I have never known anyone who had tophi removed surgically, although I DID remove a small bean sized tophus from my own thumb with “self-surgery.” It did not grow back.
But don't do what I did, have a surgeon do it so that you don't infect anything. Make sure you go to someone with a track record…our hands are too valuable to f%$k with.
Here's my take on it: With a high uric acid your body will wall off urate into a tophus. But the “walliing off” means the body cannot see it, reduce it, etc. IF sometime later, one has controlled his serum uric acid, I see no reason why a removed tophus should grow back because there is no excess uric acid to grow it.
I have a lentil sized tophus on my little finger which is unnoticeable unless I point it out…I've decided to let it be.
My thumb over the years caused the occasional dull ache, nothing more. Little finger bugger, nothing at all.
