Sensorineural deafness is a type of hearing loss. It occurs from damage to the inner ear, the nerve that runs from the ear to the brain (auditory nerve), or the brain.
Symptoms may include:
Other symptoms include:
The inner part of the ear contains tiny hair cells (nerve endings), that change sounds into electric signals. The nerves then carry these signals to the brain.
Sensorineural hearing loss (SNHL) is caused by damage to these special cells, or to the nerve fibers in the inner ear. Sometimes, the hearing loss is caused by damage to the nerve that carries the signals to the brain.
Sensorineural deafness that is present at birth (congenital) is most often due to:
Sensorineural hearing loss may develop in children or adults later in life (acquired) as a result of:
In some cases, the cause is unknown.
What to Expect at Your Office Visit
The goal of treatment is to improve your hearing. The following may be helpful:
A cochlear implant may be recommended for certain people with very severe hearing loss. Surgery is done to place the implant. The implant makes sounds seem louder, but does not restore normal hearing.
