Veins of the face and scalp
The superficial veins of the face and scalp drain to the internal and external jugular veins and communicate, through veins without valves, with the cavernous sinus and other intracranial venous sinuses.
Key points
- Facial vein: supratrochlear + supraorbital → IJV.
- Superficial temporal + maxillary → retromandibular (in the parotid).
- Posterior retromandibular + posterior auricular → EJV.
- Danger triangle → superior ophthalmic vein → cavernous sinus.
- IJV: anterior cardinal vein. EJV: secondary channel.
- Vein: thin wall, adventitia thickest, valves.
- Veins hold ~70% of the blood.
