Abstract

Background

Foramen magnum meningiomas (FMMs) represent significant neurosurgical challenge because of their intimate relationship with highly functional and vital neurovascular structures.

Method

We discuss and illustrate technical nuances to resect type 3 FMMs with anterolateral dural attachment, causing compression and displacement of the medulla oblongata, accessory nerve and upper cervical spinal cord, with encasement of vertebral artery, through far lateral approach.

Conclusion

Proper extradural preparation, early cerebrospinal fluid drainage, sectioning of dentate ligament, working between the nerve rootlets from caudal to rostral and from lateral to medial can enhance the safety and extent of resection.

我是怎么做的。枕骨大孔脑膜瘤。外科原则为一个独特的病理过渡区。

背景：枕骨枕骨大孔脑膜瘤（fmm）由于其与高功能和重要的神经血管结构密切相关，是神经外科的重大挑战。方法：我们讨论并说明3型fmm伴硬脑膜前外侧附着的技术细节，通过远侧入路切除延髓、副神经和颈上脊髓压迫和移位，伴椎动脉被套。结论：适当的硬膜外准备、早期脑脊液引流、齿状韧带切开术、神经根间从尾侧到吻侧、从外侧到内侧操作可提高手术的安全性和切除范围。

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.
