Managing Injectable Fillers in the Long-Term Aesthetic Patient: Contemporary Approaches and Surgical Considerations.

Summary: Facial aging is a multifaceted process arising from changes in skin quality, soft-tissue volume, underlying bony anatomy, and the cumulative impacts over time of factors such as expressive animation, environmental exposures, and gravity. Although historically facial rejuvenation focused primarily on surgical correction of tissue descent, enhanced understanding of volume loss as a major contributor to aging has led to the widespread adoption of soft-tissue fillers as a nonsurgical adjunct-or stand-alone treatment-for signs of facial aging. These treatments are popular with patients due to their low risk profile; minimal downtime; avoidance of scarring; and, often, reversibility. The modern aesthetic surgeon must develop strategies for managing patients across their lifetime, integrating nonsurgical and surgical approaches while maintaining natural-appearing results. This includes understanding how to plan filler for longevity and safety, modifying filler placement in previously treated areas, determining optimal timing for surgical intervention, and managing the transition between different treatment modalities. The integration of these various approaches requires not only product and technical expertise but also careful attention to patient education and long-term planning. This article provides a comprehensive framework for managing facial aesthetic patients throughout their treatment journey, with particular focus on the role of hyaluronic acid fillers at different life stages. We present strategies for assessment, treatment selection, and technical execution across different age groups and anatomical zones, supported by long-term case examples. Special attention is given to the interaction between injectable fillers and surgical procedures, as well as considerations for maintaining natural-appearing results over time.
