Otosclerosis submitted by Richard A. Weinberg, M.D., F.A.C.S. A common cause of hearing loss is otosclerosis, a bone disease that occurs only in the ear and results in an overgrowth of abnormal bone which, in most cases, involves the stapes bone (stirrup). Sound vibrations are thus impeded through the chain of hearing bones as the stapes becomes fixed by the overgrowth of bone. The result in such a case is a conductive hearing loss. Sometimes, however, the process may involve the inner ear also resulting in a nerve or mixed hearing loss. Otosclerosis is an hereditary disease and many individuals who have it are aware of relatives with similar hearing problems. This is not always so as the disease may skip generations and therefore a person with otosclerosis should not necessarily expect his children to be affected. Hearing loss from otosclerosis is rare in children and usually becomes evident between the ages of 20 to 50. It is twice as common in women as in men and frequently is noted to worsen following pregnancy. At any rate, it takes otosclerosis many years to cause a noticeable hearing loss and although it is usually progressive, causing a gradual worsening of the hearing, it rarely causes total deafness. In some cases, the otosclerosis spontaneously becomes inactive and the hearing loss does not increase. Associated with the hearing loss may be noises in the head known as tinnitus. These noises may be like ringing, roaring or hissing and are usually heard when the person is tense or in a quiet place.

Hearing Impairment from Otosclerosis Medical Treatment Surgical ... The Stapes Operation BACK TO EAR DISORDERS OTOSCLEROSIS Otosclerosis is a common cause of hearing impairment. (The word "otosclerosis" can be broken into its two roots: "oto" for ear, and "sclerosis" meaning hardening.) Approximately 5% of all people with hearing impairment have otosclerosis. The condition is hereditary. That is, members of a family pass the condition down to their children. Although otosclerosis is hereditary, the children of patients with otosclerosis will not necessarily develop the condition. Hearing Impairment from Otosclerosis Medical Treatment There is no local treatment to the ear itself or any medication that will improve hearing in persons with otosclerosis. In some cases, medication might prevent further nerve hearing loss. A medication known as Florical (8.3mg sodium fluoride and 364mg of calcium carbonate) is sometimes prescribed to prevent further nerve hearing loss. This medication slows down the abnormal bone growth and can eventually stop the growth of otosclerosis. The optimal dosage of Florical is 1 capsule two times daily with meals. Ideally, this medication should be taken for two years. After two years, the hearing level, the degree of tinnitus, and the severity of imbalance are reevaluated. If these conditions have stabilized, the Florical may be discontinued or the dosage reduced. Florical should be avoided during pregnancy.

OTOSCLEROSIS Your hearing impairment is caused by otosclerosis, a disease of the middle ear bones. 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, measles and influenza have no relationship to the development of otosclerosis. FUNCTION OF THE NORMAL EAR The ear is divided into three parts: the external ear, the middle ear and the inner ear. The external ear collects sound, the middle ear mechanism transforms the sound and the inner ear receives and transmits the sound. Sound vibrations enter the ear canal and cause the eardrum to vibrate. Movements of the eardrum are transmitted across the middle ear to the inner ear fluids by three small ear bones. These middle ear bones (hammer or malleus, anvil or incus and stirrup or stapes) act as a transformer changing sound vibrations in air into fluid waves in the inner ear. The fluid waves stimulate delicate nerve endings in the hearing canals. Electrical impulses are transmitted on the nerve to the brain where they are interpreted as understandable sound. 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.

Otosclerosis What Is Otosclerosis? How Do We Hear? How Does Otosclerosis Cause Hearing Impairment? What Causes Otosclerosis? ... Where Can I Get Additional Information? What Is Otosclerosis? 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? Image of the inner ear larger image 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 sensorineural hearing loss (damaged sensory cells and/or nerve fibers of the inner ear), as well as a conductive hearing loss. What Causes Otosclerosis?

Gentamicin Surgical Therapy ... Vestibular Neuronitis and Migrainous Vertigo What is Otosclerosis? Otosclerosis is a disease in which there is abnormal hardening of the bone of the ear. This hardening causes the third middle ear bone, known as the stapes, to become fixed. Fixation of the stapes prevents it from moving and thus, prevents the transmission of sound of the middle ear to the inner ear. What causes Otosclerosis? Otosclerosis is an inherited disorder and that many people with this disorder will report similar symptoms in their parents or siblings. Other patients report no family history of this disorder. This is not because their family members were not affected by otosclerosis, but rather because the hardening of the bone within the ear did not take place in the region of the stapes. How is otosclerosis diagnosed?

Disease Injury Nutrition Poison ... Ear anatomy Otosclerosis Definition: Otosclerosis is an abnormal bone growth in the middle ear that causes hearing loss Alternative Names: Otospongiosis Causes, incidence, and risk factors: 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, 15 to 30 years old. Risks include pregnancy (which may trigger onset) and a family history of hearing loss. Caucasians are more susceptible to otosclerosis than others. Symptoms: hearing loss slow, progressive hearing may be better in noisy environments than quiet areas. ringing in the ears (tinnitus) Signs and tests: An examination of the ears may rule out other causes of hearing loss An audiometry audiology may determine the extent of hearing loss.

what is an audiologist diagnostic services ... otosclerosis Otosclerosis (“oh-toe-sclare-o-sis”) is a condition that affects hearing as a result of hardening of a bone or bones in the middle ear. The hearing loss associated with this disease is called a conductive hearing loss because the extra bone growth around the middle ear bones prevents sound from being conducted into the inner ear in a normal way. Otosclerosis is inherited and tends to run in families although you may not know who in your family passed it on to you. About 80 percent of people with otosclerosis will have the disease in both ears. If you have otosclerosis, we estimate that there is less than a one in four chance of passing it on to your children. Sound vibrations that reach the eardrum are usually relayed to the inner ear by way of three small bones in the middle ear. These tiny bones, called the hammer (malleus), anvil (incus) and stirrup (stapes) act as a kind of transformer to change sound waves into liquid waves in the inner ear. The liquid waves activate delicate nerve endings in the inner ear. These nerve impulses are then carried along the hearing nerve to the brain. The stapes bone is the final link in the hearing chain of bones and is the bone most often affected by otosclerosis. When the stapes hardens a conductive hearing loss occurs. As the hardening continues over time your hearing worsens. When the hardening spreads to the inner ear a sensorineural hearing loss occurs. A sensorineural hearing loss is a nerve hearing loss that usually is permanent and can only be helped with a hearing aid.

I also knew I lost my balance easily, fell off ladders, and sometimes seemed to sway or stumble when I walked. I had unexplained dizzy spells. People said I didn't listen. But how could I listen, when I couldn't hear? They'd laugh at me when I mispronounced words and ridicule my incredibly poor spelling. How could I pronounce and spell words properly when I couldn't hear part of the sounds?

Otosclerosis is a condition of the middle ear which causes hearing loss that gets worse over time. Unlike hearing loss resulting from damage to the inner ear, the hearing loss from otosclerosis is often reversible. The name otosclerosis comes from the Greek words for "hard" ( scler-o ) "ear" ( oto ). This is because otosclerosis is a disorder which causes a hardening of the bones of the middle ear. To understand why otosclerosis causes hearing loss, it is important to understand how the ear works. The human ear is divided into three parts: the external, middle, and inner ear. The external ear consists of the part of the ear you can see (the auricle ) and the ear canal.
