The Free-style Gluteal Perforator Flap in the Thinning and Delay Process for Perineal Reconstruction After Necrotizing Fasciitis.

Perineal wounds present a special challenge for reconstructive surgeons. The vacuum-assisted closure device is useful as a temporizing measure or for wounds too large or contaminated for immediate reconstruction. Compared to traditional myocutaneous flaps, perforator flaps provide thinner fasciocutaneous flaps for perineal reconstruction with favorable results and fewer donor site morbidities. The upper and lower gluteal regions are rich in perforators, which allow for more versatile flap design according to the defect. The authors combined the principles of free-style perforator flaps, flap delay, and thinning of perforator flaps to restore perineal function and aesthetics. The procedure was undertaken in a 72-year-old female who was obese with the diagnosis of necrotizing fasciitis secondary to perineal abscess. After 3 months, the flap achieved adequate and durable reconstruction with acceptable aesthetic contour and patient satisfaction; there was no loss of function at donor sites. Clinical applications and technical refinements of freestyle pedicled perforator flaps can be extended to the perineal region. Because of its many advantages and its versatility, freestyle pedicled perforator flaps constitute a valued reconstructive option and, when indicated, an alternative to pedicled axial flaps or even free flaps, in addition to vacuum therapy, to simplify the reconstructive procedure.
