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 absorbable frame to support this growth of cells. The scaffold will be absorbed 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 absorbable and is similar to the substance used for sutures and stitches that are dissolvable or absorbable 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.
