Background:
Multi-lobed perforator flap was one of popular approaches for one-stage reconstruction of complex soft tissue defects because of its minimal donor-site morbidity. However, the area of skin island that can be harvested on the donor site is limited on the angiosome distribution, Moreover, large defects require more than the conventional skin island provided by a traditional multi-lobed perforator flap. For further extended skin paddles, this study presented a novel design of waveform-arranged skin paddles to elevated a modified multi-lobed perforator flap for the reconstruction of complex soft tissue defects in the extremities.
Methods:
From March of 2015 to March of 2020, fifteen patients underwent complex soft tissue defects reconstruction with waveform-arranged multi-lobed perforator flaps. According the size, shape and localization of the defects, two strategies were performed to design this modified multi-lobed flap.
Results:
A total of fifteen waveform-arranged multi-lobed perforator flaps were successfully harvested to reconstruct complex soft tissue defects of the extremities. Among of them, Waveform-arranged dual skin paddles perforator flap were performed in eleven cases, and the waveform-arranged tripaddle perforator flaps were used in four cases. All the flaps survived and no flap related complication was observed postoperatively. The donor sites were closed directly in all cases. The mean follow-up time was 15.6 months. Most of the cases showed satisfactory contour.
Conclusion:
The waveform design of multi-lobed perforator flap was an alternative approach for reconstruction of complex soft tissue defects; it can maximize the harvested skin area of the donor site to provide extended skin island.
