Abstract:
Objective: To evaluate the effectiveness of pedicled skin flap of foreskin for phalloplasty and Sugita surgical method in the treatment of complete concealed penis. Methods: The clinical data of 46 children with complete concealed penis between January 2016 and January 2018 were analyzed retrospectively. Among which, 25 cases were treated with pedicled skin flap of foreskin for phalloplasty (group A) and 21 cases were treated with Sugita surgical method (group B) with an average age of 4.7 years (range, 2 years and 8 months to 11 years). At 3 months after operation, the concealed penis recovery was scored from three aspects of postoperative penis length (the difference of the penis length between at 3 months after operation and before operation), penis appearance, and skin appearance (the total score was 10). And the parents evaluation of satisfaction degree of penis exposure, penis appearance, and foreskin appearance after surgical correction was collected. Results: Eighteen cases (72.0%) in group A and 15 cases (71.4%) in group B were followed up with an average of 13 months (range, 3-36 months). The incisions healed well in both groups, and there was no flap dehiscence, infection, necrosis, and penile erectile dysfunction. The penile length of the two groups increased significantly at 3 months after operation ( P<0.05); there was no significant difference between the two groups in terms of penis length and increased length at 3 months after operation and score of increase penis length after operation ( P>0.05). No penile retraction occurred in the two groups. And there was no significant difference between the two groups in penis appearance score, but the penis appearance score, skin appearance score, and total score of group A were significantly better than those of group B ( P<0.05). At 3 months after operation, the satisfaction rate of penis exposure in group A and group B was 88.9% and 80.0%, respectively, with no significant difference ( χ2=0.50, P=0.48); the satisfaction rate of penis appearance was 72.2% and 53.3%, and the satisfaction rate of foreskin appearance was 94.4% and 53.3%, respectively, and the differences were significant ( χ2=5.13, P=0.03; χ2=7.53, P=0.01). Conclusion: Both surgical methods are suitable for correction of complete concealed penis, and the penile length gets a satisfactory recovery. However, the lymphedema of the prepuce after Sugita surgical method is serious, which can easily lead to poor appearance of the penis after operation. In general, the effectiveness of pedicled skin flap of foreskin for phalloplasty is better than that of the Sugita surgical method.
