Anatomy Monday: Pterygomaxillary Fissure


This week I have a few pantomographs showing the pterygomaxillary fissure.  The pterygomaxillary fissure is the lateral opening to the pterygopalatine fossa. The pterygomaxillary fissure presents as a radiolucent inverted teardrop shape just lateral to the maxilla. It has a a radiopaque edge.
