One-Stage Implant-Based Breast Reconstruction With Polyurethane-Coated Device: Standardized Assessment of Outcomes

Background Nipple-sparing mastectomies (NSMs) and implant-based breast reconstructions have evolved from 2-stage reconstructions with tissue expansion and implant exchange to direct-to-implant procedures. In this study, we tested safety and efficacy of polyurethane-based implants according to standard assessment tools.Objectives This study aimed to test safety and feasibility of polyurethane-coated implants with standardized assessment employing internationally acknowledged evaluation criteria.Methods Cases of NSMs followed by breast reconstruction in 1 stage with immediate prepectoral polyurethane-coated implant placement were retrospectively reviewed. Preoperative characteristics of the population have been collected. Adherence to quality assurance criteria of the Association of Breast Surgery-British Association of Plastic Reconstructive and Aesthetic Surgeons was verified. Complications were assessed with the Clavien Dindo classification, modified for the breast. Rippling, implant rotation, and malposition were also evaluated.Results Sixty-three consecutive patients underwent 74 NSMs and immediate breast reconstruction with micro polyurethane foam-coated anatomic implants. In 5 cases we had unplanned readmissions with return to the operating room under general anesthesia (6.7%) and implant loss within 3 months from breast reconstruction (5 implants, 6.7%). Postoperative complications according to Clavien Dindo were grade 1 in 6 cases (8.1%), grade 2 in 3 cases (4%), and 3b in 5 cases (6.7%).Conclusions Polyurethane-coated implants may prevent rotation and malposition and capsular contracture in the short term. Unplanned readmission rates and implant loss rates in the short term may be slightly higher.
