What is a stapedectomy?

Stapedectomy is an ear operation to treat hearing impairment due to otosclerosis. 

What’s involved in the stapedectomy procedure?

Under or a general or local anaesthetic the tiny stapes bone is partially removed and a 0.8mm hole drilled through the remaining bit to accommodate an artificial replacement bone. This allows the ear to function normally and most often patients can do away with the need for a hearing aid.

What are the risks?

Although the operation gives more natural hearing than a hearing aid because there is no distortion or feedback, it is associated with some risks. There is a small chance of loss of hearing, dizziness and vary rarely tinnitus after the procedure. As one of the nerves has to be moved aside during the operation to allow access to the stapes bone, some patients notice an altered sense of taste, which usually resolves within six months.

What are the benefits of a stapedectomy? 

The operation has a greatly reduced chance of hearing loss when compared to stapedectomy in which the stapes bone is completely removed and is now considered the standard operative treatment.
