Usefulness of Rapiplug in nipple reconstruction to improve nipple projection

The final stage of breast reconstruction after mastectomy for breast cancer is nipple reconstruction. However, a consistent and reliable method resulting in the most ideal aesthetic results has yet to be clarified. This study analysed the long-term outcomes of nipple reconstruction using Rapiplug.

Forty-one patients who underwent immediate breast reconstruction after mastectomy between January 2014 and February 2017 were enrolled. Nipple reconstruction was performed with C-V flap and Hammond flap, and hat-shaped Rapiplug was implanted at the flap core. Nipple projection and width were measured and nipple reduction rates were calculated immediately after and at 3, 6, and 12 months after surgery. Patient satisfaction was surveyed at the 12-month follow-up and compared with patient characteristics and other variables.

Forty-one nipple reconstructions were performed in 41 patients. Most post-operative adverse events were resolved with conservative management, and revision was performed in only one case. The mean nipple projections were 8.9 ± 1.8, 7 ± 1.8, 5.6 ± 1.6 and 4.9 ± 1.6 mm immediately, and 3, 6 and 12 months after surgery, respectively, and the mean reduction rate of nipple size with reference to the size immediately after surgery was 22.2%, 37.2% and 44.7% at 3, 6 and 12 months after surgery, respectively. Patient satisfaction was 82.9% in overall outcome, and 85.3% of projection was good or excellent.

Rapiplug can improve the long-term preservation of nipple projection after nipple reconstruction and is considered to be consistent and reliable with good aesthetic outcomes and no severe complications.
