At present, there are many methods of rhinoplasty, including prosthesis implantation, autologous tissue transplantation and injection rhinoplasty.
Injection rhinoplasty:
Compared with the risk of plastic surgery with a moving knife, injecting hyaluronic acid or autologous fat into the nose is simple and convenient. There are two common injection materials: hyaluronic acid injection and autologous fat injection. Among them, hyaluronic acid injection takes effect quickly and does not need a recovery period, but the disadvantage of hyaluronic acid is that it gradually disappears with human metabolism. Autologous fat injection is to extract its own excess fat, and extract fat particles through purification technology for injection, which is relatively safe and will not cause rejection, but it requires high personal experience and technology of doctors, and the survival rate of injected cells will affect the surgical effect. Usually, a small amount of injections will be carried out several times to ensure the effect.
Implantable rhinoplasty:
According to personal facial features, the sculpture prosthesis is placed in the nose to achieve the purpose of increasing the back of the nose, which belongs to the first-class operation project. Middle-aged local anesthesia is needed during the operation. An incision is made in a specific part of the nose, and instruments are used to dive under the fascia of the back of the nose to form a corresponding tunnel, a prosthesis is implanted and finally sutured. Implant materials are common in silica gel and swelling.
Among them, silicone prosthesis is a common chin pad material, which is almost suitable for a variety of filling plastic surgery including chin plastic surgery, nose plastic surgery and chest plastic surgery. Silica gel material is non-toxic, has no side effects, stable performance and strong plasticity, but it is possible to reject it. Expansive materials are more difficult to handle than silicone rubber and will not cause rejection. Because of its good compatibility, opacity, and no change of heat and cold, the price is higher.
The core factors affecting the duration of rhinoplasty;
1. Regular hospital.
It is the basic factor and necessary condition for the success of all cosmetic plastic surgery. The injection project needs to ensure that the injection materials are qualified and legal; Prosthetic pad rhinoplasty requires regular surgery, sculpture is suitable for sterilization with its own silicone or inflatable prosthesis, local anesthesia is needed during the operation, and various steps such as submandibular incision and suture are needed. Regular hospitals provide a certain guarantee for the operation process.
2. Dr. Skills.
The project of rhinoplasty requires high technical level of doctors, and improper operation by general doctors can easily lead to side effects of rhinoplasty. For example, excessive or uneven injection of autologous fat will directly affect the survival rate of fat after it enters the body, and it is prone to sequelae such as collapse. In the way of implantation, the prosthesis material requires a higher level of shaping for doctors, and has strict requirements on the accuracy of implantation position and fixation.
3. Preoperative skin condition.
Any micro-plastic surgery will destroy the original balanced skin fiber system in the basal layer of the skin after entering the human body, and it also involves the integration and absorption with its own skin muscle base after entering the human body, so it is very important whether the skin is in a healthy state before operation. If the collagen fiber net at the base of the skin itself is not full and rich, it will not be able to accept autologous fat cells or prosthetic materials at one time after operation, and the absorption and fusion after operation will not achieve the expected effect, which will not only affect the surgical effect, but also have hidden dangers such as postoperative complications and side effects.
Instead of waiting for minor damage to happen before doing repair work, why not put an end to or minimize the side effects before doing it? There are no perfect operations and materials in the world, whether it is autologous fat rhinoplasty or prosthetic rhinoplasty. As the most popular rhinoplasty project in recent years, there are some technical problems from the injection of materials to the operation itself, and there are inevitable risks. Any cosmetic plastic surgery project is closely related to the individual's preoperative skin condition. For rhinoplasty, if the skin condition is poor before operation, the dermis is short of necessary nutrients, and the dermis is slender and fragile, then when the filler enters the body, the dermis cannot bear the load at one time, leading to the damage and rupture of the dermis. When the injectables (cell particles or materials) exceed the tolerance of nasal skin and soft tissue, the fillers (fat cells or prostheses) can not only be integrated with the surrounding environment. It may lead to complications such as incomplete skin healing, and eventually lead to serious consequences such as nasal skin ulceration, nasal skin perforation, crooked nose or nasal deformation. For many people, they attach great importance to postoperative repair. But in fact, the role of postoperative repair is obviously overestimated, and it is better to take precautions than to mend. What can really affect the operation process and effect is the adjustment and management of preoperative skin condition, which is often ignored by more people.
In order to ensure the safety of rhinoplasty and prolong the effect of rhinoplasty, the key is to supplement sufficient nutrition to the dermis before operation, especially collagen, the main component of dermal fibrous network. Only nano-scale collagen can really help the surgical effect, and small-molecule collagen can directly reach the dermis to supplement the needed nutrition without being absorbed by gastric juice.
