Onco-reconstructive supermicrosurgery.

Supermicrosurgery is sophisticated microsurgical technique, which allows dissection and anastomosis of blood/lymphatic vessels and nerves with external diameter of 0.5 mm or smaller. With increasing attention to quality of life of cancer survivors, less invasive and functionally-better oncological reconstruction using supermicrosurgical techniques is warranted. Unlike conventional free flap reconstruction, supermicrosurgical free flaps can be elevated from anywhere using innominate vessels with diameter of 0.1 mm or larger, allowing patient-oriented least invasive reconstruction. Since lymphatic vessels can be anastomosed, lymphatic reconstruction is possible with supermicrosurgery, which plays an important role in management of cancer-related lymphedema. Supermicrosurgeons can harvest vascularized tissues such as skin, fat, fascia, tendon, ligament, bone, muscle, and nerve separately, and reconstruct complicated defects with three-dimensionally-inset multi-component tissue transfer.
