Sound causes vibrations of the stapes bone. The vibrations pass into the fluid of the inner ear which allow you to hear. If the stapes bone cannot vibrate hearing will be decreased or lost.
Otosclerosis is a common reason for a stapedectomy. Otosclerosis is a growth of bone around the stapes that prevents the vibration of the stapes bone and leads to hearing loss. Surgery is required to improve hearing. A stapedectomy removes the damaged stapes and replaces it with an artificial one.
The surgery may also be done to correct a stapes that is fractured or abnormally shaped.

Special tools are used through the ear canal to access and view the middle ear. The eardrum will be gently lifted to allow access to the stapes bone. The stapes bone will be removed. Sometimes a laser is used to destroy parts of the bone and the remaining pieces are removed.
An artificial stapes replacement will be put in place. Once the new device is secure, the eardrum will be put back into place. A cotton or ointment plug may be placed in your ear canal. This packing will help keep the eardrum in place and protect the new stapes bone until it can set.
