Abstract
- Background.
- Vascular complications from dermal fillers are uncommon but potentially devastating. Understanding three-dimensional facial anatomy is central to prevention.
- Methods.
- Anatomical literature, cadaveric studies and adverse event registries were reviewed to identify high-risk vascular zones and safer injection planes.
- Results.
- The glabella, nasolabial fold and temple represent zones with the highest reported incidence of intra-arterial injection. Sub-periosteal and deep supra-periosteal placement, with cannula-led delivery in superficial planes, is associated with reduced reported risk.
- Conclusion.
- Anatomically guided technique is the strongest modifiable risk factor in dermal filler safety.
Keywords: facial anatomy, dermal fillers, vascular occlusion, injection technique, cannula, complications
1. Introduction
Mastery of facial vascular anatomy underpins safe dermal filler practice. This article summarises high-risk zones and safer planes for injection.
2. Vascular Anatomy
The supratrochlear, dorsal nasal and angular arteries form an anastomotic network with retrograde access to the ophthalmic artery, explaining the rare but reported risk of blindness.
3. Technique Considerations
Slow injection, low-pressure delivery, aspiration where appropriate, and preferential use of cannulas in danger zones reduce — but do not eliminate — vascular risk.
4. Conclusion
Detailed anatomical knowledge, combined with disciplined technique, remains the single most important factor in filler safety.
