Purpose | Inverted nipple repair | Inverted nipple repair | Neo-nipple reconstruction | Neo-nipple reconstruction |
Main differences | Three diamond-shaped flaps to pass through tunnels under the nipple while the nipple was retracted, and the lactiferous ducts and fibrous tissue were transected (Figure 8(A)).
| The elevated dermal flaps are passed through the tunnels created and sutured to the adjacent deepithelialized dermal region. Design depends on twisting and locking principle (Figure 8(B)).
| It may be considered as one of the first attempts to reconstruct a neo-nipple. Elevation of three thin split thickness flaps based on a central undisturbed skin disk. The three flaps were bunched centrally creating an umbilicated nipple and leaving a deepithelialized zone that was allowed to heal as the areola (Figure 8(C)).
| · Mainly targets Neo-nipple reconstruction. · No dermal flaps tunneled · No twisting · Flaps separately depend on three peripheral bases not one central base (Figure 8(D)).
