Damage to the cochlea or to the nerves or parts of the brain responsible for hearing can cause permanent hearing loss. Sensorineural loss may be from birth or acquired. Some common permanent causes of deafness may be due to:

• ageing
• childhood illnesses like measles, mumps, meningitis
• tumors in the inner ear
• excessive noise exposure
• ototoxic medication
• hereditary
• vascular disorder

Early Detection is therefore vital.
