Introduction and Epidemiology The most common tumors affecting the sellar, suprasellar, and parasellar regions include pituitary adenomas, Rathke cleft cysts, craniopharyngiomas, meningiomas, germ cell tumors, and gliomas involving the hypothalamus or optic chiasm. Management is dictated according to each specific…
Summary of Key Points The endoscopic transnasal approaches provide a direct surgical trajectory to anteriorly located lesions at the craniocervical junction. Clinical series demonstrate low rates of postoperative infection after endoscopic transnasal approaches to intradural pathology despite nasal contamination. Endoscopic…
Introduction Endoscopic reconstruction following transtuberculum and transplanum approaches to suprasellar pathology is an area of ongoing evolution. The cornerstones of endoscopic repair remain similar to open surgical approaches with the aims of reestablishing separation of the cranial vault and sinonasal…
Key Points Incidence Pituitary tumors represent approximately 10% to 15% of primary intracranial tumors. Biologic Characteristics The vast majority of pituitary tumors are benign and may be functional (i.e., secrete excess hormones) or nonfunctional. The pathogenesis of pituitary tumors is…
