Blood Vessels of the Face and Scalp


Facial artery
  • Arises from the external carotid artery just above the upper border of the hyoid bone.
  • Passes deep to the mandible, winds around the lower border of the mandible, and runs upward and forward on the face.
  • Gives rise to the ascending palatine, tonsillar, glandular, and submental branches in the neck and the inferior labial, superior labial, and lateral nasal branches in the face.
  • Terminates as an angular artery that anastomoses with the palpebral and dorsal nasal branches of the ophthalmic artery to establish communication between the external and internal carotid arteries.
Superficial temporal artery
  • Arises behind the neck of the mandible as the smaller terminal branch of the external carotid artery and ascends anterior to the external acoustic meatus into the scalp.
  • Accompanies the auriculotemporal nerve along its anterior surface.
  • Gives rise to the transverse facial artery , which passes forward across the masseter between the zygomatic arch above and the parotid duct below.
  • Also gives rise to zygomatico-orbital, middle temporal, anterior auricular, frontal, and parietal branches.
Facial vein
  • Begins as an angular vein by the confluence of the supraorbital and supratrochlear veins. The
  • angular vein is continued at the lower margin of the orbital margin into the facial vein.
  • Receives tributaries corresponding to the branches of the facial artery and also receives the
  • infraorbital and deep facial veins.
  • Drains either directly into the internal jugular vein or by joining the anterior branch of the retromandibular vein to form the common facial vein , which then enters the internal jugular vein.
    Communicates with the superior ophthalmic vein and thus with the cavernous sinus , allowing a route of infection from the face to the cranial dural sinus.
Retromandibular vein
  • Is formed by the union of the superficial temporal and maxillary veins behind the mandible.
  • Divides into an anterior branch , which joins the facial vein to form the common facial vein, and a posterior branch , which joins the posterior auricular vein to form the external jugular vein.
