WebThe Agger nasi cells are the most anterior ethmoidal air cells. Their location is anterior, lateral, and inferior to the frontal recess [1, 11]. Infraorbital ethmoidal (Haller) cells are ethmoidal cells that extend downward under the medial floor of the orbit adjacent to and above the maxillary sinus ostium lateral to the infundibulum [1, 7]. WebThe ethmoid boneis exceedingly light and spongy, and cubical in shape; it is situated at the anterior part of the base of the cranium, between the two orbits, at the roof of the nose, and contributes to each of these cavities. mitchell todd venice fl

This is an anterior ethmoid cell that pneumatizes anterior, posterior, or around the anterior ethmoidal artery on the orbit's roof. If the frontal sinus is extensively pneumatized, the supraorbital ethmoid cell may be a part of the sinus' posterior wall, requiring bony septation to separate it from the sinus.
