Abstract (original English)
Introduction Revision surgery following primary breast augmentation is common due to well-reported long-term limitations of permanent silicone implants. There are limited options for revision breast augmentation which avoids using silicone implants. Scaffold-guided breast tissue engineering (SGBTE) is a novel technique which uses breast scaffolds additively manufactured from medical grade polycaprolactone (mPCL), which is implanted and filled with autologous fat graft. This approach avoids limitations as observed with permanent silicone breast implants as the scaffold is porous and biodegradable. This clinical trial evaluates the safety and efficacy of SGBTE. Methods and analysis This study is an open, single-arm, monocentric, interventional, prospective clinical trial. The trial is being conducted at the Royal Brisbane and Women's Hospital (RBWH) in Herston (Queensland, Australia) of the Metro North Health Service. The trial investigates 15-20 women who require breast implant surgery and/or congenital breast defect correction surgery, where a mPCL breast scaffold is implanted and filled with autologous fat graft. The primary endpoint is postoperative device safety by assessing the rate of adverse device effect rate. Secondary endpoints include general adverse event frequency and severity, number of revision surgeries, general surgical outcomes and complications, patient-report
