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.
传统的面部骨折X线平片评估包括面部侧位片。由于许多重叠阴影被认为会降低其有用性，所以该投照方式的潜力常常未得到充分发挥。为评估该视图的价值，作者回顾了50例患有各种骨折患者的面部侧位片，其中包括25例眼眶爆裂骨折、27例颧上颌复合体骨折和17例上颌骨（包括Le Fort）骨折。观察到三点：60%的眼眶骨折存在眶底移位；41%的颧上颌复合体骨折存在颧骨支柱移位；76%的上颌骨骨折存在上颌壁移位。这些结构移位中的任何一种，单独或合并出现，均为骨骼破坏提供了进一步的直接证据，并且应有助于补充在正位片上观察到的结果。
