Pedicle perforator flaps for vulvar reconstruction--new generation of less invasive vulvar reconstruction with favorable results.

ABSTRACT

OBJECTIVES: Vulvar reconstruction after cancer surgery remains challenging. Pedicle perforator flaps are believed to be a less invasive option with better cosmesis. METHODS: A retrospective review identified 27 flaps in 16 patients who underwent vulvar reconstruction after cancer surgery using island pedicled perforator flaps. Their average age was 55.7±17.8 years (Range 22-85). The average BMI was 23.5±4.0 (range 18.8-28.5). Five of the 16 patients underwent unilateral vulvar reconstruction, and 11 of them underwent bilateral vulvar-perineal reconstructions. The perforator flaps included deep femoral (profunda) artery perforator (DFAP or PAP) flaps (n=11), medial circumflex femoral perforator (MCFAP) flaps (n=8), external pudendal artery perforator (EPAP) flaps (n=2), medial thigh free style perforator flaps (n=2), and internal pudendal artery perforator flaps (n=4). RESULTS: All flaps survived with a 100% success rate. Three patients developed small wounds that required debridement and closure after the reconstruction. All donor sites were closed primarily. One patient developed temporary peroneal nerve palsy. During follow-up, none of the patients presented with donor site morbidities. All of the patients were satisfied with the cosmetic and functional results, except that one patient underwent a flap debulking procedure three months after surgery. CONCLUSIONS: Compared to traditional myocutaneous flaps, perforator flaps provide thinner fasciocutaneous flaps for vulvar reconstruction with favorable reconstruction results and fewer donor site morbidities. The medial or inner thigh is a region that is rich in perforators, which allow for more versatile flap design according to the defect. Furthermore, most of the donor site can be closed primarily without complications.
