目的:观察测量鞍区及颅中窝底骨性结构的解剖位置,为神经内窥镜和显微神经外科在该区的直接手术提供解剖学依据。方法:对２２例成人尸头标本鞍区及颅中窝底骨性结构进行解剖学观察,比较翼点入路和额下入路到该区的解剖距离。结果:额下入路到鞍区的解剖距离最近是(４５．６３±０．７８)ｍｍ(３８．０２~５２．５０ｍｍ)和(７３．１０±０．５６)ｍｍ(６５．２４~８２．５６ｍｍ),而翼点入路分别为(３４．７５±０．８１)ｍｍ(２４．０８~５０．５８ｍｍ)和(６７．９９±０．６８)ｍｍ(６０．１６~７５．６０ｍｍ)。翼点内板到颅中窝底的各个孔的最大距离是(６２．４６±０．５７)ｍｍ(５５．８６~７０．０８ｍｍ),最大垂直角度是(３９．８２±１．５２)°(２９．６°~５５．７°)。结论:鞍区和颅中窝底的骨性结构可为神经内窥镜和显微神经外科手术操作提供解剖标志,翼点入路比额下入路到鞍区的距离缩短约１０~１５ｍｍ两者具有明显差异(Ｐ＜０．０１)。
OBJECTIVE: To observe the anatomic location of the sellar structure in the saddle area and middle cranial fossa and to provide anatomic evidence for the direct operation of neuroendoscopy and microsurgical neurosurgery in this area. Methods: Twenty-two adult cadaver heads were used to anatomize the sellar structures of the saddle area and middle cranial fossa. The anatomical distances between the pterional approach and the inferior approach were compared. Results: The anatomical distances from the inferior approach to the saddle were (45.63 ± 0.78) mm (38.02 ~ 52.50mm) and (73.10 ± 0.56) mm (65.24 ~ 82 .56mm), while the pterional approach were (34.75 ± 0.81) mm (24.08 ~ 50.58mm) and (67.99 ± 0.68) mm (60.16 ~ 75.60mm) . The maximum distance of each hole in the pterygoid midplane to the bottom of skull midpiece is (62.46 ± 0.57) mm (55.86 ~ 70.08mm) and the maximum vertical angle is (39.82 ± 1.52) ° (29.6 ° to 55.7 °). CONCLUSIONS: The bony structures of the sella and cranial fossa at the base provide anatomical landmarks for neuroendoscopic and microsurgical surgical procedures. The distance between the pterional approach and the sellar area is reduced by about 10-15 mm Who had significant difference (P <0.01).
