Clinical assessment of patients with facial injuries can be difficult, particularly if there is extensive soft tissue swelling. The maxillofacial surgeon frequently must rely on radiographic images to confirm and delineate the presence of fractures. In particular, the mid-third of the face is a notoriously difficult area in which to delineate fracture lines in the severely injured patient. In this study, three radiographic techniques were compared for the evaluation of patients with mid-facial fractures treated in a major trauma center: plain films; panoramic zonography; and computed axial tomography. The results indicate that quality plain films are frequently difficult to obtain in the severely injured patient. In selected cases, panoramic zonography and computed axial tomography are important complementary methods for accurate assessment of mid-third facial fractures.
对面部受伤患者进行临床评估可能会很困难，尤其是在存在广泛软组织肿胀的情况下。颌面外科医生常常必须依靠影像学图像来确认和描绘骨折的存在。特别是，面部中三分之一区域在严重受伤患者中是出了名的难以描绘骨折线的区域。在本研究中，比较了三种影像学技术，用于评估在一家大型创伤中心接受治疗的面中部骨折患者：平片；全景体层摄影术；以及计算机轴向断层扫描。结果表明，在严重受伤患者中常常难以获得高质量的平片。在某些选定的病例中，全景体层摄影术和计算机轴向断层扫描是准确评估面中部三分之一骨折的重要补充方法。
