Endoscopic transnasal "microsurgery" for suprasellar meningioma involving the anterior communicating artery complex

This video demonstrates endoscopic transnasal "microsurgery" for a suprasellar meningioma involving the anterior communicating artery complex. A 44-year-old woman presented with visual loss due to a suprasellar tumor. Preoperative three-dimensional simulation aided in planning the expanded skull base exposure. Using bimanual dissection and meticulous vascular handling, the tumor was resected while preserving critical structures. Skull base reconstruction employed multilayered techniques with dural suturing. This case illustrates how endoscopic microsurgical strategies enable safe resection of anatomically challenging tumors, combining the benefits of endoscopic visualization and microsurgical precision for optimal outcomes.
