Microtia is a combined congenital malformation with the prevalence of one case per 10,000–15,000 newborns, which accounts for 50% of all congenital malformations. Treatment of microtia is a challenging task. Numerous solutions have been proposed, however, none of these options guarantee good functional and aesthetic outcome. High hopes for solving the problem are placed on advances in reconstructive surgery. The study was aimed to determine the possibility of using advanced biocompatible endoprostheses manufactured using the tissue engineering technologies. Two closely related male 2-year-old minipigs of the Sus salvanius breed underwent implantation of bioengineered implants manufactured by combined 3D bioprinting with application of the collagen solution containing autologous cartilage tissue cells under the temporal fascia. The samples were collected 3 months later. Histological examination and immunohistochemistry showed that the implanted endoprosthesis initiated the development of regenerated connective tissue and its own vasculature in 100% of cases, thereby ensuring cell viability and integrity of biological structures; furthermore, no facts of the endoprosthesis rejection or resorption were reported. We have concluded that the developed implant manufacturing method is promising and can provide the basis for creation of domestic porous ear implants based on biocompatible polymeric materials, hydrogels, and autologous cellular material. It is necessary to further test the auricular implant using biological models.
