Surgical Therapy of Non-Skull Base Meningiomas.

In a previous chapter, the surgical management of skull base meningiomas were discussed. However, the most common meningiomas that are diagnosed and operated on are non-skull base tumors located in the parasagittal/parafalcine region and convexity, and more rarely along the tentorium, and in an intraventricular location. These tumors present their own unique set of challenges given their unique anatomy and tend to be more biologically aggressive compared to skull base meningiomas, thereby reinforcing the importance of obtaining a gross total resection if possible, in order to delay recurrence. In this chapter we will cover the surgical management of non-skull base meningiomas with technical considerations for tumors located in each of the anatomical areas listed above.
