In Brief: The authors found a practical intraoperative landmark to localize the optic strut during anterior clinoidectomy and used it as the basis for performing anterior clinoidectomy in two steps: extradural phase and intradural phase. This anatomically based technique can increase the safety of anterior clinoidectomy by providing easily identifiable landmarks and reducing intradural bone drilling, which could put the adjacent neurovauscular structures at risk.
作者发现了一个实用的术中解剖标志，用于在进行前床突切除术时定位视神经管，以此作为两步法进行前床突切除术的基础：硬膜外阶段和硬膜内阶段。这种基于解剖学的技术可以通过提供易于识别的解剖标志和减少可能使相邻的神经血管结构处于危险之中的硬膜内骨钻削来增加前床突切除术的安全性。
