The pterygomaxillary fissure is a fissure of the human skull. It is vertical and descends at right angles from the medial end of the inferior orbital fissure; it is a triangular interval formed by the divergence of the maxilla from the pterygoid process of the sphenoid. It connects the infratemporal with the pterygopalatine fossa and transmits the terminal part of the maxillary artery.
