Pterygoid canal

Dr Henry Knipe et al.

The pterygoid canal, also known as the Vidian canal, is a foramen in the base of skull, located in the sphenoid bone, inferomedial to the foramen rotundum. It transmits the Vidian artery and Vidian nerve from the middle cranial fossa to the pterygopalatine fossa

It is an important structure as involvement of the canal in inflammatory or neoplastic disease can result in pain referred deep to the nasal cavity. Pathological appearances of the pterygoid canal have been described to include effacement, atrophy, and enlargement. It can be difficult to distinguish possible pathological changes from normal anatomical variation.
