PUBLIC AREA MEMBERS LOGIN SITE MAP Printer-friendly version ... Contacts Otosclerosis by R Lloyd Faulconbridge and D Bowdler, University Hospital Lewisham What is this? It is a familial condition in which there is new bone formation around the footplate of the stapes (the smallest ossicle, which transmits the vibrations of the eardrum to the inner ear). This results in a conductive hearing loss. Sometimes there is some involvement of the inner ear, so that there is an element of sensorineural hearing loss too. Why have an operation? The operation will improve your hearing. The aim of the operation is to bypass the fixed, unmoving footplate and to use a type of plastic piston to transmit the vibrations to the cochlea (inner ear). What does the operation involve? It is almost always done under general anaesthetic. An incision is made in the skin of the ear canal and the ear drum lifted forwards The body of the stapes is removed, leaving the fixed footplate still in position. A tiny opening is made in the footplate of the stapes using a laser and a microdrill. A plastic prosthesis is placed in the opening and fixed to the arm of the incus (the second ossicle) The eardrum is relaced, and a pack put in the ear canal.

In a stapedectomy, the stapes is removed and a prosthesis is placed to transmit sound vibration from the the incus (anvil), to a fat plug (fascia or vein) in the oval window of the inner ear.

Otosclerosis is the abnormal growth of bone of the inner ear. This bone prevents structures within the ear from working properly and causes hearing loss. For some people with otosclerosis, the hearing loss may become severe. How Do We Hear? How Does Otosclerosis Cause Hearing Impairment? Otosclerosis can cause different types of hearing loss, depending on which structure within the ear is affected. Otosclerosis usually affects the last bone in the chain, the stapes, which rests in the entrance to the inner ear (the oval window). The abnormal bone fixates the stapes in the oval window and interferes with sound passing waves to the inner ear. Otosclerosis usually causes a conductive hearing loss, a hearing loss caused by a problem in the outer or middle ear. Less frequently, otosclerosis may cause a sensori-neural hearing loss (damaged sensory cells and/or nerve fibers of the inner ear), as well as a conductive hearing loss.

Otosclerosis Overview As printed in Hearing Health , volume 19:1, Spring 2003 Contributors: Howard P. House, M.D., Antonio De la Cruz, M.D., Rick A. Friedman, M.D., Ph.D., and Fred H. Linthicum, Jr., M.D. Oto means of the ear and sclerosis refers to abnormal hardening of tissue. While the root words and the description are easy to understand, the exact nature of otosclerosis and a potential cure are not yet clear. We do know that it is a common cause of hearing loss and that it occurs primarily among adults, more often among women and is most prevalent among Caucasians. It is difficult to arrive at an accurate count of the number of people who actually have the disease. Some studies show that for the ages between 30 and 50, from 10 to 18 percent of all white women and 7 to 9 percent of all white men have tissue changes in the middle ear resulting from otosclerosis. Less than 10 percent of those individuals, however, actually seek help for hearing loss. Oriental people have 50 percent fewer cases and it is very rare among blacks and Native Americans. Frequency of cases with hearing loss increases in higher age groups and it is more probable overall for women to experience impaired hearing from otosclerosis.

The mobilization era began in the late 1800s when Kessel attempted stapes mobilization without ossicular chain reconstruction in cases where it was noted to be fixed. Later, Jack removed the stapes, leaving the oval window open. Both techniques allowed increased transmission of sound through the oval window but did not use middle ear amplification structures. Furthermore, fatal cases of meningitis from intraoperative exposure of perilymph to bacteria occurred, and any gains in hearing frequently were temporary because any remaining stapes footplate often refixed. The fenestration era began in 1923, when Holmgren created a fistula in the horizontal semicircular canal and sealed it immediately with periosteum. This procedure allowed sound conduction preferentially through the fistula, rather than the ossicular chain. Sourdille popularized the procedure when his 3-stage technique was widely published during the 1930s. Lempert developed a 1-stage technique for horizontal semicircular fenestration, which went on to gain worldwide acceptance after it proved to enhance hearing. Results, however, were short-lived because the fenestra often resealed with bone. The stapedectomy era began before the fenestration era closed. Rosen revisited stapes mobilization in 1952. Later, Shea removed the stapes, sealed the oval window with an autograft vein wall, and then reconstructed the sound-conducting mechanism with an artificial prosthesis.

Ear anatomy Otosclerosis Definition Otosclerosis is an abnormal bone growth in the middle ear that causes hearing loss Alternative Names Otospongiosis Causes Otosclerosis is an inherited disorder involving the growth of abnormal spongy bone in the middle ear. This growth prevents the stapes (stirrup bone) from vibrating in response to sound waves, thus leading to progressive (worsening over time) hearing loss. Otosclerosis is the most frequent cause of middle ear hearing loss in young adults, affecting about 10% of the population of the US. Otosclerosis usually affects both ears, and is most commonly seen in women aged 15-30. Risks include pregnancy (which may trigger onset) and a family history of hearing loss. Caucasians are more susceptible than others to otosclerosis.

It is twice as common in women as in men. The middle ear cavity houses the sound-conduction mechanism called the ossicular chain, consisting of three tiny bones (ossicles) that magnify vibrations received at the eardrum for onward transmission to the inner ear. In otosclerosis, extraneous growth of spongy bone immobilizes the chain, preventing the conduction of sound. Surgery is necessary to remove the diseased bone and reconstruct the ossicular chain.

How is Otosclerosis Treated? Can I have the Operation? What are My Chances of Success? What Should I Know Before the Operation? ... What Can I Expect After the Operation? What is 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 placed 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 hearing is impaired. 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 eardrum. Movements of the eardrum are transferred to the ossicles, the small bones of the middle ear. The eardrum and ossicles act as an amplifier and transducer, changing sound into a mechanical energy. At the end of this chain, the stapes vibrates in and out of the oval window, a thin membrane between the air-filled middle ear and fluid-filled inner ear. The vibration of the stapes sets up a wave of movement of the inner ear fluids. This, in turn, stimulates the fine sense organs (the hair cells) 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.
