Unusual costochondral bone graft complication.

In hemifacial microsomia, patients with severely hypoplastic mandibles (Pruzansky type III) require replacement of the ramus and condyle unit. Common complications of this procedure include graft fracture and overgrowth of the graft. An uncommon case of osteolysis of the costochondral graft with osteitis of the middle cranial fossa is reported herein. To our knowledge, no such case has been reported in the literature previously. The aim of this report is to present the only known case and to discuss the contributing factors.
