Particular attention was given to the normal radiographic appearance of the pterygoid canal as well as to its anatomic variants and its relationship to the paranasal sinuses. Three radiographic signs of involvement of the pterygoid canal were detected: disappearance, enlargement, and narrowing. Moreover, a brief correlation between pluridirectional tomography and CT was made. Diagnostic accuracy in evaluating the bony lesions is the same with both techniques, but CT is superior to pluridirectional tomography in evaluating involvement of the soft tissues. ER -
