As a non-surgical cosmetic method, injection rhinoplasty has gradually become the choice of many people to improve the shape of their noses because of its advantages such as simplicity, speed and short recovery period. By injecting filling materials, problems such as low nose bridge and non-three-dimensional nose tip can be effectively improved. However, choosing the right injection material is crucial because the properties, effects and safety of different materials vary significantly. This article will explore the commonly used filling materials for injection rhinoplasty, analyze the advantages and disadvantages of various materials, and provide scientific reference for patients who intend to undergo rhinoplasty.
1. Hyaluronic Acid (HA)
Hyaluronic acid is a polysaccharide substance that naturally exists in human skin, joints and eyes. It has good moisturizing and filling effects. In recent years, hyaluronic acid has been widely used as one of the mainstream materials for injectable rhinoplasty because of its natural effects and easy operation.
Features and Benefits
Naturalness : Hyaluronic acid has good compatibility with human tissues. After injection, it can be quickly absorbed by the body and form a natural nose contour.
Adjustability : Hyaluronic acid is reversible. If the patient is not satisfied with the results or has adverse reactions, it can be repaired by injecting dissolving enzymes.
Safety : Since it is derived from substances of human origin, the risk of allergic reactions and rejection is low.
Disadvantages and risks
Short duration : The effect of hyaluronic acid injection usually lasts for 6 months to 1 year, which is relatively short-lived and requires regular supplementary injections.
Absorbability : Hyaluronic acid will be gradually absorbed by the body over time, which may lead to loss of effect and the need for repeated injections.
2. Poly-L-lactic Acid (PLLA)
Poly-L-lactic acid is an absorbable synthetic material that is often used in injectable rhinoplasty to stimulate the body's own collagen production, thereby achieving a long-lasting rhinoplasty effect.
Features and Benefits
Stimulate collagen production : PLLA can gradually enhance the three-dimensional sense of the nose in the long term by promoting the production of collagen, making the effect more natural.
Durability : The effect after injection can last for 2 to 3 years. Compared with hyaluronic acid, PLLA has more significant durability.
Suitable for most people : PLLA is suitable for sculpting the bridge and tip of the nose, and can effectively improve the nose contour.
Disadvantages and risks
Multiple injections are required : In order to achieve the ideal effect, PLLA usually requires multiple injections, and the effect gradually appears after each injection.
Uneven filling may occur : Since collagen production takes time, some patients may experience uneven filling in the early stages.
Slow absorption : PLLA is absorbed slowly in the body and takes a long time to recover.
3. Silicone
Silicone is a non-absorbable material that is often used as an implant material in rhinoplasty surgery. In injectable rhinoplasty, silicone is also occasionally used as a filler material. Although it is less commonly used for injection, it is still favored by some patients due to its stability.
Features and Benefits
Long-term effect : Silicone has long-term stability. The effect after injection usually lasts for several years and is not easily absorbed by the body.
Stability : Silicone hardly decomposes in the body and can provide long-term support for the nose.
Disadvantages and risks
Difficult to repair : Once the silicone injection is completed, if the effect is not ideal or adverse reactions occur, it is difficult to repair it through simple dissolution treatment.
Possible induration and foreign body sensation : In some patients, silicone may cause localized induration or foreign body sensation.
Risk of infection : Although the use of silicone is very safe, improper injection or improper care may still lead to local infection or complications.
4. Cross-linked HA
Compared with ordinary hyaluronic acid, cross-linked hyaluronic acid uses cross-linking technology to make its molecular structure more stable, enhancing the durability and filling effect of the material. It is often used in rhinoplasty treatments that require stronger support.
Features and Benefits
Enhanced durability : The effects of cross-linked hyaluronic acid last longer than regular hyaluronic acid, usually lasting more than 12 months.
Suitable for nose shaping : Cross-linked hyaluronic acid has strong viscosity and can provide better support, making it very suitable for improving the shape of the nose bridge or nose tip.
Natural results : The injection produces natural results and allows you to quickly return to your daily life.
Disadvantages and risks
May cause swelling : Some people may experience mild swelling after the injection, which usually subsides within a few days.
Poor solubility : Compared with ordinary hyaluronic acid, cross-linked hyaluronic acid is more stable and not easy to remove by enzyme dissolution treatment. Once the effect is unsatisfactory or complications occur, repair will be more difficult.
5. Autologous fat
Autologous fat injection is a rhinoplasty method that extracts the patient's own fat tissue, processes it, and then injects it into the nose. The biggest advantage of this method is that it reduces the risk of rejection.
Features and Benefits
Good biocompatibility : Since the patient’s own fat cells are used, the risk of rejection and allergic reactions is almost zero.
Natural effect : The injection of autologous fat has a more natural effect and can blend with surrounding tissues, presenting a good surgical effect.
Double effect : In addition to the rhinoplasty effect, after fat transplantation, a yiding shaping effect can be achieved in the fat collection area.
Disadvantages and risks
Fat absorption problem : Part of the injected fat may be absorbed, resulting in unstable results. Some patients may need multiple injections to maintain the desired effect.
Surgical complexity : Compared with other filling materials, autologous fat injection requires an additional fat extraction process, and the surgical procedure is more complicated.
Beauty Encyclopedia Tips:
Injection rhinoplasty is a relatively safe and effective non-surgical cosmetic method, but choosing the right filling material is crucial. Different materials have their own characteristics, advantages and disadvantages, and indications. When choosing materials, patients should fully communicate with professional plastic surgeons to understand the applicability and potential risks of each material to ensure that the final effect is consistent with their own needs. At the same time, postoperative care and regular follow-up are equally important, which can effectively avoid the occurrence of complications and prolong the duration of the rhinoplasty effect.
