Exploration of Spiral CT Scan Technology in Optic Canal Fracture

Objective To evaluate the clinical application of spiral CT in the fracture of optic canal. Methods A total of 24 patients with optic nerve trauma were performed spiral CT scan and bone arithmetic reconstruction, all the CT appearances of fracture were analyzed. Results Six cases were double optic canal fracture, 13 cases were single optic canal fracture, while 5 cases did not find any fracture sign. Among them, 7 cases were optic canal inboard wall fracture, 5 cases with optic canal outboard wall fracture, 2 with visual cone fracture, 3 with upper wall fracture and 2 with down wall fracture. Conclusions Spiral CT scan technology can improve detection rate of optic canal fracture significantly, and dependable imaging diagnosis can be offered in clinical treatment.
