We report a case of mandibular fracture concomitant with lateral-superior displacement of both mandibular condyles. The patient was 69-year-old man. While operating a crane, a hanging iron pillar crashed into and injured his face at a construction site. Computed tomography showed a complex midline fracture of the mandible and lateral-superior displacement of both condylar heads. We were able to reposition both condyles into a normal position at an early stage. After 6 months' follow-up, the temporomandibular joint function was normal.
