摘要
Background/Objectives: Modern breast reconstruction has undergone substantial evolution, with implant-based, pedicled autologous, and free autologous techniques. The purpose of this study is to review the current state of the art in free autologous breast reconstruction, highlighting advancements in the types of flaps, donor site selection, techniques, and functional restoration. Methods: A literature review was conducted using PubMed to capture studies related to well-known free flaps that are used for breast reconstruction. Studies for each flap type were reviewed and sorted for inclusion into one of six categories: (1) clinical outcomes, (2) comparison studies of alternative flaps, (3) preoperative planning, (4) flap classifications and perfusion zones, (5) technique descriptions, and (6) time and cost analyses. Results: The majority (77%) of articles included were written on various types of abdominally based free flaps, including TRAM, DIEP, and SIEA flaps. These studies indicated an evolution in technique over time to minimize donor site morbidity, improve patient-reported and functional outcomes, improve efficiency, and expand clinical indications. The remaining 23% of articles discussed alternative flap choices, including PAP, TUG, S/IGAP, and LAP flaps. Studies highlighted technical challenges and the evolution of techniques to make these flaps more accessible, as well as how to combine flaps to expand clinical indications. Conclusions: Autologous breast reconstruction has evolved significantly, with advancements in techniques such as robotic-assisted surgery, multi-flap reconstruction, bipedicled flaps, and neurotization. This review highlights the current best practices while acknowledging ongoing challenges and the potential for future innovations in microsurgery, nerve regeneration, and personalized medicine, which hold promise for further refining outcomes.
