Infection and exposed cartilage in the nose after revision rhinoplasty -- will this heal on it's ow?

I am two weeks post op from a revision rhinoplasty and have what seems like exposed cartilage in my nose. My septum was deviated and a cartilage graft added for tip support. I sent pictures to my doctors office and they haven't gotten back to me yet. Will this heal on its own? What are the implications of exposed cartilage? I am concerned about this leading to infection, scar tissue or other complications.
