Although rhinoplasty is not permanent, it lasts for a relatively long time. Generally, there is no problem for more than ten years, especially autologous cartilage, because it is its own material and can be absorbed. Low, good survival and biocompatibility, but slightly hard and poor hand experience. The two materials, expanded silicone and silicone, are relatively soft, easy to carve and shape, and have realistic shapes, but are easy to stain and permeate. Therefore, rhinoplasty now mostly adopts the method of prosthetic nasal dorsum + autologous nose tip. This can not only give full play to the advantages of autologous tissue, but also avoid the shortcomings of the prosthetic material itself, such as: nose tip atrophy, diameter damage, and continuous swelling. , infection, etc., but be careful not to supplement ordinary collagen. Implantation of the prosthesis under the skin will promote the secretion of collagen in the body. In addition, supplementation will not be absorbed by the body, and will also cause excessive accumulation in the body, causing scars on the skin's epidermis. Dark color.
