Isolated zygomatic arch fractures are common fractures in maxillofacial trauma. These fractures can trigger a functional alteration in the mouth opening and closing. Until now, there is no published classification of an isolated zygomatic arch fracture that contains the presence or not of coronoid impingement. So we propose a new classification that is easy to handle and has the largest number of scenarios that can occur in this type of fracture. The isolated zygomatic arch fracture is classified as Type I: Nondisplaced fractures, Type II: Greenstick fracture with or without coronoid impingement, Type III: Single displaced fracture with or without coronoid impingement, Type IV: Multiple displaced fracture with or without coronoid impingement, Type V: Comminuted fracture with or without coronoid impingement. We consider it to be a comprehensive classification, with general concepts of bone fractures, that can be incorporated into professional daily practice.
孤立性颧骨骨折是颌面外伤中常见的骨折。这些骨折会导致口腔开口和闭合功能发生改变。到目前为止，还没有发表过一种包含喙突撞击与否的孤立性颧骨骨折分类。因此，我们提出了一种新的分类方法，这种分类方法易于操作，并且包含了这种类型骨折中最可能出现的各种情况。孤立性颧骨骨折分为以下五型：Ⅰ型：无移位骨折；Ⅱ型：伴有或不伴有喙突撞击的青枝骨折；Ⅲ型：伴有或不伴有喙突撞击的单处移位骨折；Ⅳ型：伴有或不伴有喙突撞击的多处移位骨折；Ⅴ型：伴有或不伴有喙突撞击的粉碎性骨折。我们认为这是一种全面的分类方法，包含了骨折的一般概念，可以纳入专业的日常实践中。
