Although rhinoplasty is not permanent, it lasts for a long time, and there is no problem for more than ten years. Autologous cartilage, in particular, is a material with low absorption, good viability and good biocompatibility, but it is slightly hard and has poor hand feel. The two materials, expansion and silica gel, are soft and easy to carve, but easy to dye and transmit light. Therefore, at present, the method of nasal augmentation with prosthetic nasal dorsum and autologous nasal tip can not only give full play to the advantages of autologous tissue, but also avoid the shortcomings of prosthetic materials, such as nasal atrophy, mental diameter damage, persistent secondary swelling, staining and so on. , but avoid supplementing ordinary collagen.
