Med Plasty treatment simulations are authored against established facial arterial anatomy and the documented high-risk injection zones described in the aesthetic-medicine literature. The interactive reference below maps the vessels and danger zones relevant to injectable treatment planning.
Interactive reference
Select any labelled artery to review its origin, course, and vascular territory, together with its clinical significance in injectable treatment. The danger-zone overlay marks injection sites with a documented risk of intravascular compromise.
Vascular basis of risk
The face is perfused by branches of the external and internal carotid arteries. Because the two systems anastomose freely, inadvertent intra-arterial injection at almost any facial site can embolise toward the ophthalmic circulation.
The facial, superior and inferior labial, lateral nasal, angular, infraorbital, and superficial temporal arteries arise from the external carotid system. Together they perfuse the perioral region, midface, and lateral face — the territories most frequently addressed with dermal filler.
The supraorbital, supratrochlear, and dorsal nasal arteries are terminal branches of the ophthalmic artery, arising from the internal carotid. Their anastomoses with the angular artery form the retrograde embolic pathway implicated in filler-associated visual loss.
The glabella, nasal dorsum, nasolabial fold, and temple overlie vessels in direct or anastomotic continuity with the ophthalmic circulation. These sites account for the majority of reported vascular adverse events, from cutaneous ischaemia to irreversible visual loss.
This is a generalised anatomical illustration intended for consultation and education. It is not a per-patient scan or a diagnostic tool. Arterial course and calibre vary considerably between individuals; every patient must be assessed directly by a qualified practitioner before any procedure.
The same anatomy map is built into the Med Plasty simulator, alongside AI-generated treatment previews, to support the conversation between practitioner and patient.
