200. Face – topographico-anatomical specificities.

Covers the topographic anatomy of the face's subregions, beginning with the infratemporal fossa: its boundaries, the foramina and passages that open from it, and its contents such as the masticatory muscles, mandibular nerve branches and buccal fat pad. It then moves through the facial, infraorbital, zygomatic, mental and buccal regions, giving borders, blood supply and innervation for each, and notes clinical points such as dental anaesthesia and pain from maxillary sinus disease.

INFRATEMPORAL Region

The infratemporal fossa is an extracranial space located deep to the ramus of the mandible. It contains the masticatory muscles, branches of the mandibular nerve and maxillary artery and the venous pterygoid plexus. It also contains part of the parotid gland and part of the buccal fat pad.

Boundaries

  1. 1 Cranially: sphenoidal bone – infratemporal surface of the greater wing, temporal bone – squamous part
  2. 2 Ventrally: maxillary tuberosity
  3. 3 Dorsally: continues as the prestyloid space
  4. 4 Medially: sphenoidal bone – lateral plate of pterygoid process
  5. 5 Laterally: ramus of mandible

Passages

  1. 1 Foramen ovale
  2. 1.1 Mandibular nerve
  3. 1.2 Venous plexus of foramen ovale
  4. 2 Foramen spinosum
  5. 2.1 Middle meningeal artery and vein
  6. 2.2 Meningeal branch of the mandibular nerve
  7. 3 Mandibular foramen
  8. 3.1 Inferior alveolar nerve
  9. 3.2 Inferior alveolar artery and vein
  10. 4 Pterygomaxillary fissure
  11. 4.1 Maxillary artery
  12. 4.2 Venous tributaries to the pterygoid plexus
  13. 5 Petrotympanic fissure
  14. 5.1 Chorda tympani
  15. 5.2 Anterior tympanic artery and vein
  16. 5.3 Anterior ligament of malleus
  17. 6 Foramen lacerum / sphenopetrosal synchondrosis
  18. 7 Foramen petrosum
  19. 7.1 Lesser petrosal nerve
  20. 8 Alveolar foramina of maxillary tuberosity
  21. 8.1 Posterior superior alveolar branches of the maxillary nerve
  22. 8.2 Posterior superior alveolar arteries and veins
