In the setting of secondary breast reconstruction by deep inferior epigastric artery perforator (DIEP) flap, the mastectomy skin is usually deepithelialized and buried under the reconstructed breast. In this study, by virtue of tube flap technique, we hypothesize that an amount of mastectomy skin could be transferred to the apex of reconstructed breast mound for nipple reconstruction. A total of 30 female postmastectomy patients were recruited between June 2012 and August 2015. A bipedicle DIEP flap was harvested and folded upward to reconstruct the breast. An inferiorly based mastectomy flap was raised and rolled into a tube. The free end of the flap was sutured to the reconstructed breast mound to allow revascularization. After serial stages, a sufficient tissue bulk from the mastectomy flap was transferred to the apex of the breast mound and remolded into a new nipple. Reconstructed breasts and nipples survived well postoperatively. The mean nipple projection was 9.2 ± 2.7 mm at the 1-year follow-up. In total 24 patients ranked the overall nipple and breast reconstruction to be very good or good. Based on DIEP flap breast reconstruction, the staged immediate nipple reconstruction with local mastectomy tube flap could maintain a long term residual projection with aesthetically acceptable outcomes.
