Radial Forearm.

The radial forearm free flap phalloplasty provides a thin, potentially sensate, minimally hair-bearing cutaneous flap. Since its initial description, several modifications of the technique have emerged. The earliest dimensions described needed to be increased because of the increase amount of subcutaneous fat in the Western population. Incorporating a centrally placed neo-urethra with a distal extension that gets folded over to create a semblance of a neoglans eliminates the distal/meatal stenosis. Performing a urethral extension at a preliminary surgery and extending the neourethra proximally has improved the position of the neophallus and minimized proximal urethral strictures and fistulas in transgender men.
