2. Use small scissors to extend into the back of the nose from the incision, peel and cut, and separate the adhesion between the nasal bone and the subcutaneous tissue at the back of the nose. It is necessary to completely relax the nasal bone and subcutaneous tissue from the lateral brow to the maxillary bone on the back of the nose.
3. If it is a shuttle type, you can put it in to observe the nose type correction. First of all, we should pay attention to whether the base and saddle nose bone depression of the model are suitable. When pressing the tip of the nose, will the root end of the model tilt up? If the base is not suitable, the model will be easily distorted and deformed. If it is too large or the base is not suitable, it can be modified appropriately. If it is too small, you can exchange it for a larger model.
4. If the L-shaped model is adopted, it should be separated in the middle of the columella until the bottom of the columella reaches the maxillary nasal spine downwards. If the transplanted model is cartilage, it should be separated from the mucosa of nasal septum and put into the model. If it is a soft plastic model, you can fold it down and put it in the pillar of the nose column, or you can fold it up and put it in your nose, and then loosen it. Although there are pillars in the nasal columella to press the tip of the nose, the tension of the model should not be too high, otherwise it may hinder the blood supply of the skin on the back of the nose. Should cause necrosis, the model will wear, especially the plastic model is more likely to cause surgical failure. Therefore, if the tension is too high, the model can be taken out and trimmed until it is completely tension-free and suitable.
5. If the nasal contour correction is satisfactory, the skin of the incision can be sutured with silk thread, a little gauze is covered on the back of the nose, and the nasal contour is fixed with a nasal back bracket (made of anti-tooth glue or aluminum sheet) and adhesive tape.
