The pterygopalatine fossa, also called the sphenopalatine fossa, is a narrow, pyramid-shaped fossa on the lateral aspect of the skull. The fossa is a crossroads between the orbit, nasal cavity, oral cavity, nasopharynx, and middle cranial fossa (Figs 1-5 to 1-7). The pterygopalatine ganglion and the terminal branches of the maxillary artery are situated in its superior part. The pterygopalatine fossa along with the infratemporal and pterygoid fossae are referred to as the retromaxillary space.
