Endoscopic Endonasal Transsphenoidal Approach for Resection of Tuberculum Sella and Planum Sphenoidale Meningiomas: A Snapshot of Our Institutional Experience.

Introduction: Meningiomas of the tuberculum sellae and planum sphenoidale represent a subgroup of anterior skull base tumors that comprise approximately 5%-10% of all intracranial meningiomas. Most of the patients report with failing vision, so early surgical decompression either transcranial and/or endonasal approach is recommended. The endonasal route allows for direct coagulation of the tumor meningeal supply and extensive resection of dural attachments, and importantly, provides an inferior to superior access to the infrachiasmatic region that facilitates complete tumor removal without encountering the optic nerve.
