1. Incision determination: Gently press the upper helix with your fingers to make it round-ridged, so as to show the normal positions of the lateral ear helix and hind foot and determine the position of cartilage incision.

2. Make a fusiform incision behind the ear. After extensive dissection, make a cartilage incision at X, Y and Z according to the calibration point, and cut through the cartilage without cutting through the skin in front of the ear. The incision is slightly separated from the cartilage edge, or thinned with a steel brush, and the blade is thinned to facilitate curling.

3. Suture the cartilage into a tubular ligature from bottom to top with thread, and the tension shall be subject to keeping the proper shape of the ear. It is not necessary to tighten the thread to form a complete cartilage tube. Gently press the scaphoid, keep the normal angle between the auricle and the cranial side, and remove excess lunate cartilage.

4. In order to prevent the cartilage tube from slipping behind the concha, one or several stitches can be used to sew and fix it with the concha margin.

5, remove the excess skin behind the ear, suture, and finally wrap it with a dressing. The suture was removed on 10 day after operation, and the bandage was continued for three weeks after suture removal. Don't over-squeeze for three months.
