Stapedectomy involves removing bones from which part of the ear?

• A. Bones from the inner ear are removed and replaced with artificial ones
• B. Removal of outer ear bones
• C. Replacement of auditory nerve
• D. Removal of middle ear air cells

Answer: (A)

Stapedectomy targets the middle ear’s small bones called the auditory ossicles. In otosclerosis, the stapes (one of these bones) becomes fixed and can’t move, so vibrations from the eardrum don’t effectively reach the inner ear. The procedure removes the immobilized stapes and plugs in a prosthetic device that transmits vibrations directly to the oval window, restoring sound transmission into the fluid-filled inner ear. It does not involve removing inner-ear bones, outer-ear bones, replacing the auditory nerve, or removing middle ear air cells—those are not part of this surgery.
