What is the pathophysiology of otosclerosis?

Otosclerosis is a bone disorder of unknown etiology confined to the otic capsule. Failure of remodeling of newly formed vascular, woven bone (otospongiosis) results in sclerotic bone (otosclerosis) with abnormal osteons. Involvement of the oval window causes conductive hearing loss.

How common is cochlear otosclerosis?

A bony ankylosis (knee) knits the bone of the middle ear to the stapes, preventing normal transmission of sound from the eardrum into the inner ear. Only about 0.3% of the population has otosclerosis (Donaldson and Snyder, 1993), and the percentage is going downward.

What is the type of otosclerosis?

Otosclerosis is categorised into two types, fenestral and retrofenestral/cochlear. Retrofenestral otosclerosis rarely occurs without fenestral involvement; hence these manifestations are considered to be a continuum rather than two separate entities [1–4].

What is otosclerosis Google Scholar?

Definition. Otosclerosis is a localized disease of the bone, derived from the otic capsule and characterized by alternating phases of bone resorption and formation. The term “otosclerosis” was introduced by Politzer in 1894 and refers to the final stage of a disease where the bone has become sclerotic and hardened.

What is the procedure to correct for otosclerosis?

Surgery — Surgery can be a highly effective treatment for otosclerosis. The procedure is called a “stapedectomy” (or “stapedotomy”). The procedure is intended to “bypass” the fixed part of the stapes bone by removing it, and replacing it with a new, mobile, prosthetic bone.

What type of hearing loss is otosclerosis?

Otosclerosis is a form of conductive hearing loss. In some cases, as the ear loses its ability to transmit sound, people may first notice low-frequency hearing loss, meaning that low-pitched sounds are harder to hear.

Can you go deaf from otosclerosis?

Otosclerosis can cause mild to severe hearing loss, but it very rarely causes total deafness. Your hearing usually gets worse gradually over months or a few years, and may continue to get worse if ignored and left untreated. But the hearing loss can normally be treated successfully with either hearing aids or surgery.

Does otosclerosis affect balance?

The loss may appear very gradually. Many people with otosclerosis first notice that they cannot hear low-pitched sounds or they can no longer hear a whisper. In addition to hearing loss, some people with otosclerosis may experience dizziness, balance problems, or tinnitus.

Can otosclerosis go away?

Otosclerosis cannot be cured, but the hearing loss it causes can be overcome.

How quickly does otosclerosis progress?

The hearing loss from otosclerosis is usually progressive over many years. Both ears are often affected, although one ear is usually worse than the other. The hearing loss may progress during pregnancy and (possibly) with certain types of hormonal treatment.

How do you get otosclerosis?

What causes otosclerosis? Otosclerosis is most often caused when one of the bones in the middle ear, the stapes, becomes stuck in place. When this bone is unable to vibrate, sound is unable to travel through the ear and hearing becomes impaired (see illustration).

What is the best treatment for otosclerosis?

    What is otosclerosis and treatment?

    What are the treatment options for otosclerosis? Hearing aids. At first, when the hearing loss is mild, you may not need any treatment. Surgery. The most common operation that is done is to replace the stapes with an artificial bone made of plastic or metal. Fluoride tablets. Hormone tablets and the contraceptive pill.

    How is Otosclerosis treated?

    Treatments for otosclerosis. Otosclerosis can usually be treated successfully with either a hearing aid or surgery. If your hearing loss is very mild, you may not need any treatment at first.
