Clinical application of expanded free flaps based on primary or secondary vascularization.
Prefabricated free flaps using an expansion technique were used for four reconstructive cases, including two leg reconstructions and two facial reconstructions. In this series, the prefabricated free flaps created by using the expander were classified into two types: the expanded flap based on the conventional vascular pedicle, which is called the expanded flap with primary vascularization; and the expanded flap based on the vascular pedicle in the carrier, which is called the expanded flap with secondary vascularization. The expanded flap with primary vascularization that is created in the trunk has a good indication for leg reconstruction, because it provides an wide and thin flap with minimal donor site morbidity. The expanded flap with secondary vascularization created in the pectoral region has a good indication for facial reconstruction, because it provides good color and texture matches. Although there are some disadvantages in the tissue expansion technique, the prefabricated free flaps using the expander are very effective in facial and leg reconstruction.
