Gluteal fold V-Y advancement flap for vulvar and vaginal reconstruction: a new flap

Soft-tissue reconstruction following vulvar cancer resection is a difficult challenge because of the functional, locational, and cosmetic importance of this region. Although numerous flaps have been designed for vulvar reconstruction, each has its disadvantages.

The authors introduce the gluteal fold fasciocutaneous V-Y advancement flap for vulvovaginoperineal reconstruction after vulva cancer resection. This flap is supplied by underlying fascial plexus derived from perforators of the internal pudendal artery and musculocutaneous perforators of underlying muscle. The sensory supply of this flap comes from the posterior cutaneous nerve of the thigh and the pudendal nerve. An axis of V-shaped triangular flap is aligned to the gluteal fold. A total of 17 flaps were performed in nine patients.

All flaps survived completely, with no complications except for small perineal wound disruption in three patients.

This flap is thin, reliable, sensate, easy to perform, and has matched local skin quality and concealed donor-site scar on the gluteal fold. In addition, it can cover large vulvovaginal defects because it can be advanced farther as a result of the character of the gluteal fold area. In our experience, the gluteal fold fasciocutaneous V-Y advancement flap has proven very useful for vulvar reconstruction, especially at the point of donor-site scar, flap thickness, and degree of flap advancement.
