Evolution of different forearm flap designs in phalloplasty.

Phalloplasty is one of the most complex procedures in plastic surgery. The criteria for an ideal neophallus include an aesthetic and erogenous phallus that allows for sexual intercourse, with a functional neo-urethra enabling standing urination. The free forearm flap has become the gold standard for phallic reconstruction. Various modifications have been made to improve vascularization and reduce urinary complications, such as fistulas and urethral stenosis. Each design has its advantages and disadvantages, with the goal of minimizing functional and aesthetic sequelae in the donor area while achieving the most satisfactory result in the recipient area. Over the years, several prominent surgeons have proposed different forearm flap designs, always with the aim of improving outcomes and patient satisfaction.
