External ear defects can be repaired by transplanting ear cartilage or rib cartilage. 1. Transplantation of ear cartilage: If the patient’s outer ear loss is small, it can be repaired by transplanting a part of the ear cartilage from the patient’s own body to shape the defective part, or the patient can choose to perform the pulling together suture surgery, and then perform wedge excision suture. 2. Transplantation of rib cartilage: If the patient’s outer ear is severely defective, or there are symptoms of congenital pediatric deformity, it can be repaired by transplantation of rib cartilage. Firstly, choose the suitable rib cartilage from your own body to make the auricular scaffolding, and then transplant the skin to cover the auricular scaffolding for transplantation. Autologous cartilage graft repair of the outer ear has a high survival rate, along with low surgical risk. When choosing an outer ear reconstruction surgery, patients must choose a regular and professional hospital in order to maximize the survival rate of the outer ear graft.
