The surface structure of the ear is complex and delicate, and shaping a realistic ear is a very complex and challenging surgery in plastic surgery. The surgical methods include Tanzer-Brent’s staged auricular reconstruction method, one-stage auricular reconstruction method, mastoid skin expansion auricular reconstruction method, double expander method, etc. I. Brent’s staging method is generally divided into four stages: Stage 1. In the second stage, rib cartilage is cut and sculpted to form an ear scaffold to be implanted under the skin of the mastoid area. The cartilage and skin are lifted and the skin is implanted on the dorsal surface of the cartilage. The whole process of ear screen and auricular cavity reconstruction takes about half to one year. Second, one-stage auricular reconstruction method: The skin of the mastoid area is lifted for the first time, and the cartilage scaffold is fixed on the cranial side wall, the anterior side of the scaffold is covered by the lifted skin, the back side is covered by the mastoid area and temporal fascia, and then the skin is implanted. The advantage of this method is that it saves time and can be completed in two weeks. The disadvantage of this method is that the skin of the mastoid area is not enough and extends upward with some hairs, so that the reconstructed ear is thicker and has hairs on the edge of the ear wheel, and more skin needs to be transplanted, and the scar of the skin donor area is obvious. The skin expansion method of ear reconstruction has many advantages such as adequate skin source, concealed postoperative scar and stable long-term results of the reconstructed ear, so it has become one of the most commonly used methods of ear reconstruction. The first stage is expander implantation, and 70-90ml expander is surgically implanted in the mastoid area behind the ear. After completion of water injection, it is best to maintain continuous expansion for at least 1 month, so that the flap retraction is smaller in the second stage of surgery and the post-reconstruction effect is better The second stage is auricular reconstruction, that is, the rib cartilage is taken for sculpting the ear scaffold during surgery, and then the expanded skin of the ear is used as the skin of the anterior auricle, and the part of the ear with insufficient skin behind the ear still needs to be implanted to complete the auricular reconstruction This stage of surgery requires hospitalization, and the hospitalization time The third stage is to perform the earlobe transposition earnail cavity and ear screen reconstruction on the basis of the completed ear reconstruction, so that the reconstructed ear is more perfect and realistic. In the second stage, the skin is expanded enough to cover the anterior and dorsal sides of the cartilage scaffold. With the large expander, no skin grafting is required in the second stage of surgery, which significantly reduces the scarring of the donor area, and there is no possibility of scaffold exposure due to poor skin graft survival or deformation of the reconstructed ear due to late contracture of the grafted skin after surgery. It has been proven to be a good and practical method. It has become a routine procedure in our department for ear reconstruction surgery.
