Surgery is to bury a medical solid silicone prosthesis under the skin of the nose, so that your bridge of the nose or tip of the nose protrudes to achieve the desired shape. Clinically, medical solid silica gel has no side effects on human body. You can always take it out when you don't want it. This kind of operation can be performed simply for people with low nose and good nose shape. The operation lasted for 3 to 5 minutes, with no pain or trace on the surface, and returned to normal in 4 days.

Second, what material is good for rhinoplasty:

The key to the effect of rhinoplasty is the surgeon's skill and the choice of rhinoplasty materials. Here, let's first review the application history of rhinoplasty materials. The earliest rhinoplasty materials are liquid paraffin, the mixture of paraffin and vaseline, silica gel injection, ivory and so on. Ivory has long been abandoned because of its superior material and poor carving. Liquid rhinoplasty materials, especially silicone injection, are called "meat injection", which was very popular in the early stage, but it was eliminated because it was easy to produce many sequelae.

At present, after extensive medical practice, the international popular rhinoplasty materials mainly include the following: medical silicone and autologous cartilage. Medical silica gel is non-toxic and harmless, and its histocompatibility is relatively stable. 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. 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.

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, I suggest that under the existing medical conditions, Chinese people still use solid silica gel or autologous cartilage for rhinoplasty.

To sum up, it is recommended that friends who want to do rhinoplasty choose original silicone or autologous cartilage.

Third, preoperative considerations:

1. Do not take drugs containing aspirin within two weeks before operation, because aspirin will reduce platelet coagulation function;

2. Patients with hypertension and diabetes should inform the doctor of their condition at the time of initial diagnosis, so that the attending doctor can confirm the operation plan;

3. Make sure that you are in good health before the operation, and there is no infectious disease or other body inflammation;

4. No makeup before operation;

5. Women should avoid menstrual period;

6. Men should quit smoking one week in advance.

Four, postoperative matters needing attention:

1, and try to avoid water accumulation in the surgical site within 7 days after operation;

2, ensure the surgical site clean, prevent infection. If there is blood scab or secretion on the wound, it can be wiped with sterile physiological saline.

3. The local wound after operation can be bandaged with pressure or cold compress with ice pack, but the pressure should not be too high to avoid damaging the surgical site. Once there is bleeding and severe hematoma after operation, you should go to the hospital for follow-up in time;

There should be a quiet and comfortable environment to recuperate after operation. Avoid heavy load and aggravate the swelling of the wound;

There will be some pain in the wound on the day of operation, but it will gradually decrease with the passage of time. Patients should not rush to take painkillers, because aspirin drugs will aggravate wound bleeding;

6. Avoid eating irritating foods such as peppers;

7, strictly abide by the doctor's advice and follow-up.
