Sensorineural hearing loss is deafness caused by damage to the inner ear or the nerve that conducts signals from the ear to the brain

Causes[edit]

Common risk factors include Occupational or recreational noises, especially if loud. Other risk factors include:

The diagnosis of a sensorineural pattern hearing loss is usually made through audiometry.
The audiometry shows a significant hearing loss without the air-bone gap seen in conductive hearing loss.
Imaging studies such as CT scan and or MRI scan to rule out tumors etc.

Treatment depends on the cause and severity and may involve some of the following:

Supportive treatments include:

Reducing exposure to loud sounds etc.

Prognosis is guarded
