Abstract
The branches of the terminal portion of the maxillary artery emanate from the pterygopalatine fossa through bony foramina or fissures to supply the deep facial structures. The radiographic anatomy of the fossa and its openings are reviewed. The normal vascular anatomy is defined and correlated with postmortem injections and a dried skull model.The consistent arteriographic distribution of these vessels is determined by their relationship to the facial skeleton. These branches conform to the bony partitions of several important facial compartments, namely, the maxillary antrum, nasal cavity, and pterygopalatine fossa. Changes in topography may indicate pathologic alterations in these boundaries.
