-
- Tinnitus is the perception of sound such as a ringing in the ears, in the
- absence of an acoustic stimulus. The disorder may be caused by a variety of
- ear problems including obstruction, infections, Meniere's disease, certain
- medications and head injuries.
-
- Symptoms
-
- A patient afflicted with Tinnitus may hear buzzing, ringing, roaring,
- whistling, or hissing sound without any external acoustic stimuli present.
- Sometimes the disorder may involve more complex sounds which vary over time.
- Symptoms of Tinnitus may be intermittent or continuous. An associated
- hearing loss is often present when symptoms occur, and can become permanent
- in severe cases.
-
- Causes
-
- Tinnitus may occur as a symptom of many disorders of the ear. It may be due
- to an obstruction of the external auditory canal due to ear wax and foreign
- bodies, infections (i.e., external otitis, myringitis, otitis media,
- labyrinthitis, petrositis, syphilis, and meningitis), eustachian tube
- obstruction, otosclerosis, Meniere's disease, arachnoiditis, and
- cerebellopontine angle tumors. The side effects of medications such as
- aspirin, quinine and its synthetic analogs, aminoglycoside antibiotics, and
- certain diuretics may also result in tinnitus. Carbon monoxide, heavy
- metals, alcohol, etc., cardiovascular diseases (i.e., hypertension,
- arteriosclerosis), anemia, and hypothyroidism may also cause tinnitus.
- Hereditary sensorineural hearing loss, noise-induced hearing loss, acoustic
- trauma (blast injury), or head injuries may also produce these symptoms.
-
- Related Disorders
-
- Bruit is a noise which may be heard by the examiner and sometimes by the
- patient; e.g., noise from rapid blood flow in a blood vessel. In some mental
- illnesses such as schizophrenia, a patient may hear imaginary sounds
- (hallucinations).
-
- Therapies: Standard
-
- If the tinnitus occurs as the result of an underlying disease, treatment of
- the primary disorder may improve the tinnitus. Some patients may obtain some
- relief from using a tinnitus masker, a device worn like a hearing aid that
- presents a noise more pleasant than that associated with Tinnitus. However,
- there is no medical procedure or drug at this time which can alter the
- unpredictable course of tinnitus when it is not associated with a treatable
- primary disease process.
-
- Therapies: Investigational
-
- A surgical procedure using microsurgical techniques is often suggested in the
- most severe cases of Tinnitus. The surgery seeks to relieve pressure on the
- hearing part of the eighth cranial nerve. For more information on this type
- of surgery, physycians may contact her at:
