Otosclerosis - Stapes Surgery. Otosclerosis is a disease of bone affecting the ear. Normally, sound, a vibration of air molecules, is transmitted to the tympanic membrane, or eardrum. The drum vibrates as do the three bones of hearing, the malleus, incus and stapes. These three bones are suspended in the middle ear and are connected like a chain to the vibrating tympanic membrane. At the other end of the chain, the vibrations are transmitted to the inner ear by the last vibrating bone, the stapes. The inner ear or cochlea has nerve endings that transmit the sound to the brain.
