Abstract
BACKGROUND: A variety of lesions can affect the orbit. Surgical approaches must be available to provide 360 degrees of access. For tumors occupying the superomedial intraconal quadrant, there is a rationale to selecting the medial orbito-frontal approach. METHODS: This article outlines the relevant surgical anatomy and the different surgical steps of this approach. RESULTS: The medial orbito-frontal approach offers a full exposure of the superomedial intraconal quadrant and avoids crossing the plane of the optic nerve. CONCLUSION: In selected intraconal tumor cases, this transcranial epidural intraorbital approach is a straightforward corridor through reliable landmarks that can be routinely performed.
