Background <p>Dermal filler procedures have become increasingly popular in aesthetic medicine; however, they carry the risk of vascular adverse events (VAEs) that can lead to complications such as tissue necrosis and vision loss.</p> Objectives <p>The purpose of this study is to evaluate the clinical utility of high-resolution ultrasound with Doppler analysis (HRUD) in enhancing safety during facial injectable procedures, particularly in high-risk anatomical zones.</p> Methods <p>A review of common clinical scenarios was conducted to outline when and how HRUD can assist in identifying vascular structures, anatomical variants, and vascular changes post-surgery. These scenarios include creating full or focal vascular maps and pre-injection assessment in postsurgical patients. The HRUD procedure was conducted at a reference center for aesthetic ultrasonography.</p> Results <p>HRUD provides real-time visualization of vascular anatomy and its variations, reducing the risk of complications from filler injections. Its use is particularly recommended in high-risk areas such as the forehead, glabella, nose, and pyriform fossa. For postsurgical patients, HRUD aids in navigating altered anatomy, thereby minimizing the risk of VAEs. Conducting a targeted ultrasound evaluation before filler injection can lead to greater precision and fewer complications.</p> Conclusions <p>HRUD is a valuable adjunct to standard aesthetic practices, significantly enhancing patient safety and improving outcomes. Its integration into pre-injection filler protocols is strongly recommended, especially in complex cases or high-risk facial regions.</p> Level of Evidence V <p>This journal requires that authors assign a level of evidence to each article.
