Head and Neck

Arterial Supply

  • The left common carotid artery (CCA) arises directly from the aorta, while the right CCA arises from the brachiocephalic trunk.

  • Each CCA bifurcates at the level of T4 into two branches:
    1. 1.

      External carotid artery (ECA): Gives multiple branches, including the superficial temporal, lingual, and maxillary

    2. 2.

      Internal carotid artery (ICA): Passes through the carotid foramen into the inside of the skull and forms the circle of Willis; see Chapter 3, Neuroanatomy, for more details


Venous Drainage

  • Face: Drains into the internal jugular vein (IJV) via the facial vein

  • Brain: Drains into the dural venous sinuses; see Chapter 3, Neuroanatomy.

  • Note: The facial vein is connected to the cavernous sinus, so an infection of the face may be transmitted intracranially, causing cavernous sinus thrombosis.

Carotid Sheath and Neck Triangles

  • Carotid sheath: Contains common carotid artery (medially), internal jugular vein (laterally), and vagus nerve (posteriorly)

  • Triangles:...
