Hello I had a nose job 15 years ago now columnella is symmetrical due to nasal tip changes made during surgery.. Can I get a long term filler to make my columnella more symmetrical? Can it be done safely without infection? What about renuva or can a small tissue graft be placed to fill in the side which is too high to be more symmetrical to the right ride without having to make other. Changes to the nose? If so how can the graft be made so it's not visible through he skin?
