Pre-expanded Paraumbilical Perforator Flap.

The paraumbilical perforator flap is the first and the most famous perforator flap. Pre-expansion increases the flap dimension and reduces the flap thickness and donor site morbidities, making the paraumbilical perforator flap a more effective option for upper extremity reconstruction. Pre-expanded pedicled paraumbilical perforator flaps can achieve excellent function and aesthetic outcomes in patients with extensive scar contracture and giant melanocytic nevi in the upper extremity. Although this technique requires multiple procures, each operation is relatively simple and has a low complication rate, when properly planned and performed.
