Abstract
The supratrochlear artery represents a terminal branch of the ophthalmic artery. Cosmetic interventions may traumatize it, resulting in a circulation in the lesion in glabellar region and in the medial aspect of the forehead.This review article aims to synopsise the existing knowledge of the anatomy of the supratrochlear artery in close correlation with minimally invasive cosmetic procedures in the facial area such as soft-tissue filler injections. Their possible adverse effects and their safe application based on the topographic anatomy were included.A literature review was performed in PubMed/Medline online medical database.The superficial course of the supratrochlear artery, as well as the rich, variable anastomotic network that it forms with the supraorbital, angular and dorsal nasal artery raise clinical questions in the case of soft-tissue filler injections in the nasoglabellar and central forehead area. Accidental cannulation of the supratrochlear artery and ultimately, the risk of embolization of the central retinal artery in a retrograde fashion might lead to injury with questionable cosmetic results.Although the risk of complications from the use of soft tissue fillers is considered rare, once happen, the results could be devastating for the quality of life. Thus, the comprehension of the anatomy of the supratrochlear artery is paramount for the health practitioners.
Highlights
BackgroundThe supratrochlear artery (STA) is a terminal branch of the ophthalmic artery (OA) which in turn is the first intracranial branch of the internal carotid artery (ICA) [1]
A certain number of adverse effects was observed varying from mild local skin irritation to vision loss and even cerebral infarction soon after the application of cosmetic interventions in the area [4,5]
The purpose of this study is to present a review of the available literature concerning the STA's anatomy in correlation with its clinical significance in cosmetic medical procedures
Summary
The supratrochlear artery (STA) is a terminal branch of the ophthalmic artery (OA) which in turn is the first intracranial branch of the internal carotid artery (ICA) [1]. Accurate knowledge of the anatomy of the STA is of crucial importance. Statistical analyses from the American Society of Plastic Surgeons, demonstrate that there is an increasing demand for minimally invasive cosmetic procedures in facial area [3]. A certain number of adverse effects was observed varying from mild local skin irritation to vision loss and even cerebral infarction soon after the application of cosmetic interventions in the area [4,5]. The purpose of this study is to present a review of the available literature concerning the STA's anatomy in correlation with its clinical significance in cosmetic medical procedures
