Otoplasty with asymmetric results - Options? (photo)

A year ago I had an otoplasty, where cartilage was removed from the concha and some stitches were placed to make the ear move back. I always had my right ear more prominent than my left. A year after the surgery, I am still unhappy with the result. My right ear is still larger, not to mention that both have taken on a very curved shape. What could be done in my case if I don't want my ears to be closer to my skull than they already are?
