Causes of Sudden Hearing Loss
information and advice
The cause of sudden hearing loss is not always easy to pinpoint, by either you or a doctor. However, there are a number of possibilities.
Ear infections can frequently cause a buildup of fluid within the middle ear section. In some severe cases, the pressure of the fluid builds to the point that it ruptures the eardrum itself, causing a sudden reduction in hearing. Viral infections can also cause inflammation within the sensitive inner ear or along the auditory nerve.
Unsurprisingly, any serious head injury can cause sudden hearing loss. The violent nature of such injuries can easily damage any section of the ear, including the auditory nerve, the ear canal, the eardrum, the sensitive hair cells and the small bones of the middle ear.
If you’re attending a concert, a busy construction site or anywhere else where there is unusually loud noise, we would always recommend that you wear ear protection.
Earwax is a perfectly normal substance which helps keep your ears clean. It collects dust and dirt and moves them away from the sensitive inner ear. However, sometimes earwax can build up. This results in sudden hearing loss as sound waves can no longer travel through the ear canal. Earwax actually expands when it gets wet which is why some people’s hearing becomes muffled following a swim.
When taken in strong doses, some drugs can cause sudden hearing loss. If you are using antibiotics, anti-inflammatories or chemotherapy drugs, and begin to notice changes in your hearing, speak to your doctor right away. .
