The pterygoid canal (also vidian canal) is a passage in the sphenoid bone of the skull leading from just anterior to the foramen lacerum in the middle cranial fossa to the pterygopalatine fossa.[1]
It transmits the nerve of pterygoid canal (Vidian nerve), the artery of the pterygoid canal (Vidian artery), and the vein of the pterygoid canal (Vidian vein).
