There are two kinds of total ear reconstruction surgery: staged surgery and one-off surgery. The traditional staging operation is a classic operation method, which generally includes three steps. The first operation is to embed the auricle bracket. First, the normal size of the contralateral auricle was sampled with transparent membrane, and then a costal cartilage was cut from the joint of the 7th to 9th costal cartilage on the right side of the patient's body. The doctor carefully carved the auricle bracket according to the shape of the sample, and then implanted the bracket into the pre-designed skin flap through the ear. Three months later, a second auricle plasty was performed. At this stage, the ear flap wrapped with cartilage scaffold is pulled forward, and a medium-thickness flap or a full-thickness flap is planted behind it, so that the reconstructed ear stands at an angle of about 60 and is close to the healthy side. After operation, a stent was placed behind the ear for fixation, and the skin graft survived for 3 ~ 4 months. In another two months, the third step of tragus and conchoplasty can be performed. The method is to cut the original scar on the front edge of auricle, make a tongue-shaped flap with pedicle in front, fold and sew it to form the tragus, and then lift the tongue flap and transplant it with medium-thick skin graft to make the concha cavity. At the same time, do some necessary trimming, so that the ear reconstruction operation will be successful.

In 1980s, it was applied according to the national conditions at that time. The advantage of this method is that it saves time and money, and it only takes two weeks to complete. The disadvantage is that the skin of mastoid region is not fully used, and some hair extends backward and upward, which makes the reconstructed ear thicker and has hair on the edge of helix. With the improvement of people's living standards, it is rarely used now. Disposable external ear reconstruction is made of high-tech biomaterial Medpor, which is a medical high-density porous polyethylene material. Experimental and clinical studies have proved that Medpor is non-toxic to human body and has good biocompatibility. After human blood vessels and tissues are implanted into human body, they can grow into prosthetic materials. At the same time, the strength and toughness of Medpor are acceptable, and it can be cut, processed, heated, molded and carved. It is an ideal scaffold material for auricle reconstruction. Medpor, a high-tech American biomedical material, is an advanced and safe substitute for artificial bone tissue, which has good histocompatibility, can grow capillaries and nerves, has good shape, no infection and almost no rejection. Through years of clinical experience and academic research, Dr. Wu Jianming has overcome the academic peak problem of external ear reconstruction. Since 1999, more than 500 cases of ear reconstruction have been performed with disposable external ear reconstruction, and all of them have achieved satisfactory results. The covering tissue is closely attached to the stent and has a good appearance. The reconstructed ears are lifelike and received rave reviews, and are known as the king of ear making. Its exquisite skills are almost unparalleled in the world, which requires not only years of painstaking study and hard study by Professor Wu, but also years of accumulated surgical experience and profound artistic attainments in aesthetics to achieve perfect results.
