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]
- Disease of the blood vessels
- Immune disease
- Infections, such as meningitis, mumps, scarlet fever, and measles
- Injury to the inner ear or nerve
- Meniere disease
- Tumor, such as acoustic neuroma
- Use of certain medications
- Exposure to loud noises frequently
Risk factors[edit]
Common risk factors include Occupational or recreational noises, especially if loud. Other risk factors include:
- Aging
- Heredity
- Certain medication
- Infections
Signs and symptoms[edit]
- Reduced or loss of hearing
- Difficulty understanding speech
- Sudden or steady loss of hearing
- Stuffy sensation in the ear
- Ringing in the ear
- Dizziness
Diagnosis[edit]
- 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[edit]
Treatment depends on the cause and severity and may involve some of the following:
- Hearing aids - limited value in true sensorineural hearing loss
- Cochlear or brainstem implants
- Other assistive devices
Supportive treatments include:
- vitamins and antioxidants
- vasodilators
- betahistine (Betaserc) (anti-vertigo drug)
- hyperbaric oxygen
- rheologic agents such as hydroxyethyl starch, dextran and pentoxifylline
- anti-inflammatory agents
- corticosteroids
- intratympanic administration of certain medicine
Prevention[edit]
Reducing exposure to loud sounds etc.
Prognosis[edit]
Prognosis is guarded
