The problems of foreign body injection such as vaseline, paraffine, mineral oil for penile augmentation done by illegal medical practitioners are tissue inflammation, necrosis, granuloma formation, deformity and erectile dysfunction. The treatment of these complication are composed of foreign body removal and resurfacing of denuded penis. Many resurfacing procedures are introduced such as split thickness skin graft, flap-to-graft conversion method, scrotal flap, groin flap and free flap. Skin graft is the simplest method with minimal donor site morbidity, but there are some complications like scar contracture, hypertrophic scar and difficulty of erection. Thick split thickness skin graft can prevent these complications. We measured the length, circumference and surveyed erectile function with International Index of Erectile Function(IIEF) after long-term follow up. Increase in mean length and circumference at erection are 43% and 36%, respectively, compared to resting, and the survey with IIEF had a better result than that of normal control group. We found preserved erectile function without scar contracture and hypertrophic scar. Thick split thickness skin graft is the good method for treatment of penile vaselinoma with simplicity, minor donor site morbidity and preservation of erectile function.
