Injection rhinoplasty is a non-surgical plastic surgery method that improves the shape of the nose by injecting fillers. It is widely used in facial plastic surgery. Compared with traditional surgical rhinoplasty, injection rhinoplasty is favored by more and more people because of its advantages such as less trauma, quick recovery and natural effect. Although injection rhinoplasty has many advantages, there are also risks. Among them, the displacement of injected fillers is a problem that many people are concerned about. This article will discuss in detail the principles of injection rhinoplasty, factors that may cause displacement, preventive measures and how to deal with the displacement problem.
1. Basic principles and commonly used materials for injection rhinoplasty
Injection rhinoplasty is usually performed by injecting absorbable or non-absorbable fillers such as hyaluronic acid, collagen, poly-L-lactic acid, polycaprolactone, etc. into the bridge, tip or base of the nose to modify the nose shape, raise the bridge or shape the tip of the nose. Unlike traditional surgical rhinoplasty, injection rhinoplasty does not require surgery, the process is simple, and the recovery period is short.
Hyaluronic acid (HA) : Hyaluronic acid is one of the most widely used injectable materials. It has good biocompatibility and plasticity. After injection, hyaluronic acid will be gradually absorbed in the body, but the effect is short-lived, generally 6 months to 1 year.
Collagen : As an injectable material, collagen has good biocompatibility, but its maintenance time is relatively short and some people may have allergic reactions.
Poly-L-lactic acid (PLLA) : This material shapes the nose by stimulating the body's collagen production, and the effect lasts longer, about 1-2 years.
Polycaprolactone (PCL) : PCL is a newer injectable material with better stability and long-term effectiveness, but it requires professional doctor operation to ensure the naturalness and safety of the effect.
2. Reasons for displacement of injection rhinoplasty fillers
Although injection rhinoplasty is relatively safe, the displacement of fillers is still a common problem. The displacement of fillers not only affects the beauty of the nose, but may also cause discomfort or complications in severe cases. The main reasons for the displacement of fillers are as follows :
Improper injection : Improper injection operation is one of the important reasons for the displacement of fillers. If the doctor performs the operation improperly and the injection position or depth is inaccurate, the filler may enter the wrong position, resulting in unnatural rhinoplasty effect or even displacement.
Filler characteristics : Different types of injectable materials have different stability and fluidity. For example, absorbable fillers such as hyaluronic acid and collagen will gradually be absorbed after injection, and due to their strong fluidity, slight displacement may occur. Relatively speaking, poly-lactic acid and polycaprolactone fillers have better stability and a lower probability of displacement.
Improper postoperative care : The quality of postoperative care has a direct impact on the stability of the injection rhinoplasty effect. For example, strenuous exercise or frequent touching of the nose in the early postoperative period may cause the filler to fail to be fixed in the ideal position, resulting in displacement.
External force : External pressure and impact are common causes of filler displacement after injection rhinoplasty. Impact or pressure on the nose may cause the filler to move or deform inside the nose.
Tissue relaxation or edema : Over time, the tissue at the injection site may relax or swell, which may also cause the position of the filler to change, especially for hyaluronic acid materials, which may affect its fixation effect as hydration changes.
3. How to prevent injection rhinoplasty fillers from shifting
Although injection rhinoplasty is a simple non-surgical plastic surgery method, in order to ensure the long-term stability and naturalness of the effect, it is very important to prevent the displacement of the filler after injection rhinoplasty. The following are some effective preventive measures:
Choose an experienced doctor : Choosing a professional plastic surgeon is the primary measure to prevent filler displacement. Professional doctors can perform precise injection operations based on the facial features of the patient, ensure that the filler is injected into the correct position, and avoid excessive or uneven injection.
Reasonable selection of injection materials : Choose appropriate injection materials according to personal needs and nasal conditions. For those who hope to maintain long-term effects, you can choose polylactic acid or polycaprolactone materials with better stability. For some people who pursue natural effects and do not mind short-term changes, hyaluronic acid materials are a more appropriate choice.
Reasonable care after surgery :
Avoid strenuous exercise and pressure : Avoid strenuous exercise after surgery, especially avoid touching or pressing the nose with your hands to prevent external force from causing the filler to shift.
Keep the wound clean : Keep the nose clean after surgery to avoid infection, and use antibiotics and other drugs as recommended by the doctor to prevent infection.
Avoid overinjection : Overinjection will not only increase the risk of filler displacement, but may also cause an unnatural nose shape. Therefore, when injecting, it is necessary to follow the principle of gradual filling to avoid injecting too much filler at one time.
Regular follow-up visits : After injection rhinoplasty, go to the hospital for regular follow-up visits to promptly detect and solve possible problems. The doctor can adjust the position of the filler according to the situation to ensure the stability of the nose shape.
4. How to deal with the displacement problem after injection rhinoplasty
If the filler shifts after injection rhinoplasty, appropriate measures should be taken to deal with it in a timely manner.
Minor displacement : If the displacement is not obvious and does not affect the overall effect, it generally does not require treatment. The filler may gradually stabilize and return to normal over time.
Larger displacement : If the filler is displaced significantly and affects the shape of the nose, you can consider adjusting the position through local massage or re-injection. If the effect is not ideal, the doctor may recommend partial adjustment or re-injection.
Serious complications : If serious complications occur after injection rhinoplasty, such as infection, allergic reaction, or severe displacement of the filler, surgery may be required to repair or remove the injected material.
Beauty Encyclopedia Tips:
As a simple and quick plastic surgery method, injection rhinoplasty has many advantages, but there is also the risk of filler displacement. Choosing an experienced doctor, choosing the right filling material, and providing proper postoperative care are the keys to preventing filler displacement. If displacement occurs, timely measures should be taken to avoid affecting the final effect. In short, fully understanding the surgical process and postoperative care before surgery can effectively reduce postoperative risks and achieve a more natural and lasting rhinoplasty effect.
