Ventrally based meningiomas at the craniovertebral junction can be challenging tumors to remove because of their deep location anterior to the lower brainstem and upper cervical spinal cord, and close association with complex neurovascular structures. The extreme lateral transcondylar approach provides excellent access and exposure to anterior and anterolateral intradural tumors involving the region of the craniovertebral junction, including the lower third of the clivus, the foramen magnum, and the upper cervical spine. This approach allows safe access for removal of these difficult tumors without any neural retraction. In this operative video manuscript, the author demonstrates an illustrative step-by-step technique for microsurgical resection of a ventrally based meningioma extending from the foramen magnum to C-2 using the extreme lateral transcondylar approach. The operative technique and surgical nuances, including the surgical approach, intradural tumor removal, and cranial base reconstruction, are illustrated in this video atlas.

颅颈交界区腹侧脑膜瘤由于其位于下脑干和上颈髓的前方，与复杂的神经血管结构关系密切，因此是一种具有挑战性的肿瘤。极外侧经髁突入路为涉及颅颈交界区的前、前外侧硬脊膜内肿瘤提供了极好的入路和显露，包括斜坡下部、枕骨大孔和上颈椎。这种方法允许安全地切除这些困难的肿瘤，而无需任何神经牵拉。在这个手术视频手稿中，作者演示了使用极外侧经髁突入路切除从枕骨大孔延伸至 C-2 的腹侧脑膜瘤的分步技术。手术技术和手术要点，包括手术入路、硬脊膜内肿瘤切除和颅底重建，都在这个视频图谱中进行了说明。该视频可在此处找到：http://youtu.be/4uvPpEtEShU。
