Results: Lateral extradural approach could be used to expose the second and third branches of trigeminal nerve,trigeminal ganglion,posterior vertical segment of the intrapetrosal ICA,abducent nerve and horizontal segment of the intrapetrosal ICA;lateral intradural approach could be used to expose the lateral,anteroinferior and posterosuperior venous spaces,almost all the cranial nerves within the cavernous sinus and horizontal segments of the intracavernous ICA;superior approach could be used to expose the medial,lateral and posterosuperior venous spaces,medial side of the anterior genu,anterior vertical and clinoidal segments of the intracavernous ICA and the lateral side of the hypophysis.

结果：外侧硬膜外入路可用于显露三叉神经第2、3支，三叉神经节，海绵窦内颈内动脉后垂直段，外展神经及岩骨颈内动脉水平段；侧方硬膜下入路可用于显露海绵窦外侧及前下，后上静脉间隙，以及所有走行在海绵窦内的颅神经和海绵窦内颈内动脉水平段；上方入路可用于显露海绵窦内侧、外侧及后上间隙，海绵窦内ICA水平段、前膝、前垂直段及床突段的内侧面，以及垂体的外侧面。

Results :The deep formal vein,formed by the perforating venous trunk and tributaries of gracilis muscle,converged into the femoral vein 8.6±0.9 cm below the midpoint of inguinal ligament.Its truck was 2.6±0.5 cm long and 6.9±1.1 mm in diameter.In 29 cases,there was 1 valve proximal to the abouchement of the first perforating vein.The deep femoral vein collected the venous blood of the thigh and the knee,the superficial venous blood of the shank.

结果：股深静脉由穿静脉主干及股薄肌支汇合而成，汇入股静脉处位于腹股沟韧带中点下8.6±0.9 cm，主干长2.6±0.5 cm，外径6.9±1.1 mm，29侧各有一个瓣膜位于第一穿静脉汇入处近侧，股深静脉通过其属支收集大腿外侧、后侧、内侧深部及浅静脉回流，并收集膝部深、浅静脉及小腿浅静脉回流。
