Summary: This study evaluated whether echogenic needles improve ultrasound visibility during hyaluronic acid filler injections in the cheek—a high-risk area due to anatomical variability of facial vessels. In a single-patient in vivo setting, 3 types of needles (23G nonechogenic and 23G and 30G echogenic) were tested under ultrasound guidance. Echogenic needles showed better tip and shaft visibility across angles and depths, including dynamic movement. Reviewers noted greater procedural confidence and a reduced need for probe adjustment. These findings suggest that echogenic needles may enhance safety and precision in ultrasound-guided aesthetic procedures.
