A Modified Bilateral Scrotal Flap for Penile Skin Defect Repair.

Skin shortages and scar contractures are common complications following penile trauma and tumor surgery, resulting in significant pain and erectile dysfunction. Currently, skin grafts and scrotal flaps are widely used to reconstruct skin shortages. However, various limitations still exist; for instance, the skin graft may cause severe scarring in patients, and the traditional scrotal flap usually requires a two-stage procedure due to the large skin defect. To treat the shortage of foreskin, a modified bilateral scrotal pedicled flap is used. In this procedure, flaps located on each side of the midline of the scrotum, which was pedicled from the anterior scrotal artery, are harvested. Subsequently, these bilateral scrotal flaps, like a butterfly, can successfully cover the foreskin defect. In this study, seven patients underwent this procedure, and satisfactory outcomes were obtained. Only two patients developed necrosis in some small areas of the flaps, which were recovered after wound care. Postoperative penile length significantly increased compared to the preoperative status in both flaccid and erectile states. We believe that modified bilateral scrotal flaps are a simple and effective solution to penile skin shortages and scar contractures.
