Comparison of Polytech MESMO and Motiva Ergonomix Breast Implants With a Focus on Displacement Issues: A Single Surgeon's Experience in 329 Patients.

BACKGROUND: Nanotextured breast implants (classified as smooth implants by the latest ISO 14607:2018) have been described as they may reduce major textured implant-related complications such as capsular contracture and breast implant-associated anaplastic large cell lymphoma. On the other hand, micro-textured breast implants benefit from an optimal safety profile based on a much larger body of literature.

OBJECTIVES: To directly compare the incidence of complications between Motiva Ergonomix (Establishment Labs, Alajuela, Costa Rica) and Polytech MESMO (Polytech Health & Aesthetics GmbH, Dieburg, Germany) breast implants, especially regarding the displacement issues that might arise after breast augmentation.

METHODS: Consecutive patients previously operated by the same surgeon with Motiva Ergonomix and Polytech MESMO implants were included in this study. They were divided into two groups according to the type of implant. The onset of complications was assessed through survival analysis.

RESULTS: Data were collected from 329 patients, 185 (56.2%) carrying Polytech MESMO, and 144 (43.8%) Motiva Ergonomix implants. The median follow-up was 8 months for both groups. Of the 42 women (12.8%) who experienced at least one complication, 26 belonged to the Motiva Ergonomix subgroup (p = 0.013). The most represented complications during this period resulted from displacement issues, with a clear prevalence of bottoming out in the Motiva Ergonomix cohort: 15 cases versus 0 cases in the Polytech MESMO cohort (p < 0.001). For 7 patients, a reoperation was required, more frequently for patients with Motiva Ergonomix implants (4.2% versus 0.5%; p = 0.046).

CONCLUSIONS: Polytech MESMO devices provided a more favorable outcome. Motiva Ergonomix devices revealed a concerning incidence of displacement issues during the first post-surgery years, with no advantage over other major complications.
