Is it safe to shave nose to make it skinnier after osteotomies?

My previous surgery was a fail and now i have a huge shapeless nasal bridge and a pointy tip. I had a collapse from my first surgery on one side so the new dr did osteotomies and put cartilage on the collapsed side. The thing is now it looks like a balloon. Can i get the bones and cartilage shaved a bit with revision or will it collapse again?
