[A brief discussion on microsurgery techniques and free perforator flaps for wound repair]

Microsurgical techniques have evolved from conventional microsurgical anastomosis to supermicrosurgery, and then to robot-assisted surgery, continuously advancing towards greater precision, finer detail, and greater intelligence. Free flap transplantation has undergone a conceptual shift from focusing solely on recipient site repair to also emphasizing donor-site protection, driving the development of free perforator flaps towards ultra-thin, chimeric, and functional designs, and also gradually opening the exploration into cutting-edge fields such as allogeneic or xenogeneic transplantation. Furthermore, artificial intelligence technology is increasingly integrated into the entire process of wound repair preoperative planning, intraoperative navigation, and postoperative evaluation, prompting clinical decision-making to shift from experience-dependent reliance to evidence-based support. This paper briefly discusses the microsurgical techniques and free perforator flaps for wound repair, aiming to offer theoretical support for their clinical application and optimization.
