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.
Pantomograph – right pterygomaxillary fissure noted as yellow area
Pantomograph – right pterygomaxillary fissure as a radiolucent inverted teardrop area lateral to the maxilla
Pantomograph – right and left pterygomaxillary fissures visible
If you have any questions about the pterygomaxillary fissure, please leave them below. Thanks and enjoy!
