C and D: Six months postoperatively, circumferential graft absorption is present. E and F: Fifteen months postoperatively, further graft absorption is noted. G and H: At five years, the greatest part of the bone graft has been resorbed. A mesh of thin osseous septa is seen around the remaining bone graft. The lesion has not expanded since the first postoperative image.
