Ear reconstruction surgery is mainly done by taking the patient’s rib bone and sculpting a scaffold to support the skin behind the ear and reconstruct the ear, i.e., sculpting an outline of the ear through the rib bone and then transplanting it to the patient’s ear area, which requires a high surgical technique. There are many ear reconstruction surgeries, currently there are direct burial method, expansion method, and the expansion method is divided into expansion full package method and half package method. The above three methods generally require three phases according to the residual ear, and the risks of each phase are different, as follows: 1. Phase I: the risk of burying the expander, which mainly includes infection, bleeding, hematoma, and later may appear after the skin is broken and the expander leaks and seeps out; 2. Phase II: mainly infection, bleeding, and if the rib is taken improperly, the pleura that may be pierced may cause pneumothorax or hemopneumothorax. If the protection is not good, the cartilage of the stent may be exposed; 3. Phase 3: including infection, bleeding and other routine risks, doing flap transfer may result in necrosis, partial necrosis or scar growth of the flap. The ear will continue to swell for a period of time after the three stages are done. By far the biggest risk of ear reconstruction surgery is infection because the cartilage is not supplied by blood when it is transplanted in, but by tissue fluid. The cartilage itself is very poor at resisting infection, and if it is accidentally infected, the cartilage will absorb and deform the ear. Therefore, this surgery needs to be performed by a very experienced surgeon so that the chance of infection can be kept to a minimum.
