Dr. Ines Verner demonstrates how to visualize the facial, superior and inferior labial arteries. High-definition vascular imaging using Color Doppler allows her to visualize the locations and avoid intervascular injections.
we would like to visualize the facial artery but also the superior and inferior labial arteries so these are the things that we would like to visualize the facial artery we can find it actually here on the mandibular border and we can see here it is some pulsations there so here it's quite deep and it's quite a big vessel and it actually is quite deep here we would like to visualize the superior and inferior labial arteries as to know where to inject the lips if we want to be more superficial or more deep to the vessels and as you know there are many many anatomical differences so for around 78 of patients the artery will be submucosal in 20 intra muscular and in some patients it's going to be subcutaneous so very superficial so we really need to map as there are many many different differences between people regarding this these two arteries superior and inferior labial arteries so i can see the artery here so i can i can already check the depths of the artery here the supe this is the superior labial artery and it's around four millimeters depth so i can go either superficial to that or deeper to that level so i will be in the correct plane and not risk the intravascular injection and if i want to check for the inferior labial artery actually i can do it again yep so the inferior labial artery is here and we can see we can measure again and it's around five millimeters four and a half millimeters in depth so also here i should be more superficial to be able not to actually have the intravascular injection so we've been mapping the temporal area we also mapped the vessels in the nasolabial fold and also the superior and inferior labial arteries as these are the danger zones in the face another area is the glabellar area which we also have to map each time we are injecting fillers in that area as not to risk intravascular injection and risk blindness the other points i'm going to make are in the marionette lines and here i know that the vessel the inferior labial artery is at four millimeter depth so here i can actually be much more superficial in this area i will go superficial there is not so much space in this area as the mucosa is quite close so i'm going to be superficial and in this way i'm not going to heat the vessel so i'm going to go here and i'm going to be very very superficial on the plane and as you can see i'm not touching anything no vessel is touched and i can actually inject here here again i'm gonna be superficial and i'm good the same on the other side very superficial here because the vessel was at four millimeters so i'm not going to touch it so that's it
