The purpose of this anatomical study is to illustrate the microscopic and endoscopic anatomy of the anterior communicating artery complex as viewed through three keyhole approaches (keyhole pterional, lateral supraorbital and supraorbital) and to compare them. Each approach was carried out once on each side in five glutaraldehyde-fixed human cadaveric heads. A microscope and microscope-endoscope combination were used to grade access and visualization of the structures qualitatively using a previously published surgical exposure grading system. All three approaches provided good access and visualization of ipsilateral structures in the anterior communicating artery complex, but the pterional keyhole and the lateral supraorbital approaches gave the best access. Exposure of contralateral structures was limited overall, but was enhanced somewhat by the use of the endoscope.
本解剖研究的目的是通过三种锁孔入路（翼点锁孔、外侧眶上和眶上锁孔）来展示前交通动脉复合体的微观和内镜解剖，并对其进行比较。在 5 个戊二醛固定的人体头颅标本上，每种入路均在每侧进行一次。使用显微镜和显微镜内镜组合，使用先前发表的手术暴露分级系统对结构进行定性分级，以评估进入和可视化程度。三种入路均能很好地进入和观察到前交通动脉复合体的同侧结构，但翼点锁孔和外侧眶上锁孔入路提供了最佳的进入途径。总体而言，对侧结构的暴露有限，但使用内镜可以在一定程度上增强。
