Abstract
Background
Nanotextured breast implants (classified as smooth implants by the latest ISO 14607:2018) have been described as possibly reducing major textured implant-related complications such as capsular contracture and breast implant–associated anaplastic large cell lymphoma. On the other hand, microtextured breast implants benefit from an optimal safety profile based on a much larger body of literature.
Objectives
The aim of this study was to directly compare the incidence of complications between Motiva Ergonomix (Establishment Labs Holdings, Inc., 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 who previously underwent surgery by the same physician for placement of Motiva Ergonomix and POLYTECH MESMO implants were included in this study. They were divided into 2 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%) with POLYTECH MESMO and 144 (43.8%) with 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 = .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 vs 0 cases in the POLYTECH MESMO cohort (P < .001). For 7 patients, a reoperation was required, more frequently for patients with Motiva Ergonomix implants (4.2% vs 0.5%; P = .046).
Conclusions
POLYTECH MESMO devices provided a more favorable outcome. Motiva Ergonomix devices revealed a concerning incidence of displacement issues during the first postsurgery years, with no advantage over other major complications.
