The clinical significance of HRCT in the fracture of optic canal

Objective:To evaluate the clinical significance of HRCT in the detection of fracture of optic canal.Methods:12 cases of the optic nerve trauma were performed HRCT,which was processed with bone algorithm reconstruction.The CT features of fractures of optic canal were analyzed.Results:14 fractures of optic canal in 12 cases were demonstrated by CT,which included 8 cases of fractures in medial wall (6 in sphenoid sinus,2 in ethmoid sinus),3 in lateral wall,1 in Optic Strut,3 in superior wall and 5 in inferior wall.The fractures of optic canal were divided into four types on CT:①lineal②depressed③comminuted④mixed fractures.9 of 14 fractures of optic canal were part of the skull base fracture.Conclusion:HRCT has an important clinical significance of improving diagnostic ability of fracture of optic canal and warranting the clinical management.
