Severe Hearing Loss: Its Causes and Treatment

 

Ongoing Exposure to Noise on the Job

Long-term exposure to continuous loud noise can cause lasting hearing loss. A common culprit is workplace noise, like machinery. About 30 million Americans face hazardous levels of noise at work. Things like motorcycles and power tools also can damage hearing over time. If you can, avoid or take breaks from noisy activities. Wear earplugs or ear protectors that fit over the ear.

Injury or Pressure Changes

Severe head trauma can dislocate middle-ear bones or cause nerve damage, causing permanent hearing loss. Sudden changes in pressure -- from flying or scuba diving -- can lead to damage to the eardrum, middle ear, or inner ear and hearing loss. Eardrums usually heal in a few weeks. In serious cases of inner ear damage, you may need surgery. Sticking cotton swabs or other objects into your ear is a bad idea. Doing so can rupture your eardrum and cause permanent damage.

Medicine

Some medicines are known to cause hearing loss as a potential side effect. These include certain antibiotics and cancer drugs. Often hearing is monitored during these treatments. However, some hearing loss may be permanent. Regular use of aspirin, NSAIDs, and acetaminophen can increase the risk of hearing loss. But hearing-related side effects go away when you stop taking the medications in some cases.

Chronic Disease

Certain chronic diseases that are not directly related to the ear can cause hearing loss. Some cause harm by interrupting blood flow to the inner ear or the brain. These conditions include heart disease, stroke, high blood pressure, and diabetes. Autoimmune diseases, such as rheumatoid arthritis, also can be linked to some forms of hearing loss.
