Sudden Hearing Loss
Why sudden hearing loss occurs is usually unknown. A few people have an obvious cause (such as severe head injury or infection or use of drugs that can damage hearing). In a very few people, sudden hearing loss is the first sign of an underlying disorder. Doctors do audiometry, CT and MRI, and other tests for suspected causes. Treatment is focused on known causes of the sudden hearing loss.
