Expanded endonasal transsphenoidal surgery for the re-section of tuberculum sellae meningioma. description of surgical technique and review of literature

Abstract

Meningiomas with originating from tuberculum sellae, sphenoid platform, and optic chiasmatic groove are collectively called as tuberculum sellae meningiomas (TSMs) and they are accounted for 5 to 10% of all intracranial meningiomas, which invade the optic canals and lead to visual impairment by displacing the optic nerves upward and laterally. Except presence of many transcranial microsurgical approaches, introduction of endoscopes with highest magnification and gaining much experience in this have made the endonasal route feasible for the resection of tuberculum sellae meningiomas. There are various case reports and mixed publication series discussing this approach. Despite pituitary adenomas, craniopharyngiomas, the literatures describing the surgical steps of endoscopic endonasal transsphenoidal surgery for the resection of tuberculum sellae meningiomas in detail are lacking
