  • The Natrelle 150 offers the advantage of single-stage reconstruction. However, there is lack of published data on its long term outcomes, which does not allow for definitive conclusions as to whether it truly meets its design objective of a lasting single stage breast reconstruction. This is a retrospective review of all Natrelle 150 reconstructions by a single surgeon over 5 years. A total of 143 procedures were performed in 125 patients with a mean follow-up of 33 months (range, 3-65 months). Most (120, 84%) received the implant after oncological mastectomies, 22 (15%) after risk-reducing mastectomies, and 1 (0.8%) for hypoplasia. Fifty-one (35.7%) implants were explanted an average of 12.9 months after implantation. A Kaplan-Meier survival analysis demonstrates an explantation rate of 25% by 11 months. Explantation was more likely after subpectoral placement compared to reconstructions in combination with latissimus dorsi flaps (P<0.05). Risk-reducing reconstructions were also more likely to undergo explantation (P<0.05) compared to reconstructions for oncological reasons. Our data suggest that this prosthesis is only successful as a 1-stage procedure in certain patients, and has led to more careful patient selection and counseling.
