What Is Stapedotomy Surgery?
Stapedotomy (also called stapedectomy) is a surgical procedure where the stapes bone in the middle ear is replaced with a prosthesis. This operation helps restore sound transmission to the inner ear and is used to treat hearing loss caused by otosclerosis—a condition where abnormal bone growth stiffens the stapes, limiting its movement.
