描述

The maxillary sinus is a large pyramidal cavity, within the body of the maxilla:

Projecting into the floor of the antrum are several conical processes, corresponding to the roots of the first and second molar teeth;in some cases the floor is perforated by the fangs of the teeth. The infraorbital canal usually projects into the cavity as a well-marked ridge extending from the roof to the anterior wall; additional ridges are sometimes seen in the posterior wall of the cavity, and are caused by the alveolar canals.

The size of the cavity varies in different skulls, and even on the two sides of the same skull.
