目的为开展视神经管新型手术提供精细的解剖学基础。方法在大体解剖学研究基础上,应用改进的火棉胶包埋技术对前颅底区域进行连续的三维薄切片,通过两者的有机结合,深入研究视神经管区域精细的解剖结构与复杂的毗邻关系。结果对视神经管区域解剖结构与毗邻关系显示良好精确。中鼻甲根部上缘至视神经管距离左侧为(28.0±5.0)mm,右侧为(29.0±6.0)mm。蝶窦下壁厚度左侧为(3.0±0.9)mm,右侧为(2.7±0.9)mm,视神经管与蝶窦或(和)筛窦间壁厚度左侧为(1.0±0.3)mm,右侧为(1.0±0.4)mm。结论经鼻、蝶窦或(和)筛窦入路行视神经管手术安全可行。
Objective To provide a fine anatomic basis for the new surgery of optic canal. Methods Based on the general anatomical study, an improved anterior cutaneous basement was made with three-dimensional thin sections by using improved collodion technique. Through the organic combination of the two, the detailed anatomic structure of the optic canal area and the complex adjacent structures relationship. Results The anatomical structure and adjacent relationship of optic canal area showed good accuracy. The distance from the upper edge of the middle turbinate to the optic canal was (28.0 ± 5.0) mm on the left and (29.0 ± 6.0) mm on the right. The thickness of the sphenoid sinus wall was (3.0 ± 0.9) mm on the left and (2.7 ± 0.9) mm on the right. The thickness of the optic canal and sphenoid sinus or (and) ethmoid sinus was (1.0 ± 0.3) (1.0 ± 0.4) mm. Conclusion Transnasal, sphenoidal or (and) ethmoid sinus approach is feasible and safe.
