Back in 2011 I had a Stapedotomy not a Stapedectomy ( a stapedectomy typically removes the entire stapes footplate and has it replaced with a micro prosthesis. During a stapedotomy, a prosthesis is positioned within the precisely-made and measured hole that is created in the footplate of the stapes bone.). I just needed it in one ear and my hearing improved immediately and I had no problems.
I have read that the issue is finding an experienced doctor in this procedure. Originally there were a lot of people needing this procedure but with measles vaccine (measles thought to be one of the causes), there are now far fewer cases.
