Do you know where your fillers go? An ultrasonographic investigation of the lips Julia Vent 1, F. Lefarth 2a, Th. Massing 2b, W.

To date, there are no in vivo investigations on the exact positioning of injectable hyaluronic acid fillers within the lips, and severe complications such as lip hematoma or thromboembolism were rarely published 2,4. The lips, and especially the modiolar region, have vivid blood supply. Thus, it was our aim to define the exact position of hyaluronic acid in the lips immediately after injection, and 18 days postinjection.

Position of injectables depends on the technique such as depot, channel or tower ². • Adverse events such as bruising or thrombosis can be avoided by ultrasonographic control. One should always have hyaluronidase as a rescue medication at hand. • When in doubt, the exact location of injected fillers should be controlled by Doppler ultrasound to avoid injury of arteries or veins. • Maybe intramuscular depots cannot be so well massaged and distributed as depots in connective tissue.
