case_images: The tumor was fully exposed through a wide endonasal endoscopic transsphenoidal approach, the dura was incised, debulking of the tumor was achieved, and the skull base defect was reconstructed using a free dural underlay graft and a pedicelled nasoseptal flap for the final skull base reconstruction (Figure 2).
