Infraorbital vein: drainage of the midface
Quick facts
- Definition
- Vein that drains part of the midface and follows the course of the infraorbital nerve.
- Passage
- Passes through the infraorbital foramen, below the lower edge of the orbit.
- Drainage
- Communicates with the facial vein and the pterygoid plexus.
- Neighbors
- Infraorbital nerve, infraorbital artery and the muscles that elevate the upper lip.
- Relevance in HOF
- Midface, cheekbone and tear trough area, where bleeding and bruising are possible.
The infraorbital vein is a vein of the midface that follows the course of the nerve and artery of the same name. It emerges in the region of the infraorbital canal and foramen, just below the lower edge of the orbit, and drains part of the cheek, the upper lip and the lower eyelid. Its position makes it relevant in any midface analysis.
Where does it run?
In broad terms, the infraorbital neurovascular bundle exits the infraorbital foramen, in the maxilla, and spreads out under the muscles that elevate the upper lip. The vein, together with the infraorbital artery and the infraorbital nerve, follows this path. Its branches communicate with the facial vein and, more deeply, with the pterygoid plexus, forming connections that are part of the complex venous drainage of the face. The exact position and caliber vary from person to person.
| Bundle structure | Function |
|---|---|
| Infraorbital nerve | Sensation of the midface and upper lip |
| Infraorbital artery | Blood supply to the area |
| Infraorbital vein | Drainage of the midface |
| Infraorbital canal | Bony passage of the bundle |
Why does it matter in HOF?
The midface is a highly sought-after area, with cheekbone projection, tear troughs and nasolabial folds. The presence of the infraorbital bundle and a dense vascular network means that bruising and ecchymosis are possible and that anyone working there should know the anatomy. Hyaluronic acid with hyaluronidase available, conservative volume and preparation for complications are part of safe practice, at the discretion of the qualified professional.
Warning signs
A bruise that grows quickly, disproportionate pain or skin color changes are signs that call for reassessment. See also the approach to bruising to distinguish an expected bruise from a vascular complication.
The vein and the tear trough
The tear trough lies just above, and the vessels of the lower eyelid and the midface are connected. This reinforces caution in the area, which is considered high vascular risk in procedures with dermal filler.
In Harmy
The Cheekbone and Tear Trough points of the app's marking are in the territory of this vein. The projection is illustrative, does not represent vessels or predict bruising, and anatomical planning remains the professional's responsibility.
Also called: vein of the infraorbital foramen.
Frequently asked questions
Can the infraorbital vein cause a bruise in midface procedures?
Yes, like any vessel in the area. The venous and arterial network of the face is rich, and bruising and ecchymosis are described risks in cheekbone and infraorbital procedures.
