Study Notes

Venous Drainage of the Head and Neck

  • Venous drainage starts from the head and neck and moves downwards, eventually reaching the superior vena cava.
  • The superior vena cava drains into the right atrium of the heart.
  • The main tributaries draining into the superior vena cava are the right and left brachiocephalic veins.
  • The right and left brachiocephalic veins receive blood from the right and left internal jugular veins, right and left subclavian veins, and the right and left vertebral veins.
  • The internal jugular veins receive blood from the brain, skull, oral cavity, and superficial structures of the face and neck.
  • The external jugular vein has multiple branches that drain areas in the face and neck.
  • The posterior external jugular vein forms from the confluence of the posterior retromandibular vein and the posterior auricular vein.
  • The posterior auricular vein drains the skin from behind the ear.
  • The cervical and suprascapular veins drain the muscles of the neck.
  • The anterior jugular vein is formed by the confluence of multiple superficial submandibular veins and drains blood from the anterior aspect of the neck.
  • The internal jugular vein also has many tributaries draining areas in the face and neck.
  • It is not essential to know all of these tributaries; however, dental practitioners should be aware of those with clinical relevance, including the inferior petrosal sinus, veins of the cochlear duct, meningeal veins, pharyngeal venous plexus, and the palatine, pterygoid, facial, and lingual veins.
