Tumor
While not as common, tumors along the nerve that connects the ear to the brain or in the inner ear can cause a noticeable decline in hearing. Typically these tumors are found in people who have hearing loss in one ear, but not the other. Dizziness and vertigo are also signs that a tumor may be present. It’s important to get a comprehensive evaluation from a specialist as soon as symptoms start to determine if a tumor is causing hearing loss and treat the issue.
