Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.
