stem cell tissue

It’s been a little bit since I posted anything but I had read something on here about this procedure called Vivaer , I just went to another ENT doctor today. That said that wouldn’t work for me. I have way too many. it taken out back in the 90s so it looks like there’s no help although I found some thing at the university in Houston Texas that they’re doing stem cell to replace lost tissue from the drs that took way too many out , has anybody heard about these stem cells that they use your own fatty tissue to replace in your nose?
