Ringing in the ear, or tinnitus, is a widespread condition that affects an estimated 50 million Americans. Some people describe it as a hissing, roaring, whooshing or buzzing sound instead of ringing. It may be sporadic or constant, and is a symptom of an underlying condition rather than a disease itself. There are many factors that can cause tinnitus.
What Are the Causes of Tinnitus?
Tinnitus is categorized as being either pulsatile or nonpulsatile.
People who suffer from pulsatile tinnitus report hearing the sound of their own pulse. It is caused by abnormal blood flow within the arteries of the neck or inside the ear, and is fairly rare.
Nonpulsatile tinnitus – ringing in the ears not accompanied by any type of rhythm – is considerably more common. It can be caused by a variety of conditions including:
- Presbycusis (age-related hearing loss).
- Noise exposure.
- Impacted earwax.
- Otosclerosis (stiffening of the bones in the middle ear).
- Meniere’s disease.
- TMJ disorders.
- Ototoxic medications.
- Thyroid conditions.
- Head or neck trauma.
- Acoustic neuromas.
Tinnitus is also classified as being either subjective (heard only by the patient) or objective (ringing can be heard by an impartial observer, such as a doctor). Most cases of tinnitus are subjective in nature.
How Is Tinnitus Treated?
Tinnitus can’t be cured, but there are treatments that make it less of a distraction. The approach taken depends on the underlying condition responsible for the ringing in your ears. Sometimes, simple steps like removing built-up earwax or switching to a new medication can markedly decrease symptoms.
Tinnitus can sometimes be reduced by improving hearing through hearing aids.
Others benefit from noise suppression therapy or masking techniques designed to cover up the ringing noise.
Brain retraining devices, which rely on patterned tones, are a newer technique that has proven beneficial to some patients.
Educational and behavioral counseling can be used to better understand and react to tinnitus.
