Otosclerosis

Otosclerosis is a progressive, familial disease that effects the bony otic capsule. Lesions involving the footplate of the stapes result in increased impedance to the passage of sound through the ossicular chain, causing conductive deafness. The condition may be treated either through the use of a hearing aid or surgical replacement of the stapes with a prosthesis (stapedectomy). When otosclerotic lesions impinge on the cochlea (cochlear otosclerosis), permanent sensory deafness occurs.
