Lateral surface of right zygomatic bone Markup for lateral view of zygomatic bone
Medial wall of the orbit. In terms of skeleton, the medial wall of the orbit is the most complex one. Note the orbital process of palatine bone that forms only a small fraction of the wall, but is a useful anatomical landmark for endoscopic endonasal surgical approach to the medial wall of the orbit*.
The list of terms: Processus frontalis maxillae – Frontal process of maxilla
Os lacrimale – Lacrimal bone
Lamina orbitalis ossis ethmoidalis – Orbital plate of ethmoid bone
Processus orbitalis ossis palatini – Orbital process of palatine bone
Corpus ossis sphenoidalis – Body of sphenoid bone
Foramen ethmoidale anterius – Anterior ethmoidal foramen
Foramen ethmoidale posterius – Posterior ethmoidal foramen
Canalis opticus – Optic canal
