Lateral view of facial fractures: new observations

Traditional plain film evaluation of facial fractures includes a lateral view of the face. This projection is often not exploited to its full potential because the many overlapping shadows are perceived to detract from its usefulness. To assess the value of this view, the authors reviewed the later al facial films of 50 patients with a variety of fractures including 25 orbital blow-out fractures, 27 zygomaticomaxillary complex fractures, and 17 maxillary (including Le Fort) fractures. Three observations were encountered: orbital floor displacement in 60% of orbital fractures; malar strut displacement in 41% of zygomaticomaxillary complex fractures; and maxillary wall displacement in 76% of maxillary fractures. The presence of any of these structural displacements, either alone or in combination, provides further direct evidence of skeletal disruption and should serve to augment the findings observed on frontal views.
