This review outlines the current FDA regulatory pathways relevant to AI applications in plastic surgery, including the 510(k), De Novo, and Premarket Approval processes. We discuss the FDA's Digital Health Center of Excellence, established in 2020, which serves as a central resource for developers of AI-based medical devices. The unique challenges of regulating adaptive AI technologies in plastic surgery are examined, with particular focus on the FDA's \"total product lifecycle\" approach and real-world performance monitoring requirements. We highlight the importance of Good Machine Learning Practices (GMLP) and the collaborative framework developed by FDA, NIST, and international regulatory bodies. For plastic surgeons and researchers developing AI tools, we provide practical recommendations including early FDA engagement, emphasis on algorithm transparency and explainability, and strategies for addressing bias in training datasets.

This systematic review assesses its clinical efficacy, safety profile, patient satisfaction, and future advancements. A comprehensive search of studies published between January 2010 and October 2024 identified 45 clinical trials and cohort studies meeting inclusion criteria, which focused on measurable outcomes such as wrinkle improvement and circumference reduction. HIFU demonstrated significant efficacy in skin tightening, particularly in the lower face, neck, and periorbital regions, with improvements in skin laxity ranging from 18% to 30%. For body contouring, studies documented a reduction in circumference between 2.5 cm and 4.5 cm, notably in the abdomen and thighs. Compared to mild surgical outcomes, HIFU provided effective non-invasive lifting with a favorable safety profile; fewer than 5% of patients reported transient erythema, swelling, or mild discomfort. Advances in HIFU technology, such as parallel-beam ultrasound, have improved treatment precision and patient comfort. While HIFU has demonstrated consistent results across different anatomical areas, standardization of treatment protocols remains a key challenge, particularly regarding optimal energy settings and patient selection criteria. Additionally, further research is needed to establish its long-term efficacy and explore its applications across diverse skin types. HIFU continues to be a promising alternative to surgical interventions, enhancing skin rejuvenation and body contouring with minimal downtime.
