Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis. If the stapes footplate is fixed in position, rather than being normally mobile, the result is a conductive hearing loss. There are two major causes of stapes fixation.
The stapes is the third bone of the three ossicles in the middle ear and the smallest in the human body. It measures roughly 2 to 3 mm , greater along the head-base span. [ 1 ] It rests on the oval window , to which it is connected by an annular ligament and articulates with the incus , or anvil through the incudostapedial joint . [ 2 ]

Indications for use of an ossicular replacement prosthesis include: [1] Chronic middle ear disease; Otosclerosis; Congenital fixation of the stapes; Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery; Surgically correctable injury to the middle ear from trauma
