Otosclerosis is an abnormal bone growth in the middle ear that causes hearing losshearing loss.<\/p>\n
The 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 vibrating in response to sound waves \u2014 which must happen in order for you to hear. This lack of vibration leads to hearing loss that continues to get worse with time.
\nOtosclerosis 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.
\nOtosclerosis can lead to not only conductive hearing loss, but to nerve loss as well.
\nRisks include pregnancy (which may trigger onset) and a family history of hearing loss. Caucasians are more susceptible than others to otosclerosis.<\/p>\n

A hearing test (audiometryaudiometry\/audiologyaudiology) may determine the extent of hearing loss. Temporal-bone CT may be used to distinguish otosclerosis from other causes of hearing loss.<\/p>\n
Otosclerosis may slowly get worse. The condition may not require treatment until you having severe hearing problems.
\nMedications such as oral fluoride, calcium, or vitamin Dvitamin D may help to control the hearing loss, but the benefits have not yet been proved.
\nA 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.
\nSurgery to remove part of the ear (stapes) and replace it with a prosthesisprosthesis 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.<\/p>\n
Otosclerosis gets worse without treatment, but surgery may restore at least partial hearing. Most complications of surgery get better by themselves within a few weeks.
\nTo reduce the risk of complications after surgery:
\n\u2022 Do NOT blow your nose for 1 week after surgery.
\n\u2022 Avoid people with respiratoryrespiratory or other infections.
\n\u2022 Avoid bending, lifting, or straining, which may cause dizziness.dizziness.
\n\u2022 Avoid loud noises or sudden pressure changes such as scuba diving, flying, or driving in the mountains until healed.
\nIf surgery is unsuccessful, total hearing loss may occur. Treatment then involves developing skills to cope with deafnessdeafness, including use of hearing aids and visual cues.<\/p>\n

\nWhen to Contact a Medical Professional
\nCall your health care provider if hearing loss occurs.
\nCall your health care provider if fever, ear pain, dizziness, or other symptoms develop after surgery.<\/p>\n
Another choice for hearing loss in Otosclerosis is hearing aids. If you have otosclerosis in one or both of your ears, your doctor may suggest you a hearing aid.<\/p>\n
