Orbits share 3 walls with the sinuses, frontal sinuses on the supero-medial aspects of the orbits, ethmoid sinuses medially and maxillary sinuses inferiorly. Between the ethmoids and the orbits, there is lamina papyraecea which is a very thin bone. Between the maxillary sinus and the floor of the orbit, ...
