Multidetector and three-dimensional CT evaluation of the patient with maxillofacial injury.

Interpretation of images associated with the traumatically injured face is challenging. The complexity of facial anatomy, coupled with the superimposition of numerous bony structures on plain radiographs, poses specific obstacles to accurate interpretation of facial injury. Although plain radiographs can be helpful in cases of isolated injuries, CT is the most useful modality for evaluating facial injury. This article reviews facial anatomy as it pertains to traumatic injury, emphasizes the clinical findings associated with various types of facial injury, and simplifies the diagnosis of facial injury on CT.
