This fixation stops some of the sound vibrations from reaching the inner ear fluids, causing therefore hearing loss. Stapedectomy Stapedectomy is an operation to remove the fixed stapes and to replace it with a prosthesis. This allows sound vibrations to be transmitted properly to the inner ear fluids for hearing. Causes of Otosclerosis Otosclerosis is not a cancerous growth or a tumor, but, rather, a somewhat self-limited growth of bone in such an area as to cause difficulty in hearing. It only occurs in the ear.
Otosclerosis is hereditary and is often seen in more than one member in a family.
Its hereditary nature, however, is somewhat irregular. It is not unusual to see otosclerosis only in one member of a family. Natural Course of Otosclerosis Otosclerosis may affect one or both ears of an individual and gradually causes progressive hearing loss as the bony growth gets larger. The speed at which the otosclerotic bone develops in an individual one. Though it usually takes many years for a significant hearing loss to result from otosclerosis, it may develop to a point and completely stop.
