Redefining Reconstruction: Technological Innovations in Microsurgical Breast Reconstruction.

Background: Microsurgical breast reconstruction is advancing rapidly with the integration of innovative technologies that enhance surgical precision, safety, and outcomes. This narrative review highlights recent developments across four key phases: flap planning, flap harvest, microvascular anastomosis, and flap monitoring. Methods: To identify the most updated and relevant data, all content on «Aesthetic and Reconstructive Breast Surgery Network» (ARBS Network, Copyright 2025 Mark Allen Group, United Kingdom) was screened regarding new technology. The contributions were grouped into one of four key phases. More references related to the content viewed were then searched on the electronic database MEDLINE (Bethesda, MD: U.S. National Library of Medicine). Results: 24 contributions regarding new technology were identified on ARBS Network. Of these, 17 were relevant for this paper. Preoperative tools such as CT angiography and AI-based perforator mapping optimize surgical planning and execution. Robotic-assisted or endoscopic techniques for deep inferior epigastric perforator (DIEP) flap harvest enable minimally invasive dissection with reduced donor-site morbidity and improved muscle preservation. Robotic microsurgery, particularly with the MUSA and Symani® Surgical System, allows for precise, tremor-free suturing of submillimeter vessels. Indocyanine green (ICG) angiography remains the gold standard for intraoperative perfusion evaluation. Postoperative flap surveillance is crucial for detecting vascular compromise early. Devices such as the Cook-Swartz Doppler probe and flow couplers offer continuous monitoring. Wireless oximetry systems like ViOptix® provide non-invasive, real-time perfusion data and support remote monitoring. Conclusions: Collectively, these innovations are transforming microsurgical breast reconstruction by increasing efficiency, consistency, and outcomes.
