Could the bump on my bridge be diced cartilage or bone and what is the best approach to minimize it? 8 months post op (photos)

Hello and thank you for your question. Rasping alone will usually not permanently fix this. It can make it look better for 1 to 2 months and then it will usually get worse with worsening contour regularities due to the thin dorsal skin. What is usually a much better technique is rasping, followed by a fascial dorsal onlay graft. With good surgical technique, you could have an outstanding result. I recommend that you seek consultation with a qualified board-certified rhinoplasty surgeon who can evaluate you in person.

Best wishes and good luck.
