摘要

背景：我们描述了安全切除 3 型枕骨大孔脑膜瘤的技术，该肿瘤的附属神经根和椎动脉向背侧移位，限制了腹侧进入肿瘤：方法：部分切除附属神经根可能有助于创造更大的工作空间。在脊髓附属神经根部局部放置利多卡因可减轻斜方肌收缩，促进肿瘤切除的进一步进展：结论：在 CN XI 的情况下，通过移动或部分切断小根，在下颅神经之间创建安全的工作走廊，有利于通过远侧入路切除肿瘤。

How I do it: safe resection of a complex type 3 foramen magnum meningioma with dorsal displacement of the neurovascular bundle.

Background: We describe techniques for safe resection of a Type 3 foramen magnum meningioma with dorsal displacement of the accessory nerve rootlets and vertebral artery which limits ventral access to the tumor.

Method: Partial sectioning of the accessory nerve rootlets may help create larger working space. Topical lidocaine placement on the rootlets of the spinal accessory nerve may mitigate trapezius muscle contraction and facilitates further progress throughout tumor resection.

Conclusion: Creating safe working corridors between the lower cranial nerves through mobilization or partial sectioning of rootlets in the case of CN XI facilitates tumor resection through a far lateral approach.

期刊介绍： The journal "Acta Neurochirurgica" publishes only original papers useful both to research and clinical work. Papers should deal with clinical neurosurgery - diagnosis and diagnostic techniques, operative surgery and results, postoperative treatment - or with research work in neuroscience if the underlying questions or the results are of neurosurgical interest. Reports on congresses are given in brief accounts. As official organ of the European Association of Neurosurgical Societies the journal publishes all announcements of the E.A.N.S. and reports on the activities of its member societies. Only contributions written in English will be accepted.
