Learning About Tinnitus
January 24, 2011
Tinnitus is a ringing, swishing, or other type of noise that seems to originate in the
ear or head. In many cases it is not a serious problem, but rather a nuisance that
eventually resolves. Rarely, however, tinnitus can represent a serious health condition.
It is not a single disease, but a symptom of an underlying condition. Nearly 36 million
Americans suffer from this disorder. In almost all cases, only the patient can hear the
noise.
What Causes Tinnitus?
Tinnitus can arise in any of the following areas: the outer ear, the middle ear, the
inner ear, or by abnormalities in the brain. Some tinnitus or head noise is normal. If
one goes into a sound proof booth and normal outside noise is diminished, one becomes
aware of these normal sounds. We are usually not aware of these normal body sounds,
because outside noise masks them. Anything, such as ear wax or a foreign body in the
external ear, that blocks these background sounds will cause us to be more aware of our
own head sounds. Fluid, infection, or disease of the middle ear bones or ear drum
(tympanic membrane) can also cause tinnitus.
One of the most common causes of tinnitus is damage to the microscopic endings of the
hearing nerve in the inner ear. Advancing age is generally accompanied by a certain
amount of hearing nerve impairment, and consequently chronic tinnitus.
Today, loud noise exposure is a very common cause of tinnitus, and it often damages
hearing as well. Unfortunately, many people are unconcerned about the harmful effects
of excessively loud noise, firearms, and high intensity music.
Some medications (for example, aspirin) and other diseases of the inner ear (Meniere's
syndrome) can cause tinnitus. Tinnitus can in very rare situations be a symptom of such
serious problems as a brain aneurysm or a brain tumor (acoustic tumor).
How is Tinnitus Evaluated?
A medical history, physical examination, and a series of special tests can help
determine precisely where the tinnitus is originating. It is helpful for the doctor to
know if the tinnitus is constant, intermittent or pulsating (synchronous with the
heart beat, referred to as pulsatile tinnitus), or is it associated with hearing loss
or loss of balance (vertigo). All patients with persisting unexplained tinnitus need
a hearing test (audiogram). Patterns of hearing loss may lead the doctor to the
diagnosis.
Other tests, such as the auditory brain stem response (ABR), a computerized test of
the hearing nerves and brain pathways, computer tomography scan (CT scan) or, magnetic
resonance imaging (MRI scan) may be needed to rule out a tumor occurring on the hearing
or balance nerve. These tumors are rare, but they can cause tinnitus.
What is The Treatment of Tinnitus?
After a careful evaluation, your doctor may find an identifiable cause and be able to
treat or make recommendations to treat the tinnitus. Once you have had a thorough
evaluation, an essential part of treatment is your own understanding of the tinnitus
(what has caused it, the person's specific symptoms, and options for treatment).
Tinnitus Medications
In many cases, there is no specific treatment for tinnitus. It may simply go away on
its own, or it may be a permanent disability that the patient will have to "live with."
Some otolaryngologists (ear specialists) have recommended niacin to treat tinnitus.
However, there is no scientific evidence to suggest that niacin helps reduce tinnitus,
and it may cause problems with skin flushing.
The drug
gabapentin (Neurontin, Gabarone), was studied in high doses, and reduced the
annoyance level of the tinnitus in some patients, but did not decrease the volume of
the noise, and was not found to be better than placebo.
A 2005 study in Brazil using acamprosate (Campral), a drug used to treat alcoholism,
showed a nearly 87% rate of relief of symptoms. Studies of this drug for treatment
of tinnitus are currently ongoing in the United States.
What Are Tinnitus Relief Remedies?
Some common and easy remedies such as the following may be of benefit to some
individuals.
-
Reducing or avoiding caffeine and salt intake, and quitting smoking may help relieve
tinnitus symptoms.
-
Some tinnitus patients have been found to have lower zinc levels and may benefit from zinc
supplementation.
-
One study showed melatonin may help tinnitus sufferers, particularly those with
disturbed sleep due to the tinnitus. However, this is not yet been verified in
controlled studies.
-
Ginkgo Biloba has been touted as a natural tinnitus remedy, but controlled studies to
date have not shown it to be effective.
-
There are some behavioral and cognitive therapies that have been successful in treating
tinnitus. Seeking out a multidisciplinary program at a tinnitus center may improve chances
of successful treatment. The types of therapies include tinnitus retraining therapy,
masking, and behavioral therapy.
Can Tinnitus Be Prevented?
Do not place objects in your ear such as cotton swabs (Q-tips) to clean your ear. This
can cause a wax impaction against your eardrum which can cause tinnitus. Take blood
pressure medicines and other prescribed medications as they are ordered by your doctor.
According to the American Tinnitus Association there are several things you can do to
protect yourself from excessive noise related tinnitus:
-
Protect your hearing at work. Your work place should follow Occupational Safety & Health
Administration (OSHA) regulations. Wear ear plugs or earmuffs and follow hearing
conservation guidelines set by your employer.
-
When around any noise that bothers your ears (a concert, sporting event, hunting) wear
hearing protection or reduce noise levels.
-
Even everyday noises, such as blow drying your hair or using a lawnmower, can require
protection. Keep ear plugs or earmuffs handy for these activities.
