The purpose of this article is to present a concept which facilitates the plain film identification of mid-face fractures. The concept evolves from a logical classification of mid-face fractures based upon the region(s) of involvement (orbit, zygoma, maxilla), the extent of the fractures (unilateral or bilateral) and the characteristic distribution of the fracture lines. Recognition of these fractures depends upon an awareness of the fact that the radiographic signs of mid-face fractures differ in certain respects from those involving other skeletal parts. In addition to skeletal disruption, the radiographic signs of mid-face fractures include soft tissue abnormalities which may be localized or diffuse, and which may be either extrinsic or intrinsic to the facial skeleton, alterations of normal skeletal contour, the "bright white line" of displaced fragments, and the subcutaneous emphysema which may also be localized or diffuse. The application of this concept to the roentgen diagnosis of mid-face fractures will be described and illustrated.
本文的目的是提出一种有助于通过平片识别面中部骨折的概念。该概念源自基于受累区域（眼眶、颧骨、上颌骨）、骨折范围（单侧或双侧）以及骨折线特征分布对面中部骨折进行的逻辑分类。认识这些骨折取决于认识到这样一个事实，即面中部骨折的影像学征象在某些方面不同于涉及其他骨骼部位的骨折征象。除了骨骼连续性中断外，面中部骨折的影像学征象还包括软组织异常，这些异常可能是局限性的或弥漫性的，可能是面部骨骼外部的或内部的，正常骨骼轮廓的改变，移位骨折碎片的“亮白线”，以及同样可能是局限性的或弥漫性的皮下气肿。将描述并举例说明这一概念在面中部骨折X线诊断中的应用。
