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.

Otosclerosis is when abnormal bone remodeling occurs in your middle ear. Bone remodeling is a normal lifelong process in which existing bone tissue replaces itself with new bone tissue. When this process doesn’t go as expected, however, it can cause health problems. With otosclerosis, the tiny bones inside of your middle ear (the malleus, incus and stapes) become hardened and stop vibrating. As a result, sound doesn’t travel properly. Surgery is usually necessary to treat otosclerosis.Important ENT Termsluigi keeger
