常规头颅CT颅底薄层对眼眶内侧壁骨折的诊断价值

The Diagnotic Value of Routine Head CT Scan of Skull Base Thin of the Medial Orbital Wall Fracture

目的评价常规头颅CT颅底薄层扫描对眼眶内侧壁骨折的诊断价值。方法对63例头颅CT颅底薄层扫描拟诊眼眶内侧壁骨折者行眼眶CT扫描。结果 63例中60例在眼眶CT上确诊为眼眶内侧壁骨折,常规头颅CT加颅底薄层扫描显示的眼眶内侧壁骨折征象包括:眼眶内侧壁骨质连续性中断、内陷及粉碎性骨折,内直肌增粗、移位,眶内容物疝,筛窦积液,眶内积气等。结论头颅CT颅底薄层扫描可以作为眼眶内侧壁骨折诊断或筛查手段。

Objective Evaluation of routine head CT scan of the skull base thin medial orbital wall fracture diagnosis. Methods 63 cases with cranial CT scan of skull base diagnosed thin medial orbital wall fracture underwent orbital CT scanning. Results Of 63 cases in 60 cases diagnosed in the orbital CT on the medial orbital wall fracture,skull base plus conventional head CT scan shows thin medial orbital wall fracture signs include： continuous bone of medial orbital wall disruption,depression,and smash fracture,medial rectus thickening,displacement,herniation of orbital contents,ethmoid sinus effusion,gas and other orbital product. Conclusion Head CT scan of skull base can be used as thin medial orbital wall fracture diagnosis or screening tool.
