First, I've just recently stumbled into this forum while looking into hearing aids and found the information and help to be fantastic!
I’ve had otosclerosis since I can remember and had a stapedectomy in my left ear in 1978. Prior to that I wore an aid in my right ear. That gave me the ability ‘get along’ for the next 8 years without any aid. I went back to using an aid in my right ear until 1988 when I had a stapedectomy in the right ear and have been able to again ‘get along’ without any aid until recently. I’m in a 45 day trial right now.
I see my ENT and have tests on a regular basis. The functioning parts put in with the stapedectomies are still functioning after all these years – the middle ears are not my problem. Ten years ago he put me on sodium fluoride hoping that it would prevent the progress to the inner ears. I don’t think the fluoride helped me but I’ve heard that others have benefited. My overall condition has changed very little in the past four years – maybe my age?
So, zafdor, according to the tests that I continue to have, my ongoing loss has been sensorineural.
This is just my experience – no advice for those deciding whether or not to have a stapedectomy is intended.
