Scrotal Reconstruction Using a Free Ulnar Forearm Flap: A Case Report.

Scrotal defects requiring reconstruction may occur after trauma, cancer, or infection. To maintain good testicular function, the ideal scrotal temperature should be slightly lower than the abdominal temperature. However, large local flaps that are enough to cover the testes cannot be used in all patients. A 74-year-old man presented with scrotal and perineal tissue defects after undergoing debridement for Fournier's gangrene due to rectal carcinoma-induced perforation. The scrotal skin defect was reconstructed using a 22 × 10-cm-free ulnar forearm flap. The postoperative course was uneventful, and at the 14-month follow-up examination, the scrotal skin was found to be thin and pliable. Moreover, the donor site on the left forearm was in an acceptable state and no hand dysfunction due to contracture was observed. Based on our observations, we recommend that the free ulnar forearm flap might be an effective option for scrotal reconstruction, causing little donor site morbidity.
