目的 探讨眼眶骨折的螺旋CT(SCT)表现,评价其临床指导价值.方法 60例眼眶骨折行SCT容积扫描得到常规轴位像后,通过重建得到多平面(MPR)图像,根据图像分析并结合临床征象,其中54例保守治疗,6例手术治疗.结果 眼眶骨折的直接CT征象为眶壁骨质连续性中断、粉碎、凹陷及曲度失常;上颌窦腔出现"泪滴征"是诊断眼眶下壁骨折的特异性间接征象,眼外肌明显嵌顿及眼球内陷和牵拉试验阳性是手术治疗的指征.结论 SCT容积扫描多平面像能全面、准确地诊断眼眶骨折,对临床治疗方法的选择有重要价值.
目的 探討眼眶骨摺的螺鏇CT(SCT)錶現,評價其臨床指導價值.方法 60例眼眶骨摺行SCT容積掃描得到常規軸位像後,通過重建得到多平麵(MPR)圖像,根據圖像分析併結閤臨床徵象,其中54例保守治療,6例手術治療.結果 眼眶骨摺的直接CT徵象為眶壁骨質連續性中斷、粉碎、凹陷及麯度失常;上頜竇腔齣現"淚滴徵"是診斷眼眶下壁骨摺的特異性間接徵象,眼外肌明顯嵌頓及眼毬內陷和牽拉試驗暘性是手術治療的指徵.結論 SCT容積掃描多平麵像能全麵、準確地診斷眼眶骨摺,對臨床治療方法的選擇有重要價值.

Objective To discuss the diagnosis and clinical value of spiral CT(SCT) in orbital blowout fracture. Methods The SCT MPR findings in conjunction with transaxia images in 60 cases of orbital blowout fracture were retrospectively analyzed. According to the this analysis,54 patients were treated conservatively and only 6 were under the opereation. Results Interruption of bone continuity, fragments, depression and displacement of orbital bone wall ."Tear drop"sign in the maxillary or ethmoid sinus was a characteristic indirect sign of inferior or medial orbital wall fracture. Enophthalmia obviously compacting of extraocular muscler and distraction test male were operation signs. Conclusion Orbital blowout fracture can be diagnosed by SCT volume scanning findings of the MPR comprehensively and accurately, that is very important in choosing the treatment methods for orbital blowout fracture.
