What is otosclerosis?

Otosclerosis is a disease of the temporal bone.(bone surrounding the ear)Otosclerosis affects the ears only and not other parts of the body. It can cause hearing loss when hard bone forms around the stapes, reducing the vibration of stapes thereby decreasing transmission of sound to the inner ear. This is called conductive hearing loss. As the disease progresses, otosclerosis can interfere with the inner ear nerve cells causing sensorineural hearing loss.
