Technological advances in computerized tomography (CT) have reduced data acquisition and reconstruction times so that three-dimensional (3D) CT images of maxillofacial injuries may be economically and quickly generated. 3DCT was judged superior to multiplanar two-dimensional CT in demonstrating the spatial relationships of fracture fragments in complex mandibular and midfacial trauma. Although 3DCT failed to demonstrate soft-tissue injuries well, the surgeon's improved appreciation of the disrupted bony architecture facilitated preoperative planning. 3DCT facilitates the evaluation of complex mandibular and midfacial fractures.
