Supraorbital vein: drainage of the forehead
Quick facts
- Definition
- Vein that drains the lateral part of the forehead and anterior scalp and runs toward the inner corner of the eye.
- Drainage
- Joins the supratrochlear vein to form the angular vein.
- Key connection
- Communicates with the superior ophthalmic vein and, through it, with the cavernous sinus.
- Neighbors
- Supraorbital artery and nerve, frontalis muscle and eyebrow.
- Relevance in HOF
- Forehead and eyebrow: an area of vascular risk and bruising.
The supraorbital vein is a vein of the forehead that drains the skin, muscles and anterior scalp. It descends alongside the supraorbital artery and nerve, toward the inner corner of the eye. There, it joins the supratrochlear vein to form the angular vein, the origin of the facial vein.
Where does it run and what does it connect to?
The vein runs over the frontalis muscle, in the forehead, near the eyebrow. Near the orbit, it communicates with the superior ophthalmic vein, which links the drainage of the face to that of the inside of the orbit. This connection, described by anatomy, is one of the reasons for attention to infections of the upper third of the face and helps explain why the area is treated with care.
| Neighboring structure | Relationship |
|---|---|
| Supraorbital artery | Accompanies the vein and supplies the forehead |
| Supraorbital and supratrochlear nerves | Provide sensation to the forehead |
| Supraorbital foramen | Bony passage of the bundle |
| Angular vein | Formed by the junction with the supratrochlear |
Why does it matter in HOF?
The forehead and eyebrow are heavily treated areas, usually with toxin and occasionally with other approaches. The vascular anatomy of the area is rich and communicates with the circulation of the eye. For that reason, the upper third is considered sensitive, especially the glabella and the periorbital region. Knowledge of the anatomy, conservative volume, preparation for complications and hyaluronidase available when hyaluronic acid is used are part of safety. Management is the responsibility of the qualified professional, according to the rules of their professional council.
Bruising on the forehead
Because it has a rich superficial vascular network, the forehead can develop ecchymosis and swelling after punctures. The bruise can travel down by gravity toward the eyelids in the following days, which frightens the patient. It is worth warning them beforehand. See also bruising.

The Glabella point of the app's marking is in this neighborhood. The projection is illustrative, and does not represent vessels or predict complications. Harmy does not replace anatomical assessment.
Also called: lateral frontal vein (in some descriptions).
Frequently asked questions
Is the supraorbital vein connected to the inside of the skull?
Indirectly. It communicates with the superior ophthalmic vein, which drains into the cavernous sinus. These connections, without important valves in some facial veins, are part of the reason for caution with infections and injections in the upper third.
