Question: I’ve had several patients request breast reconstruction following a mastectomy for breast cancer treatment, but they would like to avoid using implants. Are there advances in breast reconstruction that might appeal to our patients? Colorado Subscriber Answer: Several options are available for those seeking breast reconstruction, and here’s one that comes to mind: Headquartered in France, Lattice Medical, has developed a breast bioprosthesis over six years of research at Lille University Hospital. The Mattisse is a 3D-printed bioresorbable tissue engineering chamber that allows patients to naturally regrow breast tissue. The 3D-printed device features a porous base and a domed design that can be customized to meet the patient’s volume and shape. Once inserted, breast tissue is inserted into the bioprosthesis. As the tissue grows inside the domed structure, the prosthesis begins to break down until the breast is naturally regenerated.
