Nose tip still purple two years after Open Rhinoplasty

The tip of my nose is noticeably purple, to the point I must recover it with makeup 2 or 3 times during he day so I don't look like Rudolph. My surgeon, Dr. Angelo Cuzalina, has seen me many times since the rhino where I have pointed out my concern. He just shakes it off without explanation as if it was nothing. I'm worried because a former patient of his has his nose completely disintegrate. On top of which I hate my new nose.
