Dissection of nasal fossae, nasal pharynx, and palate
Relations of nasal passages, maxillary sinus, palate and sphenopalatine ganglion, left lateral view
The zygomatic bone has been completely removed and the lateral bony walls of the maxillary sinus (20) and inferior nasal meatus (21) have been cut away. The sinus is unusually small. The connections of the sphenopalatine ganglion (17) have been dissected.
  1. Tendon of lateral rectus muscle
  2. Inferior oblique muscle
  3. Infraorbital nerve and artery within infraorbital canal (note branch of artery to inferior oblique muscle)
  4. Middle nasal concha
  5. Mucosa of nasal septum
  6. Infraorbital margin
  7. Inferior nasal concha (anterior tip resected)
  8. Hard palate
  9. Anterior nasal spine maxillae
  10. Muscles of upper lip (sectioned in midline)
  11. Alveolar process of maxilla (edentulous)
  12. Levator palpebrae superioris muscle and superior rectus muscle
  13. Sheath of optic nerve
  14. Ophthalmic nerve (V)
  15. Inferior rectus muscle
  16. Upper pointer: Sphenoid sinus (cut open) Lower pointer: Vidian nerve of pterygoid canal (bony canal opened)
  17. Sphenopalatine ganglion
  18. Terminal portion of internal maxillary artery (cut off)
  19. Superior posterior alveolar nerve
  20. Mucosal membrane maxillary sinus
  21. Superior posterior alveolar artery and mucosal membrane inferior nasal meatus
  22. Branches of anterior palatine nerve
  23. Greater palatine artery
  24. Remnant of lateral plate of pterygoid process
  25. Tunica palatine mucosa
  26. Tongue
