Objective: To analyze the causes of skin necrosis after penis lengthening surgery and corresponding treatment measures, and observe the clinical effect of free skin graft repair in the treatment of penile skin defects.
Methods: We retrospectively analyzed the clinical data on 12 cases of extensive penile skin necrosis and defect after penis lengthening surgery performed in our department from January 2017 to January 2022. The patients underwent free skin graft repair with medium- or full-thickness skin grafts from the thigh after wound preparation.
Results: The skin grafts survived well in all the 12 patients and the incisions healed in the first stage without any complications. At 6 months after surgery, skin sensation was mostly recovered in the area of penis skin grafting, no obvious skin ulceration or edema was observed, and the appearance of the penis was satisfactory. The IIEF-5 scores, Erectile Hardness Scale (EHS) scores, and the results of penile hardness tests of the patients all indicated normal erectile function.
Conclusion: Free skin graft repair with autologous medium- or full-thickness skin grafts is a safe and effective surgical option for extensive penile skin necrosis after penis lengthening surgery.
