Acute hearing loss is the sudden onset of hearing loss. It usually happens in only one ear and with no known cause. Those experiencing acute hearing loss are only able to hear muffled conversations or sounds through the affected ear. Hearing may recover slightly or completely in the days and weeks afterwards, however there is a possibility of permanent damage. The more severe the initial hearing loss, the greater the risk of permanent damage.
The potential causes of acute hearing loss include:
- certain types of medications,
- head injury, stroke, tumors, or middle ear or brain infections,
- certain viral infections,
- decreased blood supply to the inner ear and the nerve that connects the inner ear to the brain,
- an attack by the immune system,
- damage to the cells in your ear that control your sense of hearing.
Treatment options which are currently available for acute hearing loss:
- High-dose corticosteroid drug regimens or infusions that stimulate blood flow are usually prescribed for the treatment of acute hearing loss. However, the effectiveness of these treatments has not been clearly demonstrated,
- AM-111, the study drug being tested, is a novel treatment. That means it is new and different from anything that has ever been done, experienced, or made before.
- AM-111 has been developed to protect hearing cells and nerves following acute hearing loss. A clinical trial with the study drug AM-111 for acute hearing loss is currently being conducted in hospitals and ear specialists’ clinics in North America, Europe and South Korea.
- If your hearing loss started more than 72 hours ago, we advise you consult your local ear specialist or primary care doctor.
