Only in recent years new available technologies, the redefinition and refining of intervention techniques, and clinical research studies have widened the spectrum of fat applications in aesthetic and reconstructive surgery. Fat grafting is nowadays one of the most used techniques in plastic reconstructive surgery, as primary method or as an ancillary procedure. The optimized ratio of fat survival has led to standardized techniques followed by most practitioners.The aim of this book is to present up-to-date technologies used for fat extraction, and fat harvesting: latest tools are evaluated examining pros and cons. All recent techniques in aesthetic and reconstructive surgery and their outcomes are described in a clear, comprehensive manner; chapters present the latest research results in stem cell and regenerative medicine, their application to plastic and reconstructive surgery, in particular for hand surgery, ulcer, and capsule contractures in post breast augmentation procedures. Related specific techniques as breast fat transfer, breast hybrid implant, fat transfer and buttock fat transfer are also discussed. Safety issues in fat transfer procedures are examined accurately, particularly those involving buttock fat transfer. Each procedure is completed by a scientific analysis of the main reasons for complications, how to prevent them and the safety guidelines recommended as golden standard to be followed. The surgical part contains clinical cases related to each chapter topic, videos, and all chapters have a box with take home messages. An invaluable tool for correct decision-making for clinicians, fellows and residents in plastic surgery, Fat Transfer in Plastic Surgery focuses on indications, applications and surgical techniques for each individual body district, and safe and reliable procedures in the application of latest technology.
