Snoring: Not Funny, Not Hopeless
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. But, 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. So, snoring often occurs only during the hay fever season or
with a cold or sinus infection.
Also, 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 otolaryngologist-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 also 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 hyod 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's not funny, and not hopeless.
