Superior ophthalmic vein and the drainage of the face
- Vein
- Highlighted area
Quick facts
- Formation
- At the upper inner corner of the orbit, by communication with the angular vein and the veins of the forehead.
- Course
- Runs back through the orbit, alongside the ophthalmic artery.
- Exit
- Through the superior orbital fissure.
- Destination
- Cavernous sinus, inside the skull.
- Relevance in HOF
- Anatomical basis of the danger triangle of the face and of the attention paid to infections in the center of the face.
The superior ophthalmic vein is the main vein of the orbit. It forms at the upper inner corner of the orbit, where it communicates with the angular vein and the veins of the forehead, runs back through the orbit alongside the ophthalmic artery, exits through the superior orbital fissure and drains into the cavernous sinus, inside the skull. This link between the skin of the center of the face and an intracranial venous sinus is the anatomical basis of the danger triangle of the face.
How does the face drain toward the skull?
| Pathway | Veins involved | Destination |
|---|---|---|
| Main superficial | Angular vein, facial vein | Internal jugular vein, in the neck |
| Through the orbit | Angular vein, superior ophthalmic vein | Cavernous sinus |
| Through the orbit, lower portion | Inferior ophthalmic vein | Cavernous sinus and pterygoid plexus |
| Deep | Deep facial vein, pterygoid plexus | Cavernous sinus, through emissary veins |
Most of the time, blood from the nose, upper lip and cheeks drains down the facial vein to the neck. The communication through the orbit exists in parallel, and the direction of flow can vary with pressure, position and swelling in the area.
Why does it matter in HOF?
- Infection in the center of the face: the upper lip, nose and the area between the eyes also drain through the ophthalmic route. That is why infections in this area, including after a procedure, deserve attention and early treatment.
- Asepsis: strict asepsis and care with biofilm in fillers of the center of the face are not just good practice, they are safety.
- Herpes and active lesions: performing a procedure over skin with an active infection in the area is a widely cited relative contraindication. The topic is covered in cold sores and filler.
- Reading swelling: significant, progressive periorbital swelling, with pain, fever or visual change, is not ordinary procedure-related swelling.
And the risk of injecting into the vein?
The most feared vascular event in HOF is arterial: occlusion of branches of the ophthalmic artery, which can lead to vision loss. The superior ophthalmic vein sits inside the orbit and is not a target of any aesthetic procedure. What makes it relevant is the venous communication with the skin of the center of the face, not direct injection into it. The overview is in infection and biofilm after filler.
How does it show up in the assessment?
- Medical history: recurrent skin infections, herpes, active sinusitis and immunosuppression.
- Examination of the area: active lesions, inflamed acne or sores on the nose and upper lip.
- Post-procedure guidance: explain the warning signs to the patient and how to get in touch.
Also called: vena ophthalmica superior, SOV.
Frequently asked questions
What is the cavernous sinus and why is it a concern?
It is a set of venous channels on each side of the sella turcica, at the base of the skull, through which pass the nerves that move the eyes and the internal carotid artery. An infection that reaches it can cause cavernous sinus thrombosis, a rare and serious condition.
Does the superior ophthalmic vein have valves?
Classically, the veins of the face and orbit are described as lacking effective valves, which allows flow in both directions depending on pressure. More recent studies describe valves in some facial veins, but the communication with the cavernous sinus remains the basis of the risk concept.
