A new surgical procedure for phallic reconstruction: Istanbul flap.

A new surgical procedure is described for phallic reconstruction, which still remains a great challenge in reconstructive surgery. In this procedure, an osteocutaneous radial forearm flap is combined with a radial recurrent fasciocutaneous flap from the anterolateral aspect of the upper arm. While keeping a fasciovascular connection between them, both flaps are elevated as a combined free flap based on the radial artery. The forearm skin island is used solely to construct the outer skin cover of the phallic shaft, and the neourethra is created by using the radial recurrent flap. Over the past 4 years, this surgical procedure, termed the Istanbul flap, has been used successfully for complete phallic reconstruction in five patients. Although more clinical experience with this new technique is needed, it seems to be a useful alternative in phallic reconstruction. It remarkably minimizes the donor-site scar without sacrificing the length of the neopenis. In addition, this technique reduces the risk of a hairy urethra.
