Hi Ned,
I find those percents a bit strange.... I have been told and have read that hearing pretty much stays the same with fsr i.e. at the level you went in with, plus a bit more loss maybe ... sometimes it stays at the same level even after fsr, and i have read about an exceptional few that improved a slight bit..... Have not ever heard about losing 50 % more than what one went into treatment with , after fsr?
About gentamycin?
Have you done a basic google search about gentamycin? even gentamycin drops for let's say a minor ear infection? well when the topic of otoxicity comes up, gentamycin is one of the drugs that can cause hearing loss by unknowing docs who prescribe it for minor ailments..........
About injections to destroy all of balance nerve in inner ear..... that is done as i uinderstand in order to knock out all vestibular balance in an ear...if it is done in both ears you end up in a wheelchair as you end up with no balance.....
In any case, that kind of treatment cannot be undone, so i would get some other opinions about why this is being suggested to you for even one ear.....
Tread carefully....
Sincerely,
Windsong
