Expanded Endonasal Approach for the Resection of Midline Suprasellar Craniopharyngiomas

Abstract

Objective: Craniopharyngiomas are notoriously difficult to treat. Surgeons must weigh the risks of aggressive resection against the long-term challenges of recurrence. Because of their parasellar location, often extending well beyond the sella, these tumors challenge vision, pituitary, and hypothalamic functions. New techniques are needed to improve outcomes in patients with these tumors while decreasing morbidity. The techniques and approach used for the endoscopic endonasal resection of suprasellar craniopharyngiomas are described based on a novel tumor classification scheme.
