Background To describe our scrotal bridge flap technique in reconstructive surgery for extensive penile paraffinoma, a debilitating late complication of penile subcutaneous foreign material injection intended to achieve penile augmentation. Case presentation We reviewed the medical records of 10 patients who underwent reconstructive surgery with the scrotal bridge flap technique for penile paraffinoma at our center between 2016 and 2019. Complete excision of fibrotic tissue and the overlying skin was performed, and penile resurfacing was achieved by mobilizing the scrotal skin superiorly to wrap around the penile shaft, leaving a skin bridge at the median raphe. All 10 patients successfully underwent scrotal bridge flap penile reconstruction with satisfying results. The mean operation duration was 286.1 min (range 213–363 min). No immediate major complications were observed in any of the patients, and no patients required revision surgery. Conclusion The scrotal bridge flap technique is a reliable method for reconstructive surgery after the excision of penile paraffinoma.
