Endoscopic transorbital approach for the management of spheno-orbital meningiomas: A systematic review and meta-analysis.

Introduction: Meningioma is the most common benign tumor in the central nervous system and may arise from the sphenoid wing region. The tumor can involve the cavernous sinus medially, periorbital and orbital apex structures anteriorly, and infratemporal fossa inferiorly. Surgical approaches more currently used include the fronto-temporal approach, the pterional approach, and even the frontotemporal-orbitozygomatic approach.
