Orbital Wall Fracture Diagnosis by Multi-slice Spiral CT

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.
