The Causes Of Hearing Loss
The outer ear
Typical conditions which may lead to hearing loss include
excessive accumulation of earwax and infections of the ear canal.
The middle ear
Perforation of the eardrum, an infection or fluid in the middle
ear are the most common causes of hearing loss in the middle ear. Many outer and middle ear problems can be treated by a doctor.
In cases where treatment is not effective, remaining
hearing loss can usually be helped by using hearing aids. Hearing loss caused by conditions of the outer or middle ear
is referred to as a conductive hearing loss.
The inner ear
The majority of hearing problems result from damage to the
inner ear. Typical causes are the natural ageing process, excessive exposure to noise, medication that is toxic to the auditory system and head injuries.
Generally, hearing loss resulting from inner ear damage cannot be reversed by medical treatment, but can largely be improved with hearing aids. This type of hearing loss is referred to as a sensorineural hearing loss.
