Open Craniotomy for Meningioma

Meningiomas are the most common intracranial extra-axial primary tumor. Although the majority are low grade and slow growing, resection can be technically challenging, particularly when located at the skull base. Appropriate craniotomy and approach selection are of paramount importance to minimize brain retraction, optimize exposure, and achieve complete resection. We aim to summarize various craniotomies and their approaches to meningiomas, and illustrate some nuances in performing these techniques with cadaveric dissection and operative videos.
