Sensorineural Hearing Loss
Sensorineural hearing loss is due to damage to the sensory hair cells in the cochlea of the inner ear, preventing nerve cells from sending complete signals to the brain.
Causes of sensorineural hearing loss include:
- Congenital/Hereditary – Many sufferers are born with sensorineural hearing loss or are predisposed to the condition through genetics. Congenital causes can include lack of cochlear development and congenital rubella syndrome.
- Disease and Viral Infections – A number of illnesses and infections can cause sensorineural hearing loss, including meningitis, mumps, measles and syphilis
- Noise Exposure – Prolonged exposure to sounds over 80 decibels has been shown to cause hearing loss. People who work in noisy environments, such as loud manufacturing facilities; those who live close to highways, airports or other sources of loud noise; audio headphone users and musicians are all at risk of damaged hearing due to prolonged exposure to high sound levels.
- Oto-toxic Medicines – Ototoxicity is damage to the ear. Oto-toxic medications include loop diuretics and salicylates, which includes ASA, or aspirin (in high doses).
- Trauma – A blow or injury to the head can result in damage to the ear, including inner ear concussion, or to the parts of the brain that process the hearing signals from the ear.
- Aging – Presbycusis is hearing loss due to the degeneration of cells caused by aging. Presbycusis can be compounded by any of the other causes of sensorineural hearing loss.
Sensorineaural hearing loss cannot be treated with medication or surgery. The main treatment methods are hearing aids and cochlear implants.
If you suspect you have sensorineural hearing loss, you must consult a hearing specialist as soon as possible.
