The AOCMF Classification Group developed a hierarchical three-level craniomaxillofacial (CMF) classification system with increasing level of complexity and details. The basic level 1 system differentiates fracture location in the mandible (code 91), midface (code 92), skull base (code 93), and cranial vault (code 94); the levels 2 and 3 focus on defining fracture location and morphology within more detailed regions and subregions. Correct imaging acquisition, systematic analysis, and interpretation according to the anatomic and surgical relevant structures in the CMF regions are essential for an accurate, reproducible, and comprehensive diagnosis of CMF fractures using that system. Basic principles for radiographic diagnosis are based on conventional plain films, multidetector computed tomography, and magnetic resonance imaging. In this tutorial, the radiological issues according to each level of the classification are described.
AO颅颌面骨折分类小组开发了一种层次化的三级颅颌面（CMF）分类系统，其复杂性和细节程度逐级增加。基本的1级系统区分下颌骨（编码91）、面中部（编码92）、颅底（编码93）和颅顶（编码94）的骨折部位；2级和3级则专注于在更详细的区域和亚区域内定义骨折部位和形态。根据CMF区域的解剖和手术相关结构进行正确的影像采集、系统分析和解读，对于使用该系统准确、可重复且全面地诊断CMF骨折至关重要。放射诊断的基本原则基于传统平片、多排螺旋计算机断层扫描和磁共振成像。在本教程中，将描述根据分类的每个级别所涉及的放射学问题。
