Hearing loss results when there is damaged somewhere in the hearing system. It can also be caused by a simple blockage in the external or middle ear. Hearing loss is usually described as either a conductive hearing loss or a sensori-neural hearing loss.
Conductive hearing loss
Results when the cause of the problem occurs in the external or middle ear. It is often correctable by surgery. The commonest examples are:
Wax in the external canal
Blockage in the Eustachian tube
Fluid in the middle ear
Glue ear
Eardrum perforation
Otosclerosis
Sensori-neural hearing loss
Results from damage to the internal ear or to the nerves and brain. This is the most common hearing loss and is generally permanent and un-operable. The commonest causes are:
Aging (presbyacusis)
Noise damage
Oxygen deprevation
Prescribed drugs and drug misuse
Changes to the acoustic nerve due to disease
