Staged Immediate Nipple Reconstruction With Tube Flap in Immediate Deep Inferior Epigastric Artery Perforator Flap...

In the setting of immediate breast reconstruction by deep inferior epigastric artery perforator (DIEP) flap, the excessive DIEP flap skin is de-epithelialized and then buried under the mastectomy skin. In this study, by virtue of tube flap technique, we hypothesize that the skin supposed to be abandoned could be transferred to the apex of reconstructed breast mound for nipple reconstruction.

A total of 60 female patients were recruited between January 2019 and December 2020. All these patients underwent mastectomy including nipple-areola complex and immediate DIEP flap breast reconstruction. A ladder-shaped pedicled flap was raised from the DIEP flap and rolled into a tube. The free end of tube flap was inset into the future nipple position of the reconstructed breast mound 1 week later. After revascularization for 1 month, we divided the previous pedicle and used the tube on the apex of the breast mound to recreate a new nipple.

All reconstructed breasts and nipples survived well postoperatively. The average nipple projection was 12.5 ± 2.0 mm immediately after the surgery, which gradually decreased to 9.4 ± 1.5 mm at 1-year follow-up, with the projection loss from the initial measurement as 24.9% ± 1.8%. In total, 51 patients considered the overall impression of breast and nipple reconstruction to be very good or good.

We provided an ideal technique that could improve the maintenance of reconstructed nipple projection and have aesthetically acceptable outcomes, without DIEP flap tissue loss, breast mound distortion, or additional scars.
