What could cause sudden hearing loss in one ear?
Sudden hearing loss (also called sudden sensorineural hearing loss or SSHL) is a medical emergency that can occur when you suddenly lose your hearing in one or both ears. In many cases, the cause is unknown. However, a number of factors can increase your risk of SSHL, including:
- Ear infections, such as otitis media: These infections are one of the most common causes of SSHL, especially in children.
- Meniere's disease: This is a disorder of the inner ear that can cause SSHL, dizziness, ringing in the ears (tinnitus), and a feeling of fullness or pressure in the ear.
- Acoustic trauma: This refers to damage to the ear caused by exposure to sudden, loud noises, such as a gunshot or explosion. SSHL and tinnitus can be symptoms of acoustic trauma.
- Head trauma: A head injury can also damage the ear, causing sudden hearing loss.
- Ototoxicity: Certain medications can damage the ear and lead to SSHL. These medications include antibiotics, chemotherapy drugs, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs).
- Immune system disorders, such as lupus, multiple sclerosis, and vasculitis, can affect the ear and cause sudden hearing loss.
- Viral infections: Some viral infections, such as the mumps and measles, can cause SSHL.
If you experience sudden hearing loss, it's important to see your doctor right away. The sooner you receive treatment, the more likely you are to regain your hearing.
