Abstract

Endoscopic endonasal resection of orbital intraconal retrobulbar lesions has gained popularity in last few years. In this region, knowledge of anatomy is paramount to orient and guide the surgeon. The aim of this chapter is to describe the anatomy of the orbit from the endoscopic endonasal perspective. Two surgical cases are reported to enlighten the advantages and limits of this approach. We also provided detailed description of the surgical technique, emphasizing the important anatomical landmarks with cadaveric dissection pictures.

At the end of the chapter, the reader will be able to select lesions that can be approach through this route, considering their location and relationship to key anatomical landmarks, thus maximizing its efficacy and reducing its morbidity.
