[Definition of Supermicrosurgery] Supermicrosurgery is a sophisticated microsurgical techniques dealing with 0.5 mm or smaller vessels. Unlike conventional microsurgery, forceps cannot be inserted into a supermicro-vessel, and a surgeon has to anastomose based on supermicro-needle-tip sensation.

[Training for Supermicrosurgery] Rat epigastric artery (0.3-0.5 mm) is favorable for supermicrosurgical anastomosis training. Mouse epigastric artery (0.15-0.2 mm) can be used for higher-level training. Chicken wing/thigh vessels (0.2-1.0 mm) are suitable for daily training.

[Applications of Supermicrosurgery] Supermicrosurgery allows various sophisticated reconstructions as follows;
Lymphatic Anastomosis: Collecting lymph vessels can be anastomosed, which allows treatments of lympho-rrhea/-cyst and lymphedema, Lymphaticovenous anastomosis and lymphaticolymphatic anastomosis are applied.
Small Tissue Replantation: Fingertip replantation can be done with high success rate.
Short-pedicle Free Flap: Flap based on a true perforator or distal perforator can be safely transferred with perforator-to-perforator anastomosis.
Day Microsurgery: Free flap reconstruction can be done as a day surgery without hospitalization. Use of short-pedicle flap and local anesthesia are keys.
Multiple Free Flaps: Short-pedicle free flap transfer requires significantly shorter dissection/preparation time, allowing simultaneous multiple flap transfers.
Chimeric SCIP Flap: Supermicrosurgical dissection allows three-dimensional multi-component SCIP flap elevation and transfer, allowing anatomical/physiological reconstruction of complex defects; superficial branch for skin, fat, lymph node/vessel, fascia; deep branch for skin, fat, fascia, muscle (sartorius), nerve (GFN, LFCN), bone (iliac).
