Background: Phalloplasty is a crucial part of female-to-male genital gender-affirming surgery, however, up to date, there is still no standardized phalloplasty technique.

Aim: To evaluate the outcome of a single-center series of phalloplasties using the free radial forearm flap variations by Chang and Hwang vs by Gottlieb and Levine on a similar number of transgender patients.

Methods: Between 2018 and 2020, 45 female to male transgender patients underwent phalloplasty using a neuro-microvascular free radial forearm flap in our department.
