Sphenopalatine Foramen


In the adult skull this foramen travels via the pterygopalatine fossa inside the posterior section of the superior meatus of the nose.

It afterwards sends out:

  • Sphenopalatine artery
  • Sphenopalatine vein
  • Superior nasal nerves
  • Nasopalatine nerves

The sphenopalatine notch divides the processes of the superior margin of the palatine bone, which is afterwards transformed into the sphenopalatine foramen via the inferior surface of the body of the sphenoid bone.

2. Sending outwards

  • Nasopalatine nerve
  • Posterior superior nasal nerves
  • Sphenopalatine artery and vein
