Coronal Relationships of the Orbits, Nasal Cavities, and Frontal and Maxillary Sinuses

Surgical Correlation


Coronal relationships of the orbits, nasal cavities, and frontal and maxillary sinuses. The eyeball and contents in the anterior half of the orbit have been removed. Apical structures that can be seen include the optic nerve, ophthalmic artery, origins of the four recti muscles, lateral, medial, inferior, and superior (not labeled), and orbital fat. In this view, the nasal cavity is related laterally at the level of the middle turbinate to the orbit superiorly, with the ethmoid air cells intervening, and the maxillary sinus inferiorly. The inferior turbinate lies medial to this sinus. The orbital floor represents the roof of the maxillary sinus. The nasal cavity is divided longitudinally by the nasal septum. The frontal sinus may have extensions into the roof of the orbit as demonstrated in this specimen. (Image courtesy of PA Rubino)
