Stapes prosthesis (plural: stapes prostheses) are used in the stapedectomy surgery procedure which aims to improve conductive hearing loss due to oval window closure secondary to otosclerosis or post inflammatory conditions. The procedure is also performed to correct congenital abnormalities or discontinuity or fracture resulting from prior base of skull trauma.
It is important to remember that the stapes has a base which seals the oval window and conducts vibrations to the cochlea.
