diagram of ear showing Otosclerosis

Otosclerosis is a condition involving fixation of one of the little bones in the middle ear. The sound waves are not transmitted through the fixed bones and produce a hearing loss. The disease usually starts in early adulthood and progresses over a period of years. The disease tends to run in families.  Treatment involves removing the little bone that is fixed and replacing it with a wire prosthesis. The operation, called a stapedectomy, was first done in the late 1950’s and has been very successful in correcting this particular type of hearing loss. Many different types of prosthesis are now available.
