At present, for patients with short penis, the surgical method of using decellularized allogeneic dermal matrix patch to thicken the corpus cavernosum and lengthen the penis at the same time is welcomed by patients because it has the advantage of lengthening and thickening the penis at the same time in one operation, and more and more relevant hospitals try to carry out this kind of surgery, but due to the lack of in-depth understanding of the anatomical structure of the penis by many surgeons, the blood supply of the penile skin is injured during surgery, resulting in However, due to the lack of in-depth understanding of the anatomy of the penis by many surgeons, the blood supply of the penile skin is injured during surgery, resulting in serious complications of penile skin necrosis. Based on my experience of seeing and successfully managing many such cases around the world, the anterior scrotal artery flap is a good repair tool with the following advantages: the texture, color, and thickness of the flap match the penile skin tissue, resulting in a good appearance after repair; the flap is easy to retrieve and can be easily rotated to cover the missing surface; the donor scar is small and very concealed; and the flap has good extensibility and does not significantly pull the penis during erection, causing it to shift laterally. Nevertheless, based on a thorough understanding of the blood supply to the penile skin, the design of a safe surgical method (such as the biplanar method I am currently using), together with a delicate surgical operation, it is entirely possible to avoid such complications.
