Structural deformities are usually deformities of the auricular cartilage or absence of the auricular cartilage, which are more severe and usually require surgical correction. Morphological deformities in newborns can be corrected using a non-invasive auricular orthopedic system, avoiding surgery, for newborns within one month of birth, and the earlier the treatment, the better the results. If the auricular deformity is a structural deformity, auricular reconstruction can be performed by means of rib cartilage reconstruction. The child needs to be 6 years old or older for the surgery, which is relatively inexpensive and the reconstructed cartilage is an autologous material with no rejection reactions. There are also many patients who choose biomaterial scaffolds to reconstruct the auricle, which are less dependent on their own conditions, more realistic and less invasive, but more costly and may have rejection reactions. Prosthetic ears are also a common surgical procedure, mainly made of silicone. They are not a living contour and cannot change in color with changes in body temperature like reconstructed ears, but the shape is very realistic and the cost is acceptable. This method is recommended for patients with burn or scald injuries that result in a disfigured ear.
