Abstract
Nipple–areola complex reconstruction is a common procedure that often accompanies breast reconstruction. Historically, local skin flaps were utilized for nipple reconstruction, with more recent techniques exploring the addition of implanted material. Tissue engineering and regenerative medicine (TE&RM) represents a potential source of stable and biocompatible implantable tissue, which may have a positive effect on cosmetic outcomes. Conventional TE&RM techniques involve seeding a scaffold with the patients' own cells and using growth factors to promote survival. The clinical applicability of these techniques is limited by its cost and ability to produce sufficient volumes of viable tissue. This article reviews the evolution of nipple reconstruction techniques and current TE&RM protocols; these two fields are then combined to propose a novel approach of using TE&RM scaffolds to augment conventional nipple reconstruction.
Impact Statement
This work provides a comprehensive overview and critique of nipple reconstruction techniques to date. It then explores different tissue engineering concepts and how these may improve clinical outcomes for patients undergoing nipple reconstruction. A novel technique is proposed, whereby a three-dimensional-printed tissue-engineered construct is used as an autologous graft to assist nipple reconstruction.
