Background
Various operative methods exist for nipple reconstruction. Selection of an appropriate skin flap and core strut material is imperative in achieving a satisfactory outcome in nipple reconstruction. Long-term maintenance of nipple projection requires further investigation by surgeons. We propose a new technique that uses a semilunar flap and omega-shaped acellular dermal matrix (ADM).
Methods
Total 53 nipples were reconstructed by this method. An omega-shaped ADM strut was inserted into the barrel made by a semilunar flap. The footplates of omega-shaped ADM struts were spread out under the subcutaneous tissue of the donor site of the semilunar flap to support the dome of the omega strut.
Results
The mean maintenance rate of nipple projection was 95.12 ± 6.30% at 3 weeks, 80.60 ± 8.93% at 3 months, and 71.70 ± 8.67% at 6 months postoperatively when compared to the projection observed in the immediate postoperative period. Thirty-five patients (66.0%) showed a maintenance rate over 70% at 6 months post operation, with most patients (94.3%) demonstrating a maintenance rate greater than 60%.
Conclusions
Our study with the omega-shaped ADM strut showed superior maintenance rates of projection when compared to other studies on that used AlloDerm® as a core strut for nipple reconstruction. Omega-shaped struts, when made with cross-linked thick ADM, supported the skin flap quite well. We propose that our method combining the semilunar flap with an omega-shaped ADM may be a good option for nipple reconstruction.
