眶周骨折伴复视的CT评价

CT evaluation of diplopia after the orbital fracture

目的 :探讨外伤性眶周骨折伴复视的CT诊断价值。方法 :回顾性对照分析 68例 ( 70只眼 )眶周骨折伴复视病例的CT图象和专科检查、临床资料 ,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检查诊断眶周骨折的正确率可达 10 0 %。 68例中 64例临床出现垂直复视 ,4例为水平复视。结论 :CT可以正确诊断眶周骨折部位并分型 ,帮助鉴别产生复视的原因 。

Objective: To evaluate the application of CT in the diagnosis of fracture position and the cause of diplopia after orbital trauma. Methods:The CT findings and the clinical informations of orbital fractures accompanying diplopias in 68 patients (70 orbits) were retrospectively analysed. Results: Orbital fractures in 70 orbits were diagnosed by CT. There were burst orbital floor fractures in 45 orbits ( among them orbital floor fracture combined with medial wall fracture in 15 orbits), non-burst obital floor fractures in 10, medial orbital fractures in 5, zygomatic-orbital fractures in 5, orbit roof fractures in 5. The accuracy of CT in diagnosing orbital fracture was 100 percent. In 68 cases, there were 64 patients with vertical diplopia and 4 with horizontal diplopia . Conclusion: CT can correctly locate the orbital fracture and diagnose the cause of diplopia.
