Rhinoplasty is an effective means to solve the problem of low nasal area, and it has an immediate surgical effect on the nose, especially on the low dorsum of the nose. The materials for rhinoplasty can be divided into two categories: autologous tissues such as rib cartilage or autologous bone, such as the outer plate of the autologous mandible, and allogeneic materials such as Medpor, expanded body, silicone, injected hyaluronic acid, etc. How to choose these materials? Here is how to choose the materials for rhinoplasty: Autologous tissue: generally autologous tissue is mostly used for nasal hypoplasia serious, patients because of congenital deformity or after trauma, more autologous tissue, rib cartilage, etc., because the donor area of the chest needs to leave a scar, so the cosmetic surgery patients are not applied, but there are some cosmetic patients choose this surgery, and accept the disadvantage of taking rib cartilage from the chest to leave a scar. Allograft material: Medpor, imported from the United States, is essentially a kind of prosthesis with holes, the advantage is that it has a certain degree of hardness and good biocompatibility, the disadvantage is that it is more expensive, because there are holes, so the blood vessels can easily grow into the prosthesis, once the patient feels that the shape is not satisfied or feel that the prosthesis is skewed, when the prosthesis needs to be removed, it is more troublesome and the surgery bleeds relatively more. Silicone prosthesis: this is the author’s favorite kind of prosthesis, the advantages are: soft and hard texture, easy to carve, easy to implant, 3 months after the formation of the envelope, and then touch the prosthesis, by external forces, and no longer displaced, once the patient feels unsatisfied with the shape or feel that the prosthesis is skewed, easy to take out, the price of domestic is relatively cheap, expensive imports, the essence of actually no difference, if the domestic rejection, the imported certainly If you reject the domestic ones, you will definitely reject the imported ones, because the ingredients are the same. Injected hyaluronic acid: the advantage is that the surgery is simple, the patient’s pain is small, immediate results, the disadvantage is more expensive, six months to one year after surgery absorption, note: this absorption can also be seen as an advantage, because the fight is the genuine goods will gradually absorb, if not absorbed, it is likely to be fake, or other substandard products.
