[Maxillofacial injury and x-ray computed tomography].
Facial injuries often occur as a result of cranio-encephalic trauma. They are preferentially studied by CT. In the emergency situation, CT is primarily useful to identify post-traumatic brain damage, which determines the vital prognosis. The study of the orbital apex and temporomandibular joint in the same session provides useful information about the functional prognosis. Further CT studies are required for a complete maxillofacial evaluation. They are usually performed 6 days after the trauma. Coronal and axial thin slices provide a definitive assessment of the bony structures involved. These two CT examinations warrant optimal preoperative planning.
