Phalloplasty is indicated in various conditions of penile loss or absence. There are numerous techniques for phalloplasty including the pedicle and free flaps with the ultimate goal of micturition in standing position, attaining adequate size, aesthesis and sensations for sexual intercourse. Radial forearm phalloplasty is the gold standard flap to achieve above results but gives a very bad scar on the forearm. We present a technique of using prefabricated thigh flap to reduce the morbidity of donor area. The descending branch of lateral circumflex femoral pedicle was placed in a subcutaneous plane over tissue expander. After attaining an adequate size of flap with tissue expansion, it was delayed 3 weeks before phalloplasty. Prefabricated flap was thin and of large size replicating the radial forearm flap used for phalloplasty. Whole forearm defect was covered with the thigh flap, and the thigh could be closed primarily. This new technique of using prefabricated thigh flap has significantly reduced the donor site morbidity both aesthetically and functionally without the use of skin grafting in the whole procedure.
