Background: There are multiple approaches for the anatomical and surgical dissection of the orbit, these approaches are made through the walls of the orbit. The most common approach is through the roof of the orbit. In recent years the anatomical transmaxillary approach to the orbit has gained significance, most notably because of its present and future surgical applications. The aim of this study is to provide a guide for the anatomical dissection of the orbit through the transmaxillary approach. Results: ten orbits were dissected through the transmaxillary approach. The orbits were dissected following a five steps procedure, and the anatomy was illustrated with high quality images. Conclusions: a detailed guide for the anatomical dissection of the orbit through the transmaxillary approach was conceived. This guide is meant to be easy to reproduce and serve the reader as a tool to further his anatomical knowledge of the region, increasing the precision and safety of future surgical procedures.
