Abstract
Background The aim of our study was a pictorial documentation of the anatomical structures of
the orbit.
Methods We performed a transmaxillary endoscopic approach in nine formalin-fixed human heads.
We identified and documented the anatomy of the inferior part of the orbit.
Results The first intraorbital anatomical landmark was the inferior rectus muscle, from which
important structures medially and laterally could be identified. Anatomical structures
and their relation to each other were documented and presented as illustrative figures.
Conclusion Knowledge of the topographic anatomy of the inferior part of the orbit could be sufficiently
imparted by our illustrations. The presented transmaxillary approach allowed a wide
overview of the anatomical structures located in the inferior part of the orbit. Our
pictorial documentation may provide neurosurgeons more safety and the opportunity
to become familiar with the endoscopic anatomy.
