Abstract

Objective: Although the supraorbital (SO) keyhole approach has a wide range of indications, its routine usefulness with the advance of current technology has not been fully evaluated. In an attempt to address this issue, a cadaveric morphometric analysis to the supra- and parasellar regions was performed, comparing the standard Pterional craniotomy (PT) with the SO keyhole.

Methods: ETOH-fixed and silicone-injected human cadaveric heads were used. SO (n = 8) and PT craniotomies (n = 8) were performed. Pre- and post-dissection CT, along with pre-dissection MRI scans were also completed for neuro-navigation purposes, aimed to verify predetermined anatomical landmarks selected for morphometric analysis.

Results: Notwithstanding the smaller craniotomy, the SO approach allowed optimal anatomical exposure when compared to the PT approach. With 30° of head rotation, the SO keyhole showed a wider surgical field of the suprasellar region.

Conclusions: Using detailed preoperative image-guided surgical planning, the SO keyhole approach offered an appropriate alternative route to the supra- and parasellar regions, compared to the PT craniotomy.

眶上锁孔与翼状入路：形态解剖学研究。

目的：尽管眶上锁孔（SO）方法具有广泛的适应症，但随着当前技术的进步，其常规用途尚未得到充分评估。为了解决这个问题，我们对尸体的眶上和眶旁区域进行了形态计量分析，比较了标准蝶骨开颅术（PT）和眶上锁孔法：方法：使用经 ETOH 固定和硅胶注射的人类尸体头颅。方法：使用经 ETOH 固定和硅胶注射的人体尸体头颅，分别进行 SO（n = 8）和 PT（n = 8）开颅术。为了进行神经导航，还完成了开颅前和开颅后的 CT 以及开颅前的 MRI 扫描，目的是验证为形态计量分析选定的预定解剖标志：尽管开颅切口较小，但与 PT 切口相比，SO 切口能获得最佳的解剖暴露。在头部旋转30°的情况下，SO钥匙孔显示出更宽的鞍上区域手术视野：结论：通过详细的术前图像引导手术规划，与PT开颅术相比，SO锁孔方法为髌上和髌旁区域提供了一个合适的替代路径。
