Maybe. It is for noise damage, but tinnitus is a brain problem so it may not fix tinnitus. That's the most straightforward answer anyone here can give.
although I would like to believe in hair cells restoration, I am just becoming more and more pessimistic. I don't think this is possible. Even if they manage to restore hair cells, they won't be the same as the first ones. Sometimes, technology (hearing aids) is our only option.
it is really hard to predict. Who knows what is really going on. I have been reading so much experiments that were done in 2009 on Pubmed (I think) . And all of these experiments are successful on mice and hamsters. Then I ask myself why these things are not on the market already or promoted among doctors?
Yeah you know that's a damn good question. It's because of testing. From what I heard a good metric with experimental medicine is that it takes 20 years to go from print-to-practice, meaning if you hear about it today, it will be in hospitals in 20 years assuming it works.
