Wind ear, also known as fan ear, is a common congenital malformation of external ear. Cut the skin between the design mark points behind the ear, peel it off along the cartilage surface to fully expose the cartilage, cut several pieces of cartilage in parallel between the two rows of design points, sew the cartilage into a tube shape with silk thread, remove the excess skin behind the ear, remove the stitches 7- 10 days after the skin is intermittently stitched, and hold the auricle backwards with a wide elastic band for 3-6 months to prevent recurrence. Cup-shaped ear correction Cup-shaped ear, also called lifting ear and ring-shrinking ear, is a congenital auricle deformity. After local infiltration anesthesia, a V-shaped incision was made at the root of the helix, and the triangular flap was separated along the subcutaneous direction. After V-shaped suture, the triangular flap was bound and fixed, and the stitches were removed for 7 days. Correction of earlobe cleft 1, direct suture: if the earlobe is large, the full-thickness tissue of the cleft edge can be removed and the skin sutured contraposition. 2. "Z" plastic surgery: cut the skin at the edge of earlobe cleft, design two "Z" arms and cut them, sew two triangular flaps on the same side, and then sew the front and back skin respectively. 3. Flap rotation method: design a full-thickness flap on both sides of earlobe fissure, rotate the left flap to the right and the right flap to the left after cutting, cut the edge of the inward-rotating flap, and then suture it contraposition. Correction of earlobe injury 1 and "u" flap correction: design a "u" flap under the external auditory canal, which is larger than the earlobe. After incision and upward peeling, the two sides of the flap were stitched, and the trailing edge of the earlobe defect was stitched with the edge of the flap, and the skin of the donor site was separated to both sides. 2. Rotation correction of retroauricular flap: the flap was designed under the earlobe, and the lower end was rotated forward after incision and peeling, and the donor skin was separated to both sides and sutured directly. 3. Correction of Yimen flap: Design a flap slightly wider than the defect in the mastoid region behind the ear. After incision and peeling, the upper edge of the flap was sutured with the defect wound, and the edge of the donor wound was peeled off and then sutured intermittently. Generally, the pedicle is broken in three weeks, and then the flap is turned up to make the meat face the opposite side, and the ear lobe is formed by suturing the posterior and lateral sides of the ear. The second-stage total ear reconstruction of the expander used in auricle reconstruction mainly uses the skin expander to slowly expand the hairless skin in the mastoid region, and then carves the ear bracket from the patient's own costal cartilage to complete the ear reconstruction. It has the advantages of abundant skin, natural skin color and texture, clear outline and strong three-dimensional sense, and is the first choice for total ear reconstruction in the world at present. Precautions before and after operation Precautions before operation: Patients with ear deformity can undergo ear plastic surgery. Patients should have a physical examination before undergoing ear plastic surgery. People with heart disease and scar constitution are not suitable for ear plastic surgery. Postoperative precautions: 1. Antibiotics were routinely used for 3-5 days after operation. The suture in the reconstructed ear and the area behind the ear was removed in 12 days, and it still needs to be bandaged for several days after the suture removal. 2. Pay attention to packing the groove behind the ear with gauze when dressing. All dressings can be removed three weeks after operation, and the hair on the edge of the helix should be carefully removed within half a year to avoid excessive pressure on ear reconstruction. 3. The stitches were removed 12 days after operation, and there should be no external impact in the short term after operation.
