Where is pterygoid venous plexus located?
Veins of the head and neck. The pterygoid plexus (/ˈtɛrɪɡɔɪd/; from Greek pteryx, “wing” and eidos, “shape”) is a venous plexus of considerable size, and is situated between the temporalis muscle and lateral pterygoid muscle, and partly between the two pterygoid muscles.
What is the pterygoid venous plexus?
The pterygoid venous plexus is an extensive valveless plexus of veins that parallels the medial two thirds of the maxillary artery on the lateral aspect of the medial pterygoid muscle, within the infratemporal fossa.
What is the significance of the pterygoid plexus of veins in dentistry?
It is connected to the cavernous sinus and the pharyngeal venous plexus. It is an important region because of the potential to spread dental infection; it can also be inadvertently penetrated when administering a block injection of the posterior superior alveolar nerve, potentially resulting in a haematoma.
What makes up the pterygoid plexus?
The pterygoid venous plexus (plural: plexuses) is a small intercommunicating cluster of venules that is intimately related to the lateral pterygoid muscle, lying both intramuscularly and around the muscle. The plexus is formed by very small veins that are the venous counterparts to the branches of the maxillary artery.
Does pterygoid plexus drain into cavernous sinus?
The superior ophthalmic vein drains directly into the cavernous sinus through the superior orbital fissure. The pterygoid plexus communicates with the cavernous sinus through the foramina ovale, spinosum, and rotundum.
Where is the Pterygoid process?
The pterygoid processes or pterygoid plates are paired posteroinferior projections of the sphenoid bone.

What is the Pterygoid region?
The pterygoid fossa is an anatomical term for the fossa formed by the divergence of the lateral pterygoid plate and the medial pterygoid plate of the sphenoid bone.
What is the function of the pterygoid process of the sphenoid bone?
The lateral pterygoid plate of the sphenoid (or lateral lamina of pterygoid process) is broad, thin, and everted and forms the lateral part of a horseshoe like process that extends from the inferior aspect of the sphenoid bone, and serves as the origin of the lateral pterygoid muscle, which functions in allowing the …

What does the pterygoid plexus drain?
The pterygoid plexus drains many deep structures of the head, including the palate, nasal cavity, paranasal sinuses, nasopharynx, auditory tube and deep parts of the scalp in the temporal region. It is continued by a short maxillary vein, which lies deep to the neck of the mandible.
What is the pampiniform venous plexus?
A cluster of veins near a male’s testicles is called the pampiniform venous plexus. Another group of veins known as the pterygoid plexus is located on both sides of the face near the jaw. Many veins come together to form this venous plexus, such as the buccinator, alveolar, masseteric, sphenoplalatine, pterygoid, and the middle meningeal vein.
