Commentary on: The Change of Plane of the Supratrochlear and Supraorbital Arteries in the Forehead—An Ultrasound-Based Investigation

Abstract

When considering dermal filler injections, the brow and low forehead have been considered an area of high reward but also high risk for intravascular injection and therefore a relative “no-fly zone” especially for the inexperienced. The supraorbital (SOA) and supratrochlear artery (STA) as well as the less consistent superficial paracentral and central arteries are implicated in intravascular injection. Details relating to the transition of the SOA and STA from the orbit to subcutaneous fat and the precise location with respect to discrete ligamentous structures and fascial planes have not been well described and are confusing, in part due to the complexity of the fascial planes in this zone. The authors of this study have set out to clarify the 2- and 3-dimensional (3D) relation of the SOA and STA to these anatomic planes as they pass from deep to superficial.1 Key to understanding their findings and visualizing a potential clinical application is a thorough comprehension of the anatomy.
