摘要 目的研究常规X线、口腔曲面断层片、二维CT和三维CT在颌骨骨折诊断中的优缺点。方法对74例不同类型的上、下颌骨骨折的常规X线、曲面断层片、二维CT和三维CT的显示情况进行对照和分析。结果下颌骨易发生骨折,其中下颌骨体部骨折率最高,然后依次为髁状突、下颌角、升支;三维CT在颌骨骨折诊断的准确率最高,二维CT、口腔曲面断层片、常规X线次之(P<0.05);对下颌骨骨折线的显示准确率三维CT最高,口腔曲面断层片次之,但两者之间差异无统计学意义(P>0.05),而对上颌骨骨折线三维CT的准确率最高,二维CT次之,两者之间差异有统计学意义(P<0.05)。结论4种影像学检查各有优缺点,为提高骨折显示的准确率,4种方法结合使用是必要的。
