Otosclerosis is an abnormal, microscopic growth of bone in the walls of the inner ear, which causes the stapes bone (the smallest bone in the body) to become frozen in place or "fixed." Normally, the stapes vibrates freely to allow the transmission of sound into the inner ear. When it becomes fixed to the surrounding bone, hearing becomes impaired.
- Hearing loss
- Dizziness/balance problems
- Ringing in the ears (tinnitus)
Diagnosis and Treatment
To diagnosis otosclerosis, an examination by an otolaryngologist is needed to rule out other diseases or health problems that may cause similar symptoms. An audiologist, who will test your hearing and balance functions, will then see you.
Although many patients can wear a hearing aid successfully, natural hearing is often preferred. Surgery has been found to be the most effective method of restoring natural hearing for patients diagnosed with otosclerosis.

Did you know?
Otosclerosis is among the most common causes of hearing loss in the general population.
A research team at Mass Eye and Ear was the first to discover an association between the measles virus and otosclerosis, which is considered to be one of the most significant contributions in the area of otosclerosis research in the last 50 years.
