Abstract:Background: Hypopharynx reconstruction after hypopharyngectomy is still a great challenge. Perfusion decellularization is for extracellular matrix (ECM) scaffolding and had been used in organ reconstruction. Our study aimed to prepare an acellular, natural, three-dimensional (3D) biological hypopharynx with vascular pedicle scaffold as the substitute materials to reconstruct hypopharynx. Result: Scanning electron microscope (SEM) and immuno showed that the decellularized hypopharynx with vascular pedicle scaff… Show more
