Exploring efficacy: A comprehensive review of extended transsphenoidal approach in anterior skull base meningiomas.

Background: Anterior skull base meningiomas can cause significant symptoms such as mass effect and neuropsychological decline, necessitating surgical resection. The endoscopic extended transnasal approach has emerged as a minimally invasive alternative to craniotomy, offering a means to address these tumors despite challenges due to the proximity of critical neurovascular structures and the high risk of complications such as cerebrospinal fluid (CSF) leaks. This systematic review and meta-analysis evaluate the safety and efficacy of extended transsphenoidal techniques in anterior skull base meningiomas.
