[Results of myocutaneous flap for extensive skin defect in the external genitalia].
We reviewed 12 patients who underwent myocutaneous flap plasties to reconstruct the genital skin. The patients included 9 who underwent a radical excision of malignant tumor involving the genital, inguinal or sacral skin, 1 with an extensive radiation ulcer of the genitalia and 2 with an ulcerating cancer of the scrotum or groin. In the latter 2 patients the plasty was intended to cover an unresectable ulcerating cancer. A gracilis myocutaneous flap was used in 10 patients, and a tensor fascia lata myocutaneous flap in 2 patients. Postoperatively, partial or total necrosis of the skin of the flap developed in 8 patients. In 4 of these, infection complicated the necrosis. Although debridement, resuture or free skin transplantation was needed in these patients, wound healing was ultimately achieved in 10 patients who underwent radical excision of malignant tumor or radiation ulcer. In contrast, the intended coverage of an unresectable ulcerating cancer was unsuccessful in two other patients. No patients had motor disturbance after wound healing. However, one patient developed stricture of the urethra and vagina which had been opened through the flap, and another patient complained of gait disturbance and difficult defecation because of an swelling of the flap around the anus. Incision or excision was required to relieve the complaints in these 2 patients. These results indicate that a myocutaneous flap is useful to cover an extensive skin defect of the genitalia, but may be accompanied by postoperative complications particularly before wound healing. Appropriate management is necessary to achieve the intended reconstruction.
