Hi, your question is a good one. This is actually somewhat common when cartilage grafts are placed on the dorsum of the nose especially if it is not wrapped or you have thinner skin. There are three things that can be done. First, sometimes the cartilage tends to resorb with time and is less apparent. This may take at least a year. Second, sometimes we can use a little needle to gently take it down even in the office. Finally, you could always go back in a more formal manner to remove that little culprit area of cartilage do a simple single incision inside the nose. I would caution to make sure that indeed it is cartilage and not just scar under the soft tissue.
