1. What are the methods of rhinoplasty?
1, medical silica gel
Because it is non-toxic and harmless, its histocompatibility is relatively stable, and it is the main medical prosthesis material. Especially in recent years, the use of medical silica gel has become more and more standardized, with fewer sequelae and complications, so it has been widely used in clinic. At present, the commonly used silicone rhinoplasty materials are basically formed and can be used with a little modification according to everyone's situation; Second, the color is similar to the skin, and there will be no false feeling; Third, it is easy to plug and pull, and it can be completely taken out as soon as possible in the case of infection and rejection, leaving no hidden dangers. So this kind of rhinoplasty material is the most widely used in the world at present.
2. Autogenous cartilage
Autologous cartilage and bone have the advantages of permanent fusion with nasal tissue, no rejection and strong anti-infection ability; * * * The same disadvantage is that it increases the difficulty of operation and requires higher operation level and requirements. At the same time, you need to have considerable experience in the use and carving of bones and cartilage. Compared with autogenous bone, autogenous cartilage is more commonly used, because its hardness is more closely related to the dorsal nasal cartilage and it is easier to shape.
3. Artificial bone
There is also an artificial bone (hydroxyapatite), which is also used as a medical material in clinic. At present, some people in China use it as a liquid for injecting rhinoplasty. In fact, rhinoplasty by injection has not been carried out in developed countries, and there is no literature report on rhinoplasty by injection of artificial bone. The latest research in Japan 65438-0997 shows that the application of artificial bone in plastic surgery is only suitable for bone defect or depression deformation at present. Because the artificial bone fixation molding process is a heat dissipation process, premature filling will cause thermal damage to the surrounding tissues, so it can only be made into a toothpaste-like lake and filled when it is about to be fixed. Artificial bone has been widely used in clinic for only 10 years, and its long-term effect needs to be observed and further studied. Even if the artificial bone is perfect, it is still "artificial", and there is no definite basis for whether the ability to resist external infection is the same as that of human tissue. Moreover, rhinoplasty with artificial bone injection must be completely removed once infection occurs. Therefore, under the existing medical conditions, it is best for Chinese to use solid silica gel or autologous cartilage for rhinoplasty.
There is nothing wrong with women's pursuit of beauty, but everything must be measured, and plastic surgery is the same. After all, these operations are also dangerous, so women should be fully prepared when doing plastic surgery.
Second, the precautions for rhinoplasty
1, within one week after augmentation rhinoplasty, it is necessary to avoid water on the surgical site, and also ensure the cleanliness of the surgical site to prevent wound infection. If there is blood scab or other secretion on the wound, don't buckle it by hand, but gently wipe it with sterile saline. These points must be paid attention to after rhinoplasty and play a very important role in the recovery time.
2. After the operation, the wound should be bandaged with pressure or cold compress with ice packs, but the pressure should not be too high, which will easily damage the surgical site. If there is bleeding or serious hematoma after rhinoplasty, you must go to the plastic surgery institution for a follow-up visit in time. Rest in a quiet and comfortable environment after the operation. Avoid the load and then aggravate the swelling of the wound.
3. There will be a feeling of wound pain on the second day after rhinoplasty, and the general pain will gradually decrease with time. At this time, patients undergoing surgery should try not to take painkillers, because painkillers contain aspirin, which will aggravate wound bleeding. When the pain is really unbearable, consult a doctor to avoid unnecessary trouble.
4. When resting after surgery, it is best to choose a semi-recumbent position to sleep and rest, which is beneficial to blood circulation. Don't bow your head on the first day of operation to prevent bleeding. You can eat some lost food on the second day and the third day, and you can't eat irritating food.
5. The surgical site usually swells for a while. Even after this phenomenon disappears, the surgical site should not eat spicy food or drink alcohol until it is fully recovered. After the operation, the nose will feel tight and swollen after getting up early, and it will usually disappear after more than a month.
