[Trauma of the facial bones and skull].

Facial trauma is frequent and mainly caused by motor vehicle accidents. Due to this main etiologic factor, trauma to the facial skeleton is often associated with serious injuries, commonly involving the brain, chest or abdomen. As a consequence, the initial clinical management of these patients includes control of hemorrhage and immediate assessment of life-threatening injuries, including the maintenance of the airways. Patients presenting with facial trauma are initially evaluated with a systematic clinical examination because many fractures can be accurately diagnosed by inspection and palpation alone. In these cases plain film radiographs serve only for confirmation and documentation of the diagnosis. In many other cases accompanying and extensive soft tissue swelling may clinically obscure fractures. A complete and accurate evaluation of these patients requires additional radiological imaging methods. A series of plain films may be generally sufficient but in most of the cases they can be regarded as initial screening methods for more thorough diagnosis with computed tomography (CT). In trauma patients CT is the imaging method of choice because it shows more fracture lines and displaced fragments than any other imaging modality. CT delineates soft tissue and bony structures and can localize and even characterize foreign bodies. A complete and accurate characterization of the fracture type and potentially associated complications in mandatory for the appropriate treatment and can only be achieved by careful radiological (CT) evaluation.
