Hearing Problems – Information & Advice
Anybody of any age can endure hearing loss or hearing disorders. The majority of hearing disorders are caused by things such as overexposure to very loud noises, genetic predispositions to ear problems and aging. Some other kinds of hearing problems can be a result of wax buildup, a ruptured eardrum, or possibly even a severe ear infection. A person who experiences hearing problems should consult a specialist doctor, who can diagnose the condition and prescribe the proper medication, supply hearing aids, or give advice on the prevention of possible future problems.
While there are varying degrees of hearing loss, there are only 3 main types depending on what part of the ear is affecting the loss of hearing. Sensorineural hearing loss is the name given to a disorder that affects the nerves leading to the ear from the brain, and the inner ear up to the ear drum. Conductive hearing loss describes any kind of hearing loss that is caused by damage or blockage in any area of the middle and outer ear. Mixed hearing loss is the name given to a disorder that comprises of sensorineural and conductive hearing loss.
When sound that is transmitted from the outer ear, through the middle ear to the ear drum, is restricted due to some sort of blockage, it is known as conductive hearing loss. The most common causes of conductive hearing loss are infections, excessive wax build up, common colds and the presence of foreign objects. More serious forms of conductive hearing loss could be caused by damage to the ear drum or Eustachian canal, or a tumor.
Problems that stem from conditions affecting the inner ear and nerves leading to the brain are categorized as forms of sensorineural hearing loss. The most common cause of hearing loss in this local area is abnormalities in the hair cells that are located in the organ of Corti in the cochlea, though it can also be caused as a result of injury to any area of the inner ear and the eighth cranial nerve. Many people experience this form of hearing loss from listening to loud music for extended periods of time.
Mixed hearing loss is categorized when a combination of conductive hearing loss and sensorineural hearing loss is experienced. This kind of hearing loss usually happens as a result of an injury to the ear or when some other form of trauma is experienced. As treatment for sensorineural hearing loss is difficult to administer and vast improvements are unlikely, doctors tend to focus their attention on treatment for conductive hearing loss instead, in this situation.
