ABSTRACT
The development of high-frequency devices and transducers in recent years has enabled the growth of the use of dermatologic ultrasound. Real-time monitoring of the anatomy of the face during the application of aesthetic injectables potentially prevents complications such as vascular occlusions. Injecting physicians starting out in the practice of ultrasound-guided injections are commonly faced with practical questions about its use. In this article, based on the experience with ultrasound-guided filler injections of 2 large clinical centers in 2 countries, the authors summarize the steps involved when setting out to use ultrasound to guide injectable aesthetic procedures, such as fillers and biostimulators. First, the authors discuss factors that guide the choice of equipment and ultrasound transducers to perform the procedures. Next, a detailed discussion on practical issues related to the procedure is provided. The authors then consider the positioning of operators and equipment in the treatment field. The authors conclude by suggesting 2 possible techniques to guide injectable procedures: (1) scan before injecting or (2) scan while injecting.
