Ergonomic Implants: A Single Centre Experience in Post-Mastectomy Breast Reconstruction

Background and Objectives: Implant-based breast reconstruction is nowadays the most commonly used reconstructive technique and offers a safe and relatively simple surgical approach. Textured, anatomically shaped implants have been the primary option for women undergoing breast reconstruction for decades. However, anatomically shaped implants are form-stable devices, providing firmness and rigidity, and can cause malrotation, requiring revision surgery. Ergonomic round silicone gel implants began to gain popularity due to the capacity to adapt to gravity and the patient's position, providing a natural, "anatomical" appearance in an upright position. The objective of this study was to describe our two-year experience with Motiva Ergonomix Round Silksurface™ implants and to evaluate their safety and efficacy for immediate and delayed breast reconstruction procedures. Materials and Methods: An observational retrospective study was conducted on a population of patients undergoing mastectomy for breast cancer and immediate or delayed reconstruction with Motiva Ergonomix Round Silksurface™ implants. We enrolled 61 patients from December 2023 to December 2025: a total of 87 ergonomic prostheses were implanted. Results: The average implant volume was 269 ± 105 (105-510) cc. One surgical infection occurred (1.1%); three persistent seromas (3.4%); and two cases of rippling (2.3%). Only one CTCAE G3 complication was recorded, a grade IV Baker capsular contraction (1.1%). The BREAST-Q results after surgery showed a high rate of patient satisfaction. Conclusions: Ergonomic round implants with a nano-textured surface were developed to give a natural breast appearance following mastectomy, as well as to prevent rotation, one of the complications that can affect anatomical implants. Our data have demonstrated low complication rates and high patient satisfaction. These results encourage us to expand our experience with these ergonomic, round, nano-textured implants and seriously consider them as an increasingly important device in breast reconstruction after mastectomy to be placed alongside more well-known anatomical implants.
