目的:分析和评价螺旋CT对眼眶内侧壁爆裂性骨折的诊断价值。方法:回顾分析39例40眼眼眶内壁爆裂性骨折的资料,均行螺旋CT常规检查,同时进行多平面重建(PMR),并对CT征象进行分析。结果:眼眶壁骨折直接征象为眶壁骨质的连续性中断、粉碎、凹陷,多合并内直肌增粗、眶内积气、筛窦积气等间接征象。结论:螺旋CT能准确显示眼眶壁骨折的部位、程度和并发症,具有非常重要的临床意义。

AIM:To analyze and evaluate diagnosis significance of spiral CT for blowout fracture of medial orbital wall.·METHODS:Totally 39 patients 40 eyes with blowout fracture of medial orbital wall were analyzed retrospectively,and underwent the spiral CT examination and multi-planar reconstruction (PMR). The CT signs were analyzed.·RESULTS:The direct signs of orbital wall fracture was discontinuity of orbital wall,crushing,depression and most of which merged with some indirect signs such as the medial rectus thickening,orbital product gas,antrum ethmoidale gas and so on.·CONCLUSION:Spiral CT can accurately present the position,extent and complications of orbital wall fracture,and has the important clinical significance.
