眼眶骨折伴复视的CT评价

CT evaluation of diplopia after the orbital fractures

目的 探讨外伤性眼眶骨折件复视的CT诊断价值。方法 回顾性对照分析68例(70只眼)眼眶骨折伴复视病例的CT图像和专科检查资料,进行定位诊断和骨折分型。结果 70只眼中眶底爆裂性骨折45只眼(其中15只眼合并眶内侧壁骨折),眶底非爆裂性骨折10只眼,鼻眶骨折5只眼,颧骨骨折5只眼,眶上部骨折5只眼。CT(横轴位结合冠状位)检查诊断眼眶骨折的准确率可达100％。68例中64例临床出现垂直复视,3例为水平复视。结论 CT可以准确诊断眼眶骨折部位并分型,帮助鉴别产生复视的原因,为临床提供科学依据。

Purpose To evaluate the fractural position and the cause of diplopia after orbital trauma. Methods The CT findings and the clinical informations of 68 patients (70 orbits) of orbital fractures accompanying diplopias were retrospectively analysed. Results In 70 orbits of orbital fractures diagnosed by CT,There were floor orbital fractures 40 orbits (both the orbital medical and floor fractures 15 orbits), medical orbital fractures 5 orbits, zygomatic - orbital fractures 5 orbits, orbit roof fractures 5 orbits. The accuracy of CT(axial and coronal) in diagnosing orbital fracture was 100 percent. In 68 pationts of diplopias, There were vertical diplopias in 64 patients and horizontal diplopias in 4 patients. Conclusion CT can correctly locate the orbital fracture and diagnose the cause of diplopia.
