What this trial studies

This study evaluates the safety and performance of Silimed® brand smooth surface breast implants in women undergoing primary and secondary breast augmentation. It will follow participants for 10 years to assess both known and unexpected adverse events through patient reports. Additionally, the study will measure satisfaction and quality of life outcomes post-implantation. The observational nature of the study allows for real-world data collection on the implants' long-term effects.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with a complaint of hypomastia and an indication for breast augmentation using silicone implants.

Not a fit: Patients who have had complications requiring breast implant replacement or those with active infections or untreated neoplasia will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety and satisfaction associated with Silimed® breast implants, guiding future patients in their augmentation decisions.

How similar studies have performed: While there have been studies on breast implants, this specific analysis of Silimed® smooth surface implants is novel and focuses on long-term outcomes.
