Sphenopalatine foramen
The sphenopalatine foramen connects the nasal cavity and the pterygopalatine fossa, transmitting the nasopalatine nerve, posterior superior nasal nerves, and sphenopalatine artery and vein.
Gross anatomy
It is formed at the junction of the sphenopalatine incisure (palatine bone) with the sphenoid bone in the medial wall of the pterygopalatine fossa. The sphenopalatine foramen opens into the superior nasal meatus.
