目的:评价颧蝶缝在颧骨骨折复位中的意义,寻找颧蝶缝的暴露方法。方法:以尸头为研究对象,人为造成颧骨骨折后,先后采用常规复位方法及以颧蝶缝为复位标准方法进行复位固定,比较复位效果。分别采用口内及口外2种方法暴露颧蝶缝。结果:暴露颧蝶缝并直视下复位颧蝶缝再复位其他可见骨折线,能使颧骨骨折达到解剖复位,口内法仅能触摸到不能直视该缝,口外法可直视该缝全部。结论:颧蝶缝可作为颧骨复位的可靠标准,口外法为暴露颧蝶缝的可靠方法。
OBJECTIVE: To evaluate the significance of zygomatic butterfly's seams in the reduction of zygomatic fractures and to find the way to expose them. Methods: The cadaveric head was taken as the research object. After the fractures of zygomaticus were caused by human being, reduction and fixation were performed by the conventional reduction method and the standard method of zygomatic butterfly suture as the reduction. The reduction effect was compared. Two methods of mouth and mouth were used to expose the zygomatic butt joint. Results: Exposed zygomatic butterfly's seams and reset the zygomatic seams under direct vision and then reset the other visible fracture line, can make the zygomatic fracture to anatomical reduction, the intraoral method can only touch can not look directly at the seam, . Conclusion: Zygomatic buttress can be used as a reliable standard for the reduction of zygoma. Occular method is a reliable method for exposing zygomatic buttress.
