Abstract
Anterior cranial base meningiomas have traditionally been addressed via frontal or
frontolateral approaches. However, with the advances in endoscopic endonasal treatment
of pituitary lesions, the transphenoidal approach is being expanded to address lesions
of the petrous ridge, anterior clinoid, clivus, sella, parasellar region, tuberculum,
planum, olfactory groove, and crista galli regions. The expanded endoscopic endonasal
approach (EEEA) has the advantage of limiting brain retraction and resultant brain
edema, as well as minimizing manipulation of neural structures. Herein, we describe
the techniques of transclival, transphenoidal, transplanum, and transcribiform resections
of anterior skull base meningiomas. Selected cases are presented.
