眶内隐匿性骨折的CT诊断

CT Diagnosis of Occult Fracture in Orbit

目的探讨ＣＴ检查对眶内隐匿性骨折的诊断价值。方法对２３例患者的临床及ＣＴ影像进行回顾性分析。所有病人均摄眼眶Ｘ线片和眼眶ＣＴ横断扫描，其中９例加扫眼眶冠状位。结果２３例中，眶内壁骨折１２例，底壁骨折９例，顶壁骨折２例，８例无直接骨折征像（约占３４８％）。结论ＣＴ检查对眶内隐匿性骨折的诊断具有特异性。对有外伤史，临床怀疑有骨折。

Purpose To evaluate the role of CT in the diagnosis of occult fracture in orbit.Methods The clinical and CT findings of 23 patients with occult fracture in orbit were analysed retrospectively.23 convertional X ray films and CT images (with 23 axial CT scans and coronal CT scans) of the same orbits were performed. Results Of the 23 cases with occult fracure in orbit, 12 in the medial orbital wall, 9 in the orbital floor, 2 in the orbital top and 8 cases with negatively direct signs of orbital fracture (34.8%) were diagnosed by CT. Conclusion CT is of specificity to diagnosis of occuit fracture in orbit, once traumati history of orbit and clinically suspected frcture are found, CT scanning is recommended. [
