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.
This article outlines the relevant surgical anatomy and the different surgical steps of this approach.
The medial orbito-frontal approach offers a full exposure of the superomedial intraconal quadrant and avoids crossing the plane of the optic nerve.
In selected intraconal tumor cases, this transcranial epidural intraorbital approach is a straightforward corridor through reliable landmarks that can be routinely performed.
多种病变可累及眼眶。必须有多种手术入路以实现360度的手术视野。对于占据眶内上象限的肿瘤，选择眶内侧-额部入路是有理论依据的。
本文概述了该入路的相关手术解剖及不同手术步骤。
眶内侧-额部入路能充分暴露眶内上象限，且避免穿过视神经平面。
在特定的眶内肿瘤病例中，这种经颅硬膜外眶内入路是一条通过可靠标志的直接通道，可常规开展。
