In order to analyze each pterygopalatine fossa and canal separately, the lateral skull roentgenogram should be obtained with the head rotated 10° away from the true lateral. Following facial trauma, angulation or interruption of the pterygopalatine fossa and canal indicates fractures through the maxilla going as far posteriorly as the pterygoid processes and probably involving them also. Juvenile nasopharyngeal angiofibroma may widen the pterygopalatine fossa and canal indicating that the tumor is no longer confined to the nasophanynx but has infiltrated into the pterygopalatine fossa and canal. A case is reported of anterior bowing of the anterior wall of the pterygopalatine fossa and canal caused by squamous cell carcinoma.
