ABSTRACT
OBJECTIVE@#To provide efficient support for transnasal endoscopic optic canal decompression with more applied and sufficient imaging study on the optic canal.@*METHOD@#Three-dimensional reconstruction, stereotaxis and related anatomic data of lateral wall of sphenoid-ethmoidal sinuses were got by Multiplanar spiral computed tomographic (MSCT) and AW4.1 software on 14 cases of traumatic optic neuropathy. The data were compared with the results of operations.@*RESULT@#1) The scan plane of nasal-processus clinoideus anterior accorded with optic canal completely; 2) The length of the optic canal were (11.83+/-2.31) mm; 3) Locating mark of optic canal and enhanced internal carotid artery in CT scans which accorded with operations completely were synchronously displayed in sagittal 3D images of lateral wall of sphenoid-ethmoidal sinuses in the whole range.@*CONCLUSION@#The scan plane of nasal-processus clinoideus anterior is the best plane for the CT study of optic canal; Preoperative spatial stereotaxis of optic canal can be simply made by MSCT with good quality to actually reflect personal condition of optic canal and its relationship with lateral wall of sphenoid-ethmoidal sinuses and internal carotid artery exactly and directly. It is better than traditional CT films. And it provides supports for scheduling operation and help getting safe and effective transnasal endoscopic optic canal decompression by sufficient and practical imagings.
