Background: Nipple reconstruction is an important last step in the process of autologous or implant-based breast reconstruction. A multitude of techniques have been described, among others the S-flap. To prevent nipple retraction after surgery, we modified the originally described method by Cronin.
Methods: By adding an S-shaped incision line, the flap can be transposed with less tension and sutured on top of the new nipple along a curved line. Furthermore, two small triangular flaps were inserted at the base for reinforcement and reduced linear contraction. Assessment was completed by measuring nipple diameter and projection with a caliper.
Results: A total of 16 patients underwent the technique, of whom 11 could be followed after 3 and 6 months. Overall patient satisfaction with the aesthetic result was high, and we observed no infection or necrosis. Nipples were stable in size and shape at 6 months. Although reduction of 68% in projection and 31% in diameter was observed, the nipples remained pleasantly similar to the contralateral non-operated side.
Conclusions: The modified S-flap is a simple and reliable technique for moderate-sized nipple reconstruction. By providing more tissue at the base, size and projection remain stable and durable. Moreover, by a modified linear incision line at the base, tension and subsequent scar contraction is minimal.
