In surgery, better access to the anterior part of the foramen magnum with less risk to the lower brainstem can be obtained by lateral enlargement of the usual posterior opening. This requires exposure and control of the vertebral artery (VA) and the sigmoid sinus (SS) and, for further enlargement, medial transposition of the VA and section of the SS with inferior petrosal resection. This technique has been applied fully or partially in 14 cases of anteriorly located tumors of the foramen magnum. It widens exposure on the anterior aspect of the neural axis and allows work in a nearly frontal plane.
在手术中，通过扩大通常的后入路开口外侧部分，可更好地显露枕骨大孔前部，同时降低对下脑干的风险。这需要暴露并控制椎动脉（VA）和乙状窦（SS），为进一步扩大显露范围，还需将VA向内侧移位，并切断SS及切除岩骨下部。该技术已全部或部分应用于14例枕骨大孔前部肿瘤的手术中。它拓宽了神经轴前方的显露范围，并允许在近乎额状面的平面上进行操作。
