BONES 41 The posterior wall of the maxillary sinus is formed bythe zygomatic plate of the maxilla, which separates itfrom the sphenomaxillary fossa. The proximal or nasal wall is formed chiefly by themaxilla, aided by the inferior turbinated, ethmoid, andpalate bones (Fig. 11). This partition separates the.

At the upper ante-rior portion of this wall is found an oval foramen—theostium maxillare—which affords communication betweenthe maxillary sinus andnniddle meatus, opening directlyinto the hiatus semilunaris. This is the only normal 42 APPLIED ANATOMY opening of the antrum of Highmore, but in certainpathologic conditions more than one opening may bepresent, when the normal opening becomes closed bypressure of the engorged mucous membrane covering the
