Preliminary Application of a Novel Autologous Scrotal Dartos Flap Method for Enlargement of Penile Girth in Men with Small Penis Syndrome

Background: Augmentative phalloplasty is a controversial issue. A safe, stable, and efficient surgical method for penile girth enlargement (PGE) was not avaliable. This paper introduces a novel autologous scrotal flap-turning procedure “scrotal dartos flap method” for males with small penis syndrome (SPS) and addresses its efficacy and safety. Methods: A single‐centered, prospective study was conducted at the Zhongnan Hospital of Wuhan University, where 29 patients were treated with “scrotal dartos flap method”. The key procedure for this technique is fully turning the scrotal dartos flap to the loose plane just between the superficial penile fascia and Buck’s fascia to increase the circumference of the penis. Penile girth improvement and adverse events (AEs) were recorded. Results: Complete follow‐up data were collected for 27/29 (93.1%) of the patients. It yielded a 3.59 ± 0.80 cm (50.8%) girth improvement. This enlargement surpassed that of most previous published surgical procedures. Additionally, there were no serious AEs (such as penile fibrosis, flap infection, sclerosis, or removal) during the 6-month follow-up. Wound infection (n = 1), hematoma (n = 2), and folding (n = 1) were all slight. Conclusions: This novel autologous flap-turning procedure performed better than the majority of previously published PGE methods and was accompanied by only slight and acceptable AEs. “Scrotal dartos flap method” appears to be a viable method for the PGE treatment of SPS.
