The Application of Supermicrosurgery in Lower Extremity Reconstruction and Future Implications

Supermicrosurgery is defined as microsurgical work performed on vessels smaller than 0.8 mm in diameter. This advancement enables surgical applications at finer scales, including the treatment of lymphatic disorders, minimally invasive reconstructions, small-part replantations, and perforator-to-perforator anastomoses. To facilitate these procedures, there has been significant development in ultrafine surgical instruments, microsutures, enhanced imaging and diagnostic technologies, robotic microsurgery platforms, and high-magnification microscopes or exoscopes. Supermicrosurgery represents more than just a refinement of microsurgical technique-it marks the emergence of a new field that deepens our understanding of anatomy and physiology at the microvascular level and innovative approaches to solving challenges.
