Otosclerosis is a common cause of deafness with an intact ear drum. When sound waves fall upon the ear drum, it vibrates. These vibrations are transmitted by a chain of 3 mobile bones called ossicles in the middle ear from the drum to the inner ear.

Immobility of stapes bone due to microscopic abnormal growth of bone in the walls of the inner ear.

This abnormal growth causes the stapes bone to become immobile or fixed. Normally the stapes vibrates freely to allow the transmission of sound to the inner ear, but when it cannot move, it prevents sound waves from reaching the inner ear fluids, and hearing is impaired. Otosclerosis affects only the ears and involves both ears usually one after another.

It occurs in both men and women but women are usually affected slightly more frequently. Otosclerosis affects people in the prime of life that is around middle age. Pregnancy is known to aggravate the situation.
