Abstract: BACKGROUND: In recent years, the use of facial soft tissue fillers via cosmetic injections has steadily increased, along with the incidence of adverse events caused by injection vascular occlusion. We aimed to three-dimensionally visualize the anastomosis between facial soft tissue and the vascular system to enhance the safety and effectiveness of facial injections. A cadaver model was used to visualize facial anatomy. A red gelatin-lead oxide contrast agent was perfused to visualize the blood vessels, while 3.75% iodine-potassium iodide was used to stain the soft tissues. Micro-computed tomography scanning was then performed to capture detailed imaging results. RESULTS: We successfully visualized both facial soft tissues and blood vessels simultaneously, including the two-dimensional distribution of vascular tissues and the three-dimensional hierarchical structure of the soft tissue. This allowed accurate assessment of the vascular flow and interconnections in the facial region. CONCLUSIONS: This study provides a detailed three-dimensional representation of the facial vascular anatomy, particularly in the periocular area. By clarifying facial vascular anastomoses, this technique offers a valuable reference for promoting safer and more effective filler injections and reducing the risk of injection-related complications. Providing an interactive, high-resolution vascular dataset of a specific developmental stage. Promoting safe and effective injection of fillers provides a more reliable reference for reducing complications caused by injections.
