Tinnitus is a condition where patients experience noises they can hear that are not produced by an external source. This disorder can occur in one or both ears, range in pitch from a low roar to a high squeal, and may be continuous, pulsating, or sporadic. This often debilitating condition is commonly associated with hearing loss. Reasons for hearing loss include ear injuries, circulatory system problems, noise-induced hearing loss, wax build-up in the ear canal, medications harmful to the ear, ear infections, head and neck trauma, Ménière’s disease, and an abnormal growth of bone of the middle ear. In rare cases, slow-growing tumors on auditory, vestibular, or facial nerves can cause tinnitus as well as deafness, facial paralysis, and balance problems. The American Tinnitus Association estimates that more than 50 million Americans have tinnitus problems to some degree and approximately 12 million people have symptoms severe enough to seek medical care. This condition is not uncommon in the pediatric population. The good news is that most children seem to outgrow the condition.
Tinnitus should be evaluated by an ear, nose & throat (ENT) doctor. The ENT doctor examines you and will likely recommend a hearing test. Based on the results of the hearing test, other tests may be indicated, including balance testing, a special radiologic examination of your ear and brain called a magnetic resonance image (MRI), laboratory work, or a complicated hearing test called brainstem auditory evoked response (ABR or BAER) to evaluate the cause of the tinnitus. If a specific cause is not identified, the following list of suggestions may help lessen the severity of the tinnitus:
Tinnitus is usually more bothersome when you are in a quiet room. We recommend using a low-level background noise generator. The continuous use of background noise at a level below your head noise will eventually help habituate, or decrease the intensity of the tinnitus sound that you hear. Most people prefer using a natural sound such as a babbling brook or the sound of rain. Noise machines are sold in a variety of stores and catalogs. Others find that using a fan or humidifier will provide enough noise to help decrease their tinnitus.
There is no cure for tinnitus, even when it might be caused by pressure from a tumor. When the tumor is removed, about 50% of the time the head noise present before surgery is still present after surgery. Some people with a hearing loss notice the intensity of their tinnitus is decreased when their hearing loss is improved by surgery, or more frequently, when they get a hearing aid. Occasionally tinnitus may be so severe that it may cause or worsen a patient’s depression. Antidepressants have been shown to help severe tinnitus sufferers, and we often refer patients to skilled therapists who will manage the depression and the medications used for its treatment.
