[The value of 2- and 3-dimensional computed tomography in the diagnosis and classification of midfacial and orbital fractures].

The value of 2D- and 3D-computed assisted tomography in detecting and classifying midfacial fractures and craniofacial deformities acquired by gunshot injuries was assessed in 123 resp. 26 patients and compared with the postoperative results. In a comparative study 37 patients were prospectively examined by pluridirectional tomography. Examinations of a macerated skull were performed to optimize 3D investigation technique. High resolution CT proved to be the most reliable technique in detecting midfacial fractures and associated soft tissue injuries. 3D-imaging of bony surfaces allowed clear demonstration of fraction extent and fragment displacement without offering additional detail information. 3D-based computer-assisted manufacturing of individual models facilitated surgical planning of complex midfacial injuries.
