1, advantages and disadvantages of rhinoplasty materials
1. Silicone material
Medical silica gel is a widely used filling material for rhinoplasty in recent years. It has high temperature resistance, stable chemical properties, good corrosion resistance and histocompatibility, non-toxic, non-carcinogenic and non-teratogenic, and can be implanted into human body for a long time without absorption, with high success rate and few postoperative adverse reactions. Even if there are postoperative complications and the appearance is not ideal, it can be easily handled, and the nose shape will be restored to its original state, which will not cause the skin on the back of the nose to relax.
However, when using silicone filler for rhinoplasty, if the tension of nose tip shaping is too high, the symptoms of nose tip redness may appear, so this filler is generally not suitable for some people with low nose tip and short nose bridge. In addition, due to the hard texture of the silicone prosthesis, the touch is not so natural, and the nasal bone is integrally formed, which will not press the nose naturally upward. Moreover, due to its non-porous structure, human tissues cannot grow in, so special attention should be paid to protecting the nose in daily life after operation, so as to avoid strong impact and displacement and shaking.
2. Expansive materials
The expanded material is softer and more compatible than silica gel material, and the tissue can grow into the material. After rhinoplasty, the appearance and feel are natural and realistic, and the stability is good, and it will not shift under heavy pressure. It is also easier for beauty lovers who have a second rhinoplasty or have a thin nose tip.
However, intumescent materials are expensive. When filling, it is difficult to carve because of its soft texture, which requires doctors to have rich clinical experience. And once it needs to be taken out, it will be much more difficult than silica gel. In addition, the most serious problem after operation is the high infection rate, especially the long-term infection rate is much higher than that of silica gel.
3. Autogenous cartilage
At present, autologous cartilage is commonly used in rhinoplasty, such as costal cartilage, nasal septum cartilage and auricle cartilage. Because it is self-tissue, there is no rejection after implantation. But also can keep its original volume and cell morphology for a long time, and it is easy to be carved into the required size and morphology, so the postoperative appearance is more natural. In addition, autologous cartilage has good histocompatibility and is not easy to shift.
However, the use of autologous cartilage for filling is limited, and the operation is difficult and time-consuming. Moreover, taking cartilage from oneself can also cause other injuries, such as pneumothorax when taking costal cartilage.
Injection of rhinoplasty material
Hyaluronic acid (HA) is a commonly used material for rhinoplasty. Hyaluronic acid is used as a filler to fill the nose such as the bridge of the nose, and then it is shaped by the injection doctor. Just like an injection, it usually takes about 20~30 minutes, and it is quick to operate without surgery. As long as you take good care of it, it won't bring too much trouble to your daily life.
However, due to the short duration of rhinoplasty by injection, it can only last for 6~ 12 months at a time, and it needs to be injected again at intervals. The degree of rhinoplasty by injection is limited, which is not suitable for some beauty seekers with low nose. (Reporter Weng correspondent Lin)
2. What are the sequelae of rhinoplasty?
1. Bleeding: Bleeding may occur for some time after operation. In this case, it can be solved as usual. Raise your head, plug your nostrils with cotton and stay still. If you can't stop the bleeding, you should inform your plastic surgeon immediately. Usually, the plastic surgeon will put the filler into your nasal cavity again.
2, discomfort: there will be some discomfort in the nose after the operation. Breathing will be difficult, which is the result of swollen incision and upper respiratory tract infection or allergy. But this is temporary. If the symptoms persist, further treatment is needed, otherwise the nasal membrane will be displaced and the turbinate will be deformed, leading to respiratory system and sinus diseases.
3, infection: rhinoplasty surgery rarely occurs infection. If it happens, the result will be very serious. Infection is more likely to occur if the doctor operates when the patient has a cold or allergic reaction.
