Otosclerosis involves the formation of new bone that affects two structures within the ear, known as the cochlea and labyrinth. The cochlea is a cone-shaped tube involved in hearing, and the labyrinth is key to a person's sense of balance.
Otosclerosis is a form of bone overgrowth within the middle ear that causes progressive hearing loss.
The sense of balance may also be impaired.
The cause is unknown, but risk factors include family history, gender and pregnancy.
