Weiss, MD Dallas,Texas,andCarmel,Indiana Summary: The American Academy of Dermatology and the American Society of Plastic Surgeons, with the support of other sister societies, conducted the Facial Soft-Tissue Fillers: Assessing the State of the Science conference in December of 2009. The American Academy of Dermatology and the American Society of Plastic Surgeons established a panel of leading experts in the field of soft-tissue fillers—from researchers to clinicians—and other stakeholders for the conference to examine and discuss issues of patient safety, efficacy, and effectiveness in relation to the approved and off-label use of soft-tissue fillers, and other factors, including the training and level of experience of individuals administering fillers. This report represents the systematic literature review that examines comprehensively the available evidence and gaps in the evidence related to soft-tissue fillers, to inform and support the work of the state-of-the-science conference panel. This evidence-based medicine review will serve as the foundation for future evidence- based medicine reports in this growing field.
