A Novel Perforator-Based Flap for Reconstruction of Post-Burn Groin Contracture

The contractures were released up to the healthy subcutaneous fat. This created wide defects in both the groins. The right side was addressed first. Doppler examination revealed a number of perforators in the upper third of medial thigh. A 12 cm x 6 cm flap was drawn on the medial thigh based on a dominant perforator about 5 cm below the inguinal ligament (Figure 2). The lateral margin of the flap was incised first and the gracilis identified. The flap was dissected medially in the subfascial plane till the medial border of gracilis was reached. Here a vertical row of perforators were identified. The medial margin of the flap was then incised and dissection proceeded up to the aforesaid perforators. The flap was based on a single perforator located about 5 cm below the pubic tubercle, and the rest of the perforators were legated (Figure 3). The flap was rotated into the defect and the donor site closed primarily. A similar procedure was adopted to resurface the left groin defect, where the dimensions of the flap were 15 cm x 8 cm (Figure 4).
