What procedure involves removing and replacing the stapes?

The procedure that involves removing and replacing the stapes is known as stapedectomy. This surgical operation is performed to improve hearing in patients who have conductive hearing loss caused by otosclerosis, a condition where the stapes becomes fixed and unable to vibrate in response to sound. During a stapedectomy, the immobilized stapes bone is removed, and typically a prosthesis is inserted to take its place, allowing sound waves to be transmitted to the inner ear more effectively.

This procedure is significant because it directly addresses the mechanical issues in the middle ear that hinder sound transmission. Understanding this is crucial for professionals in audiology and hearing aid dispensing as it provides insight into some causes of hearing loss and the various surgical options available to patients.
