    Study Notes

    Venous Drainage of the Head and Neck

    • The venous drainage of the head and neck begins at the head and neck and travels downwards, ending at the superior vena cava.
    • The superior vena cava is the final point of drainage for head and neck blood, and empties into the right atrium of the heart, then right ventricle, then lungs to be oxygenated.
    • The superior vena cava receives blood from several major tributaries, including the left and right jugular veins, vertebral veins, and left and right subclavian veins.

    External Jugular Vein

    • The external jugular vein drains blood from the superficial structures of the face and neck, and has multiple branches which also drain blood from these regions.
    • The posterior external jugular vein is formed from the posterior retromandibular vein and the posterior auricular vein.
    • The maxillary vein drains the palate, nasal cavity, sinuses, and nasopharynx and originates from the pterygoid venous plexus.
    • The posterior auricular vein drains the skin behind the ear.
    • The cervical and suprascapular veins drain the muscles of the neck.
    • The anterior jugular vein is formed by a confluence of multiple superficial submandibular veins, and drains blood from the anterior portion of the neck.

    Internal Jugular Vein

    • The internal jugular vein has multiple branches that drain blood from the face and neck, and it is important to learn the key tributaries for dental relevance.
    • The tributaries can be remembered using the pneumonic, "M.S.L.C.P.I."
      • M = Middle thyroid
      • S = Superior thyroid
      • L = Lingual
      • C = Common facial
      • P = Pharyngeal
      • I = Inferior petrosal sinus
    • Key Tributaries:
      • The inferior petrosal sinus drains large portions of the brain and inner ear.
      • The vein of the cochlear duct drains the cochlea.
      • The meningeal veins drain the meninges of the brain.
      • The pharyngeal venous plexus drains the pharynx.
      • The common facial vein drains the face.
      • The lingual vein drains the tongue.
      • The middle and superior thyroid vein drain the thyroid gland.
