BACKGROUND The resection of tuberculum sellae meningiomas poses a challenge particularly when dealing with the medial aspect of the optic nerve. Dissection of the tumor off the optic nerve is usually carried out in the blind spot "behind" the optic nerve. We describe a contralateral approach for asymmetric tuberculum sellae meningiomas, allowing direct visualization of the medial optic nerve. METHOD Contralateral lateral supraorbital approach was performed, and complete tumor resection was achieved without any injury to the optic nerve. CONCLUSION The contralateral approach for asymmetric tuberculum sellae meningioma is an efficient technique allowing improved visualization of the medial optic nerve.

我该怎么做：对侧蝶鞍上入路治疗鞍结节脑膜瘤。

背景技术特别是在处理视神经的内侧方面时，蝶鞍状脑膜瘤的切除提出了挑战。视神经解剖肿瘤通常是在视神经“后面”的盲点进行的。我们描述了不对称的蝶鞍脑膜瘤的对侧入路，允许直接可视化内侧视神经。方法采用对侧眼眶上外侧入路，实现了完整的肿瘤切除，对视神经没有任何损伤。结论不对称性蝶鞍脑膜瘤的对侧入路是一种有效的技术，可以改善内侧视神经的可视化。
