How to revise Blanch spot with bony lump on nose tip that appeared 8 months after nasal cartilage implant on the tip?

I had hump removal, dorsum narrowed (to prevent open rooftop), deviated nose straighten and a Nasal cartilage grafted on nose Tip. Prob: Blanch spot with hard bony bump on nose tip appeared since 2 mths ago. I believe it's a protuded grafted-cartilage sticking out underneath my Thin Skin (Shrink wrapping?). 1. Is it possible to fix this blanch spot without the need of fascia implant? 2. How to smooth this protruded cartilage without open rhino? Any suggestion will be appreciated. Thank you.
