摘要
目的 :为经蝶进路手术提供影像解剖学资料。方法 :对 5 0具成人头颅标本行冠状位、矢状位及水平位薄层CT扫描。观测鞍区手术最常用的 2种进路经鼻外筛窦蝶窦进路及经鼻中隔蝶窦进路的相关影像解剖。结果 :前鼻棘至蝶窦前壁的平均距离 :左侧 :5 6 .5± 5 .9mm ;右侧 :5 4.9± 7.2mm ;鼻根点至蝶窦前壁的平均距离 :左侧 :44 .3± 5 .6mm ;右侧 :44 .0± 6 .5mm ;前鼻棘至鞍底中点的平均距离 :左侧 :74.5± 6 .4mm ;右侧 :73 .8± 6 .8mm ;鼻根点至鞍底中点的平均距离 :左侧 :6 0 .9± 7.2mm ;右侧 :6 0 .2± 7.8mm。 2种进路的解剖距离相差 12~ 14mm。结论 :CT影像解剖测量对选择不同的手术进路更具实际的指导意义。
To provide imaging anatomy basis for the transnasal sphenoid approach.Methods:50 adult head specimens were studied through thinner CT scanning with coronal,sagittal,axial position.The most two common used approach of saddle area operation (extemal ethmoid approach and transnasal sphenoid approach) was observed.Results:The distance from the front wall of sphenoid sinus to the nasal spine was 56.5±5.9 mm for left and 54.9±7.2 mm for right, 44.3±5.6 mm for left and 44.0±6.5 mm for right to nasion.The average distance from middle point of sphenoid saddle bottom to nasal spine was 74.5±6.4 mm for left and 73.8±6.8 mm for right,60.9±7.2 mm and 60.2±7.8 mm to nasion.There was 12~14 mm anatomy distance between the external ethmoid approach and transnasal sphenoid approach.Conclusion: These imaging anatomy measured with CT was instructive significance to choose the operation approach.
