A reduced sensitivity to the sounds that can be heard normally. The problem of hearing impairment / hearing loss is due to the problem in either one or more parts of the ear.
The types of hearing loss/hearing impairment can be classified by knowing which part of the auditory system has been damaged. Sensorineural hearing loss, mixed hearing loss and conductive hearing loss are the three types.
The procedure by which the fixed stapes are removed and is then replaced with a prosthesis. This procedure enables the transmission of the sound vibrations to the inner fluids of the ear for the purpose of hearing. The condition that causes the problem of stapedectomy is Otosclerosis. Otosclerosis can be hereditary or can also affect without any prior family history. It generally involves about 2 % of the population. The problem of hearing is first noticed at the age of twenties and can lead to hearing loss in the later stages of the life.
The surgical procedure is performed in which the middle ear innermost bone of the 3 bones ( Malleus, stapes and the incus) is removed. It is then replaced by a small plastic tube that surrounds a short length of wire made up of stainless steel.
The stapes fixation results in two chief causes. First is the abnormal mineralization of the otosclerosis (temporal bone) which is regarded as a disease process. The other cause is the stapes congenital malformation.
Ringing in the ears (Tinnitus) is the condition where there is no other sound. It could be the sound of roaring, pulsing, clicking, hissing, whooshing and chirping. The condition of Tinnitus can either in one or in both ears. Cure for Tinnitus is possible in few medical conditions. Otolaryngologists and audiologists are trying to identify some methods for the Tinnitus treatment.
The treatment depends on whether the hearing loss is temporary (reversible hearing loss) or permanent. The permanent hearing loss can be treated with hearing implants and devices.
The fixation of the stapes bones happens as a result of abnormal growth in the small bones of the middle ear. The proper functioning of the ear depends on the free movement of the stapes bones. The process of hearing starts by first sending sound vibrations (from the outer ear) inside the ear canal and from there the sound vibrations hit the ear drum. The movement of the ear drum causes vibrations sends the vibrations into the three tiny bones- anvil (incus), stirrup (stapes) and hammer (Malleus). The hearing (auditory) nerve is stimulated when there is a movement of the stapes bone that sets the motion of the inner ear fluids. The sound energy is then transferred by the auditory nerve in the brain that leads in sound hearing.
Otorlaryngologist can advise the use of hearing aids to increase the sound that will reach to the ear drum, provided if the hearing loss in not serious. The specialists can also advise Sodium fluoride that can slow the development of the disease. However, the most effective surgical method is Stapedectomy that improves hearing.
