Hi. I've already had 3 open rhinoplasties and one closed revision. I've already had rib graft revision and the whole thing rebuilt. I've already had perichondrium and nano fat injected during the revision. I have been told I have extremely thin skin and also any more open revisions could compromise blood flow. I want more volume overall and I really want to fill in this dent. I don't want to do HA filler because I've seen Toriumi post that it's too risky. Is fat injection in the nose safer?
