The Supratrochlear Artery Revisited: An Anatomic Review in Favor of Modern Cosmetic Applications in the Area

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.

Reconstruction of a large nasal defect using a folded forehead flap: a case report

“…Three weeks after surgery, flap division under local anesthesia was performed. Studies in the literature recommend that, at 3 weeks after surgery, if the flap color becomes purple after pressing the pedicle lightly, it is appropriate to wait another week and perform the division 4 weeks after surgery [8,11]. In this case, when the flap was lightly tightened at week 3, the color was well maintained, so the division was carried out at week 3.…”

“…After approximately 3 weeks, flap division is performed to separate the pedicle [6,7]. The main blood supply of the forehead flap is the supratrochlear artery, which branches from the ophthalmic artery [8,9]. In some cases, minor revision surgery is required to restore the natural contour and symmetry [10].…”

Surgical Strategies for Eyelid Defect Reconstruction: A Review on Principles and Techniques

“…Anatomically, the STA emerges from the ophthalmic artery and travels superomedially under the orbicularis oculi muscle. The STA provides a consistent cutaneous branch in a position 1.18 ± 0.36 cm distal to the supraorbital rim [ 42 ], which allows the forehead flap to be trimmed as an ultrathin flap from 2 cm superior to the orbit and modified into an islanded flap [ 43 ] or tunneled flap [ 44 ] to conform to the complex landscape around the orbit.…”

“…Khoảng cách trung bình từ ĐM trên ròng rọc đến đường giữa tại bờ trên cung mày là 19,16 ± 7,49mm, từ ĐM trên ròng rọc đến góc mắt trong tại bờ trên cung mày là 4,75 ± 3,75mm. Theo Loukas (2020), ĐM trên ròng rọc xuyên qua ổ mắt tại vị trí cách đường giữa khoảng 17 -22 mm và ở khoảng cách trung bình 12 mm cao hơn so với góc mắt trong (MC) [5]. Kết quả này tương tự NC của chúng tôi.…”
