Transfacial View of Maxillary Sinus, Nasal Cavity, and Orbital Apex

Surgical Correlation

Transfacial view of maxillary sinus, nasal cavity, and orbital apex. In this coronal section the maxillary sinuses are in view lateral to the nasal cavity. The nasal cavity is divided by the midline nasal septum and from its lateral walls here project the middle and inferior turbinates. The floor of the nasal cavity is the palate. Superiorly, the sphenoid sinuses can be seen within the body of the sphenoid with a septum that divides this space. The planum sphenoidale roofs this sinus. The planum connects the right and left lesser wings which contain the optic canals. The orbital apex is in view here with the optic nerve and ophthalmic artery visible as well. (Image courtesy of AL Rhoton, Jr.)
