Abstract
Surgical management of ventral foramen magnum meningiomas (FMMs) is challenging due to intervening neurovascular structures. The endoscopic endonasal transclival approach provides a direct access, offering a potential route to achieve Simpson Grade 1 resection while minimizing brainstem retraction. We detail the technical nuances of a binostril, four-handed EEA for a ventral FMM. We explain the key anatomical landmarks required for safe decompression, including clival drilling limits, the identification of pre-medullary neurovascular structures, and the execution of a multilayered reconstruction. The EEA is a safe alternative for ventral FMMs in cases without significant lateral or caudal extension.
