Zhao Hongyi, director of the Third Hospital of Beijing Medical University, replied: There is an area in the comprehensive nasal surgery that everyone is most concerned about, and it is also a part that may cause more problems in the operation, that is, the extension of our nasal tip. In fact, our nose tip extends in two directions, one is downward and the other is forward. Different schemes may have different materials and treatment methods. For example, we hope that the extension of the tip of the nose will go down again, which will make our nose look longer and make this area more prominent. Then what we may use most is the transplantation of nasal septal cartilage, which can be clamped at this angle to make it go further down, or we can slice the costal cartilage and then support it. So when we say that the tip of the nose extends forward, we mean the extension of this area. After the pillar is supported, we will superimpose an ear cartilage on it, which will make the tip of the nose look more upturned and lovely, and then the relationship with the back of the nose will be more harmonious. Then this is when we lengthen the nasal tip, different directions, different materials and different surgical designs.
