Auditory neuropathy is a rare type of hearing loss.
It is caused by disruption of the nerve impulses travelling from the inner ear to the brain, although what causes this is unknown, and there is no cure.
Can nerve damage in the ear be repaired?
No surgery can repair damage to the sensory hair cells themselves, but there is a surgery that can bypass the damaged cells. Adults and children with severe to profound sensorineural hearing loss may be able to have partial hearing restored with a cochlear implant.
What are the symptoms of nerve damage in the ear?
- Hearing loss, usually gradual — although in some cases sudden — and occurring on only one side or more pronounced on one side.
- Ringing (tinnitus) in the affected ear.
- Unsteadiness, loss of balance.
- Dizziness (vertigo)
- Facial numbness and very rarely, weakness or loss of muscle movement.
What causes nerve damage in ears?
An ear infection, trauma, a tumor, or fluid or an object in the ear (such as wax buildup) can cause it. Sensorineural hearing loss happens most often from damage to the hair cells in the inner ear. Other causes include damage to the nerve for hearing, called the auditory nerve, or the brain.
What causes cochlear nerve damage?
Many things can cause SNHL, or cochlear damage, including loud or extended noise exposure, certain powerful antibiotics, men- ingitis, Meniere’s disease, acoustic tumors, and even the natural decline in age can cause hearing loss.
