摘要
目的:探讨多层螺旋CT对眼眶内侧壁骨折的诊断价值。方法:77例眼眶内侧壁骨折全部行多层螺旋CT容积扫描及MPR、3D成像,综合分析眶内壁骨折的类型及CT征象。结果:爆裂骨折占80.5%,直接骨折占15.6%,复合骨折占3.9%。骨折直接征象是眶壁凹陷,骨质断裂、移位,骨质粉碎,眶壁曲度异常改变。骨折间接征象是内直肌肿胀、模糊和/或移位,筛窦积液,眶内容物疝,眶内积气,眶内出血,视神经肿胀和/或移位,眼球内陷,眼球突出,眼睑及眶周软组织肿胀、积气等。结论:多层螺旋CT扫描及MPR、3D成像对眼眶内侧壁骨折具有重要诊断价值。
Objective： The diagnosis value of spiral CT for orbital wall fracture.Method： Medial orbital wall fracture in 77 cases,All were detected by spiral CT,MPR,3D imaging,and then comprehensive analysed the orbital wall fracture type and CT signs.Result： Burst fracture of 80.5%,15.6% of direct fracture,compound fracture of 3.9%.Direct signs of orbital wall fracture was depression,bone fracture,dislocation,bone crushing,abnormal curvature of the orbital wall.Indirect signs of fracture of the medial rectus was swelling,vague and / or displacement,ethmoid sinus effusion,orbital contents of the hernia,orbital product gas,orbital hemorrhage,optic nerve swelling and / or displacement,enophthalmos,exophthalmos,eye eyelid and periorbital soft tissue swelling,product gas.Conclusion： Multi-slice spiral CT scan and MPR,3D imaging of orbital wall fracture has important diagnostic value.
