Tinnitus
(Ringing and Other Ear Noise)

Tinnitus, Interrupted

Tinnitus Prevention

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.

What is tinnitus?

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.

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 abnormailities 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 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 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 an aneurysm or a brain tumor (acoustic tumor).

What is the temporomandibular joint?

The temporomandibular joint (TMJ) is the area directly in front of the ear on either side of the head where the upper jaw (maxilla) and lower jaw (mandible) meet. Within the TMJ, there are moving parts that allow the upper jaw to close on the lower jaw. This joint is a typical sliding "ball and socket" that has a disc sandwiched between it. The TMJ is used throughout the day to move the jaw, especially in biting and chewing, talking, and yawning. It is one of the most frequently used joints of the body.

The temporomandibular joints are complex and are composed of muscles, tendons, and bones. Each component contributes to the smooth operation of the TMJ. When the muscles are relaxed and balanced and both jaw joints open and close comfortably, we are able to talk, chew, or yawn without pain.

We can locate the TMJ by putting a finger on the triangular structure in front of the ear. The finger is moved just slightly fo...
