An Analysis of Adverse Events and Satisfaction Outcomes of Women Who Underwent Primary and Secondary Breast Augmentation Using Silimed® Breast Implants With Smooth Surface

The study investigates the safety and performance of Silimed® brand smooth surface breast implants in women born with indication for primary and secondary (revision) augmentation to be followed up for 10 years. The safety of the smooth-surfaced Silimed® implant will be evaluated by estimating known and unexpected short-term and long-term risk/adverse event rates through patient reports of adverse events after implantation. The performance of using Silimed® brand smooth surface breast implants will be evaluated by evaluating satisfaction and quality of life after implantation.

An Analysis of Adverse Events and Satisfaction Outcomes of Women Who Underwent Primary and Secondary Breast Augmentation Using Silimed® Breast Implants

The study investigates the safety and performance of Silimed® silicone gel breast implants with a textured surface and Silimed® silicone gel breast implants with polyurethane coated surface. Female patients who underwent primary or secondary breast augmentation using Silimed® breast implants will be followed-up through 10 years. The safety of each type of Silimed® breast implant is going to be assessed by estimating the known and unexpected short- and long-term risk / adverse event rates. The performance of each type of Silimed® breast implant is going to be assesses by estimating the satisfaction and quality of life after implantation.

Split Chest Breast Neurotization

Several members of the scientific community have suggested that breast neurotization can help return nipple sensation to patients undergoing implant-based breast reconstruction. There has been no randomized controlled study assessing the validity of these claims. The goal of this study is to evaluate if performing breast neurotization can help restore or improve return of nipple sensation to patients undergoing implant-based breast reconstruction. This will be a single-blinded, randomized controlled trial where patients undergoing bilateral reconstruction will serve as their own controls by receiving an intervention on one breast but not the other breast.

Molecular Mechanisms Associated With Breast Implant Complications

Bacterial biofilms cause implant failures, chronic inflammation, and immune polarization. The study investigates the possible role of bacterial biofilm as a factor in the etiology of Breast Implant Illness. Three patient cohorts will be studied (A) Subjects with breast implant with BII manifestations (B) Subjects with breast implants without BII manifestations (C) Subjects without breast implants who underwent breast surgery procedure. Blood, surgically discarded tissue, implants, and associated capsules will be collected through this protocol.

Seroma of the Mammary Gland

The study is designed as international, prospective, minimal interventional study in cooperation with EUBREAST e.V. (European Breast Cancer Research Association of Surgical Trialists). Furthermore, it is planned to initiate a registry for postoperative breast seromas.

Delayed-immediate Versus Delayed Breast Reconstruction in Breast Cancer Patients With Mastectomy and Radiation Therapy

In breast cancer patients treated by mastectomy and adjuvant post-mastectomy radiation therapy (PMRT) reconstruction is often delayed until 6 - 12 month after completion of chemotherapy and PMRT, due to high risk of complication. In this trial the safety of the delayed-immediate reconstruction method is tested, where a skin sparing mastectomy and reconstruction with silicone implant is performed at primary surgery to save the native skin for the final delayed reconstruction.

Characterization of Capsule Inflammation in Patients Exposed to Silicone Breast Implants

The use of breast implants, both in cosmetic and restorative surgery, is common. It is a device consisting of a silicone elastomer envelope and the container of which may be silicone gel or saline. They can be texturing carriers (roughness) on the surface of their envelope. If silicone is considered inert and biocompatible, several phenomena should be noted: * Implant placement results in the formation of a periprosthetic capsule which is the product of the inflammatory reaction and will isolate it from adjacent breast tissue * The periprosthetic capsule and adjacent breast tissue are chronically exposed to implant silicone. * Silicone in implants, even intact, has been shown to diffuse through the shell into the periprosthetic compartment and adjacent breast tissue * There is a phenomenon of erosion of the surface of the implants, particularly textured, responsible for the release of silicone particles within the periprosthetic capsule * The rupture of the prosthetic envelope is a dreaded complication, due to the alteration of the aesthetic result and the possibility of leakage of silicone gel * Since 2016, macrotextured implants have been implicated in the occurrence of anaplastic large cell lymphoma associated with breast implants (LAC-AIM) The presence of silicone in contact with tissues seems to promote an inflammatory environment, and this phenomenon seems increased if the implant is textured. Chronic inflammation induced by these devices can therefore have harmful consequences in the long term. INFLAMA study interested in the consequences of the presence of a silicone implant on local inflammatory phenomena within the periprosthetic capsule.

Multicenter Post-marketing Survey of SEBBIN Group Silicone Gel-filled Breast Implants

The aim of the study is to allow Groupe SEBBIN to communicate to competent authorities and to the scientific community data relative to the safety and effectiveness of SEBBIN silicone gel-filled breast implants.

Safety and Performance of Motiva® Sizers

The Motiva® Sizer clinical study is a four-year, multicenter, post-marketing, and cohort study, designed to confirm the safety and performance of Motiva® Sizer in breast augmentation or reconstruction procedures. The research will include 330 women, divided into two groups of 165 participants each (150 breast augmentation participants and 15 reconstruction participants). The Motiva® Sizer exposed group will consist of women who will undergo breast augmentation or reconstruction surgery with the use of Motiva® Sizer during the procedure, and a non-exposed group will consist of women who will undergo breast augmentation or reconstruction surgery without the use of Motiva® Sizer. This study will be conducted in Costa Rica. The main goal is to evaluate the safety and the performance of the Motiva® Sizer. To this end, the results of both groups will be compared in terms of surgical complications, surgeon's, and participant's satisfaction level as well as reoperation rates. After the augmentation or reconstruction surgery, participants will be scheduled for the following follow-up visits, (1) between 3 and 7 postoperative days, (2) between 3 and 6 postoperative weeks, (3) at 3 and (4) 6 postoperative months, and (5, 6 and 7) annually thereafter for a period of three consecutive years. In case any participant has an adverse event due to the procedure, and if required by the physician, an additional visit will be made to assess her, and this information as well as that of the scheduled visits should be recorded in the electronic data collection notebook.
