Penile defect greatly decreases patient's quality of life. Construction or reconstruction of a penis (phalloplasty) is a complicated surgical procedure and there are several techniques to perform, among which, the radial forearm free flap is considered most advantageous. However, it is impossible to use radial forearm free flap in some cases, and the fat-cutaneous pedicle flaps in nearby area are also good alternative solutions. Objective: This study presents some characteristics of the inferior epigastric vessels and its application in phalloplasty using fat-cutaneous pedicle flaps. Subject and method: 26 inferior epigastric vessel specimens of 13 adult male reserved cadavers, and 3 penile defected patients with contraindication for using radial forearm free flap. Result: 100 percent cadavers have inferior epigastric vessels; the average distance from the origin of the pedicle to the midpoint of penile base is 90.4mm; the length of the pedicle from the origin to the position of arteries with 1 mm-diameter is 156mm; the average number of perforators is 5.4. In clinical application, 2/3 cases underwent phalloplasty using inferior epigastric perforator fat-cutaneous pedicle flaps had good ureteral function, but all 3 reconstructed penes were not in good shape due to thick fat layer of the flaps. Conclusion: The inferior epigastric vessels were constant, the length and the number of perforators of the pedicle appeared suitable for using in phalloplasty with abdominal fat-cutaneous pedicle flap. The reconstructed penes were not in good shape due to thick fat layer of the flaps and required additional reconstruction.
