Otosclerosis causes ossification (bone formation), which has an adverse effect on the mobility of the stapes. The result is a slowly developing loss of conductive hearing. This disorder is commonly accompanied by a ringing in the ears (tinnitus).
Unfortunately, it is not possible to treat otosclerosis by medication currently. In certain cases, surgery is able to reduce hearing loss. However, in conductive hearing loss caused by otosclerosis, hearing can be greatly improved by hearing aids.
