Scaffold-guided Breast Implant Revision Surgery

The objective of this clinical trial is to generate robust data that demonstrates clinical performance and safety of a polycaprolactone (PCL) breast scaffold combined with autologous fat grafting (AFG) in women who seek a revision surgery of a breast implant used for breast augmentation. The material (PCL) has been in clinical use for many decades and is absorbable. This study follows the successful completion of a 2-year evaluation of the safety and feasibility of this technique performed by the Royal Brisbane and Women's Hospital (ClinicalTrials.gov ID: NCT05437757). The main question it aims to answer is: "Is PCL Breast Scaffold with autologous fat graft a safe and effective method of soft tissue reconstruction following breast implant revision?". Participants will: * Undergo removal of their existing silicone breast implant (if not previously removed), * Receive implantation of a PCL Breast Scaffold combined with autologous fat grafting (AFG), and * Attend follow-up visits at 1 week, 3 months, 6 months, and annually for up to 5 years for clinical assessments and questionnaires.

LTFU of PCL Breast Scaffolds Used in 2021-BRV-004

The objective of this study is to assess the long-term safety and performance of the PCL Breast Scaffold in women who previously underwent breast silicone implant revision and received the PCL Breast Scaffold combined with autologous fat grafting (AFG) in the 2021-BRV-004 clinical trial (ClinicalTrials.gov ID: NCT05437757). In addition, this study will investigate the suitability of mammography in the subset of patients that fall into the national breast screening age category - individuals aged 40 years and older. The main questions this study aims to answer are: * "Is the PCL Breast Scaffold combined with autologous fat grafting a safe and effective method of soft-tissue reconstruction following breast implant revision?" * "Is mammography a suitable follow-up screening and diagnostic tool for patients implanted with the PCL Breast Scaffold?" Participants will attend annual follow-up visits from 3 to 5 years after PCL Breast Scaffold implantation for clinical assessments and patient-reported outcome questionnaires.

Scaffold-guided Breast Surgery

The clinical trial is testing the use of a novel method to grow new tissue within the breast injecting fat tissue harvested from patient's own fat deposits. A scaffold implant acts as a resorbable frame to support this growth of cells. The scaffold will be resorbed within at least 3 years. The main assumption of this clinical trial is that the method used is safe and effective for treatment of women requiring a silicone implant and /or correction of breast defect and/or deformity. The other assumption is that this method is applicable to a wider range of tissue defects, such as breast reconstruction after breast tissue removal. The new method is called '3D printed scaffold-based soft tissue regeneration', and uses a combination of own fat cells (called adipocytes) with a 3D printed scaffold to support soft tissue regeneration using the natural healing processes in their body. This substance is resorbable and is similar to the substance used for sutures and stitches that are dissolvable or resorbable in the body. The substance used for the scaffold is already Therapeutic Goods Administration (TGA) approved for bone reconstruction of the skull. The implanted scaffold degrades over time, leaving the their own tissue in its place. The combination of scaffold implantation and their own fat cells is the novel method in this trial. Conventional liposuction techniques are used from another site on the patients body to harvest their fat cells.
