Directions Site Map Find a Doctor Press Room ... Contact Us The menu has downgraded. It is at the bottom of this page. Otosclerosis Otosclerosis is an abnormal, microscopic growth of bone in the walls of the inner ear which causes the stapes bone, commonly called the "stirrup," to become frozen in place or "fixed." Normally the stapes, the smallest bone in the body, vibrates freely to allow the transmission of sound into the inner ear. When it becomes fixed to the surrounding bone, it prevents sound waves from reaching the inner ear fluids and thus hearing is impaired. What is otosclerosis? In a normal ear, sound which consists of vibrations of air molecules is funneled by the auricle, or "outer ear," through the ear canal to the ear drum. Movements of the ear drum are transferred to the ossicles, the small bones of the middle ear, and the stapes vibrates in and out of the oval window. The vibration of the stapes sets up a movement of the inner ear fluids. This, in tum, stimulates the fine sense organs of the inner ear which then stimulate the auditory (hearing) nerve which carries the sound energy to the brain. It is this sequence of events that results in normal hearing. How is otosclerosis treated?

Otosclerosis is a primary disease of the otic capsule and the ossicles. It is not known to occur outside the human temporal bone. It is characterized by a progressive hearing loss that may be conductive, sensorineural, or mixed. Histologically, it is seen as abnormal resorption and then deposition of bone in the labyrinthine capsule and middle ear. Otosclerosis is an important cause of auditory and, to a lesser extent, vestibular symptoms, and both can be treated effectively in most cases.

At What Point Should Someone Seek An Ear Specialist For Vertigo? May 01, 2000 What Is Otosclerosis And What's The Treatment? Otosclerosis is a unique disease of the bone of the inner ear that also affects the bone of the middle ear. It tends to run in families, although the exact genetic mechanism is still unknown. It's as if the bone undergoes remodeling, changing its shape and dimensions and in effect, changing its function. The bone becomes fixed in place, no longer moves as it should and doesn't work quite as well. This causes a conductive hearing loss that is almost always progressive. We have no known cure for the disease itself. Certain medications, such as fluoride, can slow the process down considerably, but they can't reverse it.

Hearing Disorders Otosclerosis Otosclerosis is a common cause of hearing impairment and is hereditary. Someone in earlier generations of your family had the condition and passed it down to you. Similarly, your descendants may inherit this tendency from you, although the hearing impairment may not manifest itself for a generation or two. Being hereditary, diseases such as scarlet fever, ear infection, and influenza have no relationship to the development of otosclerosis. Types of Hearing Impairment Hearing Impairment from Otosclerosis Tinnitus Treatment of Otosclerosis ... General Comments TYPES OF HEARING IMPAIRMENT The external ear and the middle ear conduct sound; the inner ear receives it. If there is some difficulty in the external or middle ear, a conductive hearing impairment occurs. If the trouble lies in the inner ear, a sensorineural or nerve hearing impairment is the result. When there is difficulty in both the middle and the inner ear, a mixed or combined impairment exists. Mixed impairments are common in otosclerosis.

This suggested strongly HLA related component to the disease. Further HLA-A9 and HLA-A11 levels in patients with family history suggests genetic heterogenicity. Why HLA-A3 levels were significantly higher in females than males remain unknown. Otosclerotic, a genetic disease was always known.

AFPAM-48-132 Updated-2/00 By Major Gee CONDITION: OTOSCLEROSIS / STAPEDECTOMY / STAPEDOTOMY I. Overview : Otosclerosis (“hardening of the ear”) is a bony disorder of the otic capsule that may lead to conductive and in rare cases sensorineural hearing loss due to abnormal bone deposition. It exists in 8-10% of the caucasian population, is rarer among Asian and African populations, and accounts for approximately 1% of conductive hearing loss in the caucasian population. The disease shows a familial tendency with about 60% of patients with clinical otosclerosis having a positive family history. Sites of predilection for otosclerotic involvement are: 1) just anterior to the oval window, and 2) the border of the round window of the otic capsule. The incidence of bilateral involvement is about 75-85%. The most classical clinical manifestation of this disease is conductive hearing loss secondary to stapedial fixation due to otosclerotic changes in the area of the oval window. Mainstay of treatment has traditionally been stapedectomy surgery (removal of the entire footplate) , however the newer stapedotomy (small fenestration of the footplate) technique is currently favored. Tinnitus has been reported present in 79 % of otosclerosis patients and vestibular involvement has a reported prevalence of 7-30%.

A more accurate term for this is otospongiosis, which means spongy bone. This disorder often occurs in the bones, between middle and the inner ear. The stapes is a tiny middle ear bone that transmits sound waves by banging on another area, like a stick on a drum creates sound. Otosclerosis can cause the stapes to become fixed, so that it cannot "beat on" the drum. Many people are unaware they have otosclerosis. When it affects the inner ear, nerve deafness and dizziness may result. One or both ears may be affected. It is almost always accompanied by ringing in the ear, which is called tinnitus. About one million people in the U.S. are affected by this hereditary ear disorder. It may occur in childhood, but hearing loss does not occur until a person is 20 to 40 years old. It is mostly seen in white women and may become active during pregnancy. It is also one of the leading causes of hearing loss in the elderly.

Home Hearing loss Types of hearing loss Back Otosclerosis The most common cause of conductive hearing loss in adults is otosclerosis. About 10% of the entire population has otosclerosis but only 10% of those have hearing loss as a result. The loss results from fixation of the stapes (the third bone in the middle ear) so that sounds cannot be transported to the inner ear . Otosclerosis is thought to be an inherited condition. It usually begins in early adulthood and progresses slowly, typically causing up to a 60 dB loss in both ears. Surgical treatment is very effective, with over 90% of patients achieving normal hearing levels. UT Physicians Email comments to webmaster@ucplus.org Visit www.UTdocs.com

What You Should Know About Hearing Loss Consumer Guides Coping with Hearing Loss: This Much Is Clear Hearing loss is often accompanied by feelings of isolation, despair, shame and profound frustration. Millions of Americans are looking for ways to cope. "You're spacey. Inattentive. Preoccupied. . . . Everything but hard of hearing," says Carren Stika, with dog Bailey. Stika is director of research for a San Diego rehabilitation center for people with hearing problems. PHOTOGRAPHER: GARY FRIEDMAN / Los Angeles Times Stika hadn't heard the garbled buzz of the in-flight announcement, so she hadn't known about the unscheduled touchdown in Cleveland. A fuzzy speech signal; the fuzzy ability of her ears to hear. Combining to confound her again. "Every one of us has stories like that," says Stika, who, years after the airport incident, is a director of research for a San Diego rehabilitation center for people with hearing problems. By "us," Stika means the hard of hearing, a condition she first knew she had at age 20, when she sat crying in the specialist's office with her hearing loss newly diagnosed. But her hearing loss likely dates back much further. That's why her school report cards would come home with comments like "Needs to listen more carefully." Why she had a lisp as a kid. Why college friends would tell her she sometimes seemed stuck-up or out of it, because she would "ignore" folks who said hi, fail to laugh at jokes or chime in on conversations in off-kilter ways.
