Endoscopic Endonasal Approach for Clival Chordoma with Subarachnoid Invasion: a 2D Step-by-Step Operative Video.
Chordomas are slow-growing, low-grade, locally invasive, and locally aggressive tumors. They peak at 40-60 years of age, with a male preponderance (2:1). ⋯ An endoscopic endonasal transclival approach was performed and gross total removal was achieved (Video 1). The patient had an uneventful recovery with no deficits, and he was then sent to proton beam therapy.
