Topographic anatomy of facial artery and medial canthus artery / 中华医学美学美容杂志

ABSTRACT

Objective To explore the layers of the facial and angular arteries between the orbital notch and the antegonial notch.Methods Anatomical studies were performed on 5 cases of adult cadavers (10 sides).Parallel lines were drawn on each cadaver through the position of the orbital incise,inner canthus,above of wing nose,nasal wing point,mouth angle,anterior incise.When the region of the arterial level changes,the parallel lines could be temporarily divided.The levels of the arteries that appeared on every horizontal line were recorded.Results The surface artery between the orbital notch (including the supraorbital notch) and the inner canthus (including the inner cantholes) was mainly in the orbicularis muscle layer.In the middle of the inner canthus and the highest point of the nasal wing,1/3 of the arteries were mainly walking in the orbicularis orbicularis muscular layer,and the next 1/3 were mainly located in the superficial layer or subcutaneous fat layer of the orbicularis oculi muscle.The highest point of the nose wing was found in the middle of the subcutaneous fat.The main line between the top of the nose and the lower part of the nose was deep in the subcutaneous fat.At the bottom of the nose,the main line was located in the fat layer of the zygomaticus,the zygomaticus maximus.In the middle and upper part of the nose and the middle of the mouth,a third of the main lines were walking in the lower fat layer (from shallow to deep) under the zygomaticus,and the next 1/3 segment was found in the subcutaneous fat deep.On the outside of the corner of the mouth,the main line was walking the subcutaneous fat layer or the lower fat layer of the platysma.Conclusions This study preliminarily clarifies the walking level of the facial artery from the upper orbital notch and the anterior notch of the angle.Bearing in mind the depth and the location of the vasculature within each zone,clinical practitioners can tailor their injection techniques to prevent vessel injury and avoid cannulation.
