In 1 week two patients with depressed fractures of the malar/orbital/zygomatic complex presented with roentgen evidence of fractures of the underlying coronoid process caused by the transmitted impact of the malar/orbital/zygomatic fragment without direct injury to the mandible. No similar cases had been seen in the previous 12 years, and reports found in the literature stated that this type of fracture occurs in only about 2% of all mandible fractures. Conservative treatment is recommended unless there is obvious displacement.
在1周内，两名颧骨/眼眶/颧复合体凹陷性骨折患者的X线检查显示，冠状突骨折是由颧骨/眼眶/颧骨碎片的传导性撞击所致，而下颌骨并无直接损伤。在过去12年中未见过类似病例，文献报道显示，这种骨折仅占所有下颌骨骨折的约2%。除非有明显移位，建议采取保守治疗。
