In our opinion, the ideal approach should be tailored to the individual patient according to the tumor size,
lateral extension, optic canal involvement, extent of vascular encasement and surgeon’s experience. We
currently make the selection of the approach on a case-by-case basis without following a specific algorithm.

CONCLUSION
Endoscope-assisted or endoscope-controlled supraorbital keyhole transcranial approach is a highly
effective approach for excision of anterior skull base meningiomas. It offers a minimally invasive option
that overcomes the pathoanatomical constraints that preclude using an extended endoscopic endonasal
approach in some cases.
