- Sensorineural hearing loss can result from acoustic trauma (or exposure to excessively loud noise), which may respond to medical therapy with corticosteroids to reduce cochlea hair cell swelling and inflammation to improve healing of these injured inner ear structures.
- Sensorineural hearing loss can occur from head trauma or abrupt changes in air pressure such as in airplane descent, which can cause inner ear fluid compartment rupture or leakage, which can be toxic to the inner ear. There has been variable success with emergency surgery when this happens.
- Sudden sensorineural hearing loss, presumed to be of viral origin, is an otologic emergency that is medically treated with corticosteroids.
- Bilateral progressive hearing loss over several months, also diagnosed as autoimmune inner ear disease, is managed medically with long-term corticosteroids and sometimes with drug therapy. Autoimmune inner ear disease is when the body’s immune system misdirects its defenses against the inner ear structures to cause damage in this part of the body.
- Fluctuating sensorineural hearing loss may be from unknown cause or associated with Meniere’s Disease. Symptoms of Meniere’s disease are hearing loss, tinnitus (or ringing in the ears), and vertigo. Meniere’s disease may be treated medically with a low-sodium diet, diuretics, and corticosteroids. If the vertigo is not medically controlled, then various surgical procedures are used to eliminate the vertigo.
- Sensorineural hearing loss from tumors of the balance nerve adjacent to the hearing nerve, generally are not reversed with surgical removal or irradiation of these benign tumors. If the hearing loss is mild and the tumors are very small, hearing may be saved in 50 percent of those undergoing hearing preservation surgery for tumor removal.
- Sensorineural hearing loss from disease in the central nervous system may respond to medical management for the specific disease affecting the nervous system. For example, hearing loss secondary to multiple sclerosis may be reversed with treatment for multiple sclerosis.
- Irreversible sensorineural hearing loss, the most common form of hearing loss, may be managed with hearing aids. When hearing aids are not enough, this type of hearing loss can be surgically treated with cochlear implants.
