Tridimensionallocalization of bone and soft tissue injuries in complex facial trauma is fundamental for treatment. The face can be conceptualized as 3 groups of interconnected osseous struts that are oriented in the horizontal, sagittal and coronal planes. Each group of struts is closely related to specific soft tissue structures that are susceptible to injury. Any single CT section in the coronal plane or in the axial plane contains parts of one or more these struts. Facial CT in biplane were performed in 32 patients of facial trauma. The most common site of facial fractures is found in middle part of horizontal struts, geometrically in anteromedial portion of the inferior orbital fissure of the face. The most common soft tissue injury combined with facial fracture is hematoma and/or herniated orbital contents into the maxillary sinus. The serious combined 50ft tissue injuries were ocular rupture, retroorbital hematoma and optic nerve injury resulting blindness. CT was superior to conventional lineal tomography for evaluation of the extent of fracture, direction of displaced bone fragments, simultaneously associated brain and 50ft tissue injuries except thin linear fracture. So CT in biplane should be considered after screening simple X-ray study in complex facial trauma.
