A technique of vaginal reconstruction using bilateral, perineal-thigh flaps with subcutaneous pedicle is described. In this procedure, the flaps were raised bilaterally and introduced into an artificial space between the urinary bladder and rectum. The blood supply for the flaps flows from the perineal artery through anastomotic branches to the external pudendal artery. The authors used the technique on four patients, and all the flaps survived entirely. There was no complication. According to a more than two-year follow-up survey, the reconstructed vaginas are expansible and contract little. No stent is needed. There is good sensitivity in the wall of the artificial vagina because sensory nerves run through the flaps.
