
the obstructive episodes, the heart muscle may not receive
sufficient oxygen resulting in irregular heartbeats
that may be life threatening. Each apnea (obstructed
breathing) episode ends when the brain wakes up the
person enough so that he begins breathing again. The
sleeper is unaware of his frequent awakenings because
they only last for a few seconds but the result is that
the person never progresses to deeper stages of sleep.
Persons with obstructive sleep apnea may spend little
of their night-time hours in the deep sleep stages that
are essential for a good rest. Therefore, in the morning
they awaken unrefreshed and are sleepy much of the day.
They may fall asleep while driving to work or while
on the job.
Since snorers with severe sleep apnea are often unaware
of it, a laboratory sleep study may be the only way
to discover it.
Can Snoring Be Cured?
Remember, snoring means obstructed breathing, and obstruction
can be serious. It's not funny, and it is definitely
not hopeless.
Every child who snores should be thoroughly examined
by a physician. Medical evidence suggests that a tonsillectomy
and adenoidectomy will probably make an important difference
in the health and well-being of the child.
Snoring adults should be examined to determine the seriousness
of the problem. Treatment will depend, of course, on
the diagnosis. It may be as simple as managing nasal
allergies or infection. In other cases, it may require
surgery to correct a nasal deformity or to remove large
tonsils or an enlarged uvula. Many snorers respond best
to surgery on the throat to remove flabby tissue and
expand the airway. There are other non-surgical approaches
that can be performed in the office setting which essentially
are treatments designed to cause scarring and thus stiffening
of the soft palate. These include somnoplasty and snoreplasty.

to discuss the right option for you!
