Lightweight Breast Implants in Augmentation-Mastopexy: A Retrospective Analysis of Clinical, Aesthetic, and Patient-Reported Outcomes

Abstract Background Augmentation-mastopexy is a complex procedure with high demands on soft tissue support and long-term aesthetic stability. Implant weight is a key biomechanical factor contributing to tissue stretching, inferior pole elongation, and secondary ptosis. Polytech B-Lite implants reduce implant mass preserving volume and shape, mitigating these challenges. Objectives This study evaluates clinical, aesthetic and patient-reported outcomes of lightweight B-Lite breast implants in augmentation-mastopexy, focusing on complication rates, aesthetic stability, and patient satisfaction. Methods A retrospective observational study included 73 female patients undergoing primary augmentation-mastopexy with prepectoral B-Lite implants between January 2020 and December 2024. Inclusion criteria comprised ptosis ≥2 cm, BMI ≤30, and no prior breast surgery. Patients were followed for a mean of 26.4 ± 9.1 months. Outcomes included postoperative complications, standardized photographic assessment of breast, and BREAST-Q scores. Results Mean implant volume was 285 ± 65 cc (range, 180–450 cc). Overall complication rate was 9.0%, with early minor wound dehiscence in 4.1% and seroma in 2.7%. No hematomas or implant losses occurred. Late complications included capsular contracture (Baker >2) in 2.7% and secondary ptosis in 4.1%. Revision surgery was required in 4.1% of cases, for minor aesthetic refinements. Standardized photography demonstrated stable upper-pole fullness and nipple–areola complex positioning. BREAST-Q scores demonstrated high levels of patient-reported satisfaction consistent with previously published augmentation-mastopexy studies. Conclusions In this retrospective cohort, lightweight breast implants used in augmentation-mastopexy were associated with low complication and revision rates, favorable aesthetic outcomes, and high patient satisfaction. Therefore reduction of implant mass may contribute to improved structural durability and more sustainable results. Further prospective comparative studies are needed.
