The concept of Dallas rhinoplasty originated in the United States and is a comprehensive rhinoplasty procedure. This approach discards the prosthesis and uses autologous cartilage to build the scaffold for nasal contouring. Generally, Europeans and Americans have better developed nasal cartilage and septal cartilage and have sufficient sources of cartilage for scaffold construction. There is a difference between Chinese nasal cartilage and Westerners, and most Chinese people have weaker nasal cartilage development. Therefore, not everyone in China is suitable for rhinoplasty. China mainly uses autologous rib cartilage for comprehensive nasal shaping. The advantage is that autologous material is not rejected and not easy to be infected, but the disadvantage is that it is more expensive and the surgery is more traumatic and easy to be bent and deformed. After Dallas rhinoplasty, the nose is more natural, mainly including the following advantages: 1, emphasizing the reshaping of the nose by adjusting the internal framework structure of the nose; 2, increasing the application of autologous tissues in rhinoplasty and using as few tissue substitutes as possible; 3, attaching importance to the overall design of the face, refining the height, length, width and curvature of the nose to enhance the overall beauty of the face; 4, pursuing the external nose While pursuing the external shape of the nose, improve and restore the basic physiological functions of the nose, such as ventilation function; 5. If the surgical environment is guaranteed, there are usually no adverse reactions after surgery; 6. The tissue compatibility is good and solid, and heals as one with the local tissue of the nose, which is easily fixed and will not be displaced.
