Zhao Hongyi, director of the Third Hospital of Beijing Medical University, replied: So the so-called split rhinoplasty is actually relative to the one-piece rhinoplasty we used before, so our previous rhinoplasty operations were basically based on the implantation of prostheses. Some of the prostheses used in our rhinoplasty are L-shaped and some are willow-shaped, so they are mainly composed of two structures: the back of the nose and the columella, which are as complete as the position of the tip of the nose. As for the integral prosthesis, it is integrally formed from the back of the nose to the tip of the nose to the columella, so it has been used in the past. With the improvement of the naturalness of prosthesis, prosthesis is designed into segments, such as the segment with nasal dorsum, the segment with nasal tip and the segment with nasal columella. Then through this split design, the whole nose is realized.
