Microtia caused by congenital dysplasia brings serious physiological and psychological burden to the children.Traditional ear reconstruction methods have disadvantages such as trauma,infection and unstable effect,etc.With the development of tissue engineering,it has shown a great potential in ear reconstruction.Here,we discussed the construction of biomimetic microenvironment,morphological maintenance and immune response of transplantation area,thus to summary the current in vitro and in vivo studies in auricular cartilage tissue engineering.We hope to pro-vide beneficial information for other researchers.
