摘要
目的:研究常规X线、二维CT和三维CT在颌骨骨折诊断中的优缺点。方法:对125例不同类型的上、下颌骨骨折的常规X线、二维CT和三维CT的显示情况,以及手术结果进行对照和分析。结果:对于下颌骨体部、角部和升支骨折,3种影像学都能很好的显示,对于髁状突和喙突骨折,三维CT检查优于常规X线和二维CT;常规X线显示上颌骨骨折较差,而二维CT和三维CT显示的准确性比较接近。三维CT可以直观和立体的显示颌骨骨折线。结论:3种影像学检查各有优缺点,为提高骨折显示的准确率,3种方法结合使用是必要的。
Objective: To evaluate the advantage and disadvantage of conventional X -ray plain film ,2D -CT and 3D -CT in the diagnosis of jaws fractures. Methods: 125 cases of jaws fractures were examed by the conventional X - ray plain film, 2D - CT and 3D - CT before operation. The results of three methods were compared with each other and with the operation findings. Results: Fractures in body, angle and ascending branch of mandible could be showed fine by all these imaging methods. 3D - CT was better than 2D - CT and conventional X - ray plain film in the diagnosis of fractures in condyle and coronoid process. Conventional X - ray plain film was poor in the diagnosis of the maxillary fractures. 2D - CT and 3D - CT was similar in the diagnosis of the maxillary fractures. 3D - CT showed the jaws fractures directly and stereoscopicly. Conclusion:Each of these three methods has its advantage and disadvantage in showing jaws fractures. In order to increase the accurate rate of diagnosis, a combination of three methods is necessary.
