The pterygoid plexus is of considerable size, and is situated between the Temporalis and Pterygoideus externus, and partly between the two Pterygoidei.
Tributaries received
It receives tributaries corresponding with the branches of the maxillary artery.
Thus it receives the following veins:
- sphenopalatine
- middle meningeal[1]
- deep temporal
- pterygoid
- masseteric
- buccinator
- alveolar
- some palatine veins
- a branch which communicates with the ophthalmic vein through the inferior orbital fissure
Relations
This plexus communicates freely with the anterior facial vein; it also communicates with the cavernous sinus, by branches through the foramen Vesalii, foramen ovale, and foramen lacerum.
