OtosclerosisOtosclerosis is an abnormal bone growth in the middle ear that causes hearing loss. CausesThe cause of otosclerosis is unknown, but there appears to be a hereditary component, meaning it can be passed down through families. In this condition, an abnormal sponge-like bone grows in the middle ear. This growth prevents the ear from Otosclerosis is the most frequent cause of middle ear hearing loss in young adults. It affects about 10% of the U.S. population. It is a disorder that gets worse slowly, usually beginning in early to mid- adulthood. It is more common in women than in men. Otosclerosis usually affects both ears. Otosclerosis can lead to not only conductive hearing loss, but to nerve loss as well. Risks include pregnancy (which may trigger onset) and a family history of hearing loss. Caucasians are more susceptible than others to otosclerosis. Symptoms
A hearing test (audiometry /audiology) may determine the extent of hearing loss. Temporal-bone CT may be used to distinguish otosclerosis from other causes of hearing loss. Treatment Medications such as oral fluoride, calcium, or vitamin D may help to control the hearing loss, but the benefits have not yet been proved. A hearing aid may be used to treat the hearing loss. This will not cure or prevent hearing loss from getting worse, but may help relieve some of the symptoms. Surgery to remove part of the ear (stapes) and replace it with a prosthesis can cure the condition. A total replacement is called a stapedectomy. Sometimes a laser is used to make a hole in the stapes to allow placement of the prosthetic device. This is called a stapedotomy. >Back to Hearing & Balance

vibrating in response to sound waves -- which must happen in order for you to hear. This lack of vibration leads to hearing loss that continues to get worse with time.
Otosclerosis may slowly get worse. The condition may not require treatment until you having severe hearing problems.
