Can ear cartilage be inserted back into ear?

As part of a rhinoplasty procedure I had ear cartilage removed from the back of the ear for a graft. It has been over a year since surgery and the discomfort remains. Is this likely to be due to scarring? If so, can this be treated? Also, can cartilage - whether the original cartilage in my nose, rib cartilage, cadaveric cartilage or any other material be inserted back into the ear?
