The anterolateral thigh (ALT) flap is a viable and reliable option for phalloplasty. The primary advantages of the ALT flap remain an inconspicuous donor site and flexibility in phallus length. The disadvantages of the ALT flap are a higher incidence of both flap and urethral complications compared with a radial forearm phalloplasty. Although the ALT phalloplasty can achieve the primary goals of standing micturition, penetrative intercourse, and an aesthetic phallus, multiple stages and revisions are often necessary. Careful patient selection is paramount in attaining acceptable results with the ALT phalloplasty technique.
