The anatomical relationships and morphologic features of the optic canal and the internal carotid artery to the lateral wall of the most posterior ethmoidal cell and the sphenoid sinus in 100 half-skulls swan middle-saggitally were investigated. The results showed: (1) The whole optic canals neighboured with the most ethmoidal cell in 39 cases, with the sphenoid sinus in 43 cases and with both of them in 18 cases; (2) The bulgings of the optic canal formed on the lateral wall of the most posterior ethmoidal cells and the sphenoid sinus were demonstrated in 48 and 47 cases respectively; (3) The marks of the internal carotid artery formed on the lateral wall of the sphenoid sinus were demonstrated in 53%-77% of all cases. The height and the thickness of the bony wall of the bulgings and marks of the optic canal and the internal carotid artery were measured. From our observation it was suggested that the variations of development and composition of the sphenoid-ethmoid sinuses, the bulging or mark of the optic canal and the internal carotid artery on the lateral wall of the most posterior ethmoidal cell and the sphenoid sinus might be the anatomical factors of severe complications in endoscopic ethmoid-sphenoid surgery.
对100个经正中矢状面剖开的半颅骨标本中，视神经管及颈内动脉与最后筛窦外侧壁和蝶窦的解剖关系及形态学特征进行了研究。结果显示：（1）39例视神经管全程紧邻最后筛窦，43例紧邻蝶窦，18例同时紧邻二者；（2）分别有48例和47例在最后筛窦外侧壁及蝶窦出现视神经管隆起；（3）53%-77%的病例在蝶窦外侧壁出现颈内动脉压迹。对视神经管及颈内动脉隆起和压迹处骨壁的高度及厚度进行了测量。根据观察结果提示，蝶筛窦发育及结构的变异、最后筛窦外侧壁及蝶窦处视神经管隆起或颈内动脉压迹可能是鼻内镜筛蝶窦手术严重并发症的解剖学因素。
