眼眶内侧壁-纸样板骨折的CT诊断

CT diagnosis of laminapapyracea fracture

目的探讨眼眶内侧壁纸样板骨折的CT表现。方法对56例筛骨纸样板骨折病例CT轴位和冠状位薄层扫描进行回顾性分析。结果显示骨折线15例,纸样板断裂、内陷41例,同时合并内直肌肿胀,眶内及眼睑积气,内直肌内侧脂肪间隙变窄等间接征象。结论CT不仅发现纸样板骨折的类型,还可显示内陷的程度,是目前诊断眼眶内侧壁纸样板骨折最有效的办法。

Objective To research CT findings of laminapapyracea fracture. Methods 56 cases of axial and coronal thin slice CT scans with laminaprpyracea fracture were analyzed retrospectively. Results Fracture lines had been found in 15 cases. 41 cases had signs of discontious or concave of laminaprpyracea. Other findings included intraoeular muscles swelling, intraorbital air accumulatiaon. Conclusion CT scan can not only discover the fracture , but also can detect the degree of excvation of laminapapyracea. It is an effectual method to diagnose the fracture of laminapapyracea.
