The nose is located in the center of the face, and the nasal wing is the main part of the nasal composition, which is an integral part of the nostrils. If the nose is defective, it will seriously affect the aesthetics of the face, and if it is missing or collapsed, it will affect the shape of the nostrils and even the ventilation function, so for patients with nasal wing defects, proper treatment seems very necessary. To make up for the regret, the better way is to undergo nasal defect repair surgery. I. Indications 1, small area of the nasal wing simple defect; 2, the upper part of the nasal wing strip scar contracture caused by mild nasal wing defect; 3, the edge of the nasal wing mild strip lamellar defect; 4, the nasal skin is more relaxed. Surgical method 1.Excision of the scar of the defect and its lower part is cut open and turned downward into the nasal cavity, which can be used as part of the lining, while achieving the purpose of expanding the tissue contact surface, so that the graft piece can easily survive. 2. To cut the composite tissue from the outer edge of the ear shell, the size of the tissue piece to be taken must be carefully measured in advance, often slightly larger than needed. The tissue is cut to the desired size and then the missing part of the ear wheel is sutured together to make the ear shell slightly smaller after surgery. For women with long hair, there are no aesthetic consequences because their long hair is covered. 3. The removed earwheel tissue is carefully sutured at the defective area. The inner layer of skin and the nasal vestibule skin are sutured together. However, the cartilage is not sutured and the outer skin is sutured last. The nasal vestibule is blocked with oiled iodoform gauze, and the trauma on the outside of the nose is covered with oiled gauze and protected with impression adhesive to prevent infection. Internal and external pressure is the key to the survival of the grafted piece. If edema occurs, necrosis may occur. 1 week after surgery, the graft is changed. If the graft is already dark red, it will gradually change to bright red within 2 to 4 days. It indicates that it has survived, 10d after taking out the filled gauze, the removal of the suture can be a little later. 4.If the nasal defect is large, it is estimated that it is difficult to be repaired with the composite tissue of the ear wheel. Then, a full-thickness flap can be cut above the defect, turned downward, its lower end folded into the lower edge of the nasal wing, and then the free flap can be sutured to the wound surface. The flap is then sutured to the wound with a free flap and bandaged with pressure. This method may leave discolored skin on the nose and the result may not be ideal, but it is still one of the effective methods of plastic surgery.
