1 Scar removal Remove all contracture scars, cut the lower skin to relax, and then pull it down to make it symmetrical with the opposite side.

2. Skin grafting and pressure. Take full-thickness skin graft and sew it carefully on the wound surface. Pack it and fix it under pressure12 days, then unpack it and take out stitches.

Nasal alar marginal defect: this kind of defect is often full-thickness defect, and spiral tissue including alar cartilage is the most ideal composite graft material. Not only can it be completed at one time, but also the quality, thickness, elasticity and color are very similar. If the required graft width is less than 1.5cm, the auricle deformation is not obvious, and the graft generally does not shrink after survival.

1 It can be used as a part of the lining by cutting the scar at the defect and turning it down into the nasal cavity, and at the same time, it can enlarge the tissue contact surface and make the graft easy to survive.

2. To cut the composite tissue at the outer edge of the external ear, it is necessary to carefully measure the size of the tissue block in advance, which is often slightly larger than necessary, and then cut the tissue so that the missing part of the external ear is slightly smaller than the stitched external ear. Women will not have aesthetic adverse consequences because of long hair covering.

3. Carefully suture the medial skin and nasal vestibule skin of the defect, but not the lateral skin of cartilage. Finally, suture the nasal vestibule, block the wound outside the alar with iodoform gauze, cover it with oil gauze and press it with impression glue to prevent infection. Internal and external pressure is the key to graft survival. If edema occurs, necrosis may occur. The dressing change was started 1 week after operation. If it is dark red, the graft will gradually turn bright red in 2 ~ 4 days, indicating that it has survived 10 days. After taking it out

If the alar defect is large and it is difficult to repair it with spiral composite tissue, a full-thickness flap can be cut above the defect, and its lower end can be folded down to the lower edge of the alar, and then the wound can be repaired with free flap and bandaged with pressure. This method may not be ideal for the skin with color difference on the nose, but it is also one of the effective methods of plastic surgery.
