Stapedectomy is a surgical procedure that involves removing the stapes bone from the middle ear and replacing it with a prosthesis. The stapes bone is the smallest bone in the human body and is located in the middle ear. It is part of the three bones that transmit sound waves from the eardrum to the inner ear.
The procedure is typically performed to treat a hearing loss condition called otosclerosis, which is the abnormal growth of bone in the middle ear. This growth can immobilize the stapes bone, preventing it from vibrating in response to sound waves and thus causing hearing loss.
Stapedectomy is usually performed under local or general anesthesia and involves making a small incision behind the ear to access the middle ear. The stapes bone is then carefully removed, and a prosthesis is placed in its position to help transmit sound waves to the inner ear.
The procedure has a high success rate and is considered safe and effective in restoring hearing in patients with otosclerosis. However, as with any surgical procedure, there are risks associated with stapedectomy, such as infection, dizziness, and ringing in the ear (tinnitus).
Therefore, it is important to discuss the benefits and risks of the procedure with an experienced ENT (ear, nose, and throat) specialist before deciding to undergo stapedectomy.
