The latest treatments for microtia include: Tissue Engineering Ear Reconstruction, Medpor Stent Implantation Phase I Ear Reconstruction, and Autologous Rib Cartilage Stent Ear Reconstruction. 1. Autologous rib cartilage scaffold ear reconstruction: computerized digital technology is used to design an ideal contour according to the patient’s healthy ear as a template, prepare an auricular scaffold according to this contour, then evenly distribute the stem cells on the scaffold, add a series of factors to induce and promote the directional differentiation of the cells, and carry out in-vitro cultivation, and then implant them into the living body after the successful differentiation of the stem cells and the shaping of the auricular contour. 2. Medpor scaffold implantation for one-stage auricular reconstruction: Medpor material is made of high-density porous polyethylene, which is an inert material. This method mainly involves sculpting the Medpor biomaterial into an auricular scaffold in accordance with the healthy side of the ear diaphragm sheet, then turning the head fascia to wrap the scaffold, followed by skin implantation, continuous negative pressure suction after the tissue coverage, so that the soft tissues are tightly adhered to the surface of the scaffold to form the auricular microstructure. 3. Autologous rib cartilage scaffold ear reconstruction: it is mainly divided into four phases, the first phase of the surgery is to cut 8~10 ribs cartilage, sculpted into auricular cartilage scaffold, the size, shape and outline are basically similar to the healthy side of the external auricle, and then the sculpted scaffolds will be buried into the subcutaneous; the remaining three phases are for the transposition of the earlobe, the reconstruction of the ear screen, and the lifting of the auricle from the lateral wall of the skull to the local wrapping of the superficial temporal fascia, and the implantation of the skin behind the ear. The specific treatment measures for patients still need to be chosen by the doctor according to the patient’s condition.
