Anatomical and functional outcome after bilateral scrotal flap in penile reconstruction

Background: Injection of alloplastic material underneath the penile skin for penile augmentation causes many complications such as inflammation, infection, ulceration, and pain during sexual activity. One of the treatments for complications after these penile augmentation procedures is surgical excision of the foreign body granuloma followed by penile skin coverage with bilateral scrotal flaps. There are no prior prospective studies published about anatomical and functional outcomes. Objective: To study the anatomical and functional outcome of one-stage bilateral scrotal flap reconstruction in patients after surgical removal of paraffinoma from penile shafts. Methods: Patients who suffered from complications of penile foreign body granuloma were treated by surgical excision and reconstruction with bilateral scrotal flaps. The penile lengths and circumferences when flaccid and erect were recorded preoperatively and postoperatively. The patients were interviewed using questionnaires and satisfaction scored to determine their sexual experiences were recorded before and after surgery. Results: Thirteen patients were enrolled in this study. The mean follow-up time was 23.5 (11.5-40.5) weeks. The Mean erectile length and the maximal circumference were 11.8 (9-15) cm, 14.5 (11.5-17) cm preoperatively, and 11.7 (10-14) cm, 11.8 (10-13) cm postoperatively. Satisfaction scores of sexual activity is 6.84 (0-9) preoperatively, and 8.38 (5-10) postoperatively. Conclusion: One-stage bilateral scrotal flap coverage is a good option for penile skin reconstruction. This technique can achieve satisfactory results both anatomically and functionally.
