Hyaluronic acid rhinoplasty

Hyaluronic acid rhinoplasty surgery must be performed in a formal and standardized place, so that if an accident occurs, compensation can be obtained in a timely manner. When performing rhinoplasty with hyaluronic acid, you must be careful not to come into contact with cold water. When performing rhinoplasty with hyaluronic acid, you must pay attention to whether the nose has undergone other surgeries. During the hyaluronic acid surgery, you must learn how to nourish the nerves in the nose and make good preoperative preparations.

Hyaluronic acid rhinoplasty is a surgical procedure to reshape the nose by injecting hyaluronic acid to achieve the rhinoplasty effect. In September 2014, the State Food and Drug Administration launched a strict investigation into illegal and irregular activities involving injectable hyaluronic acid.

Brief History

In 1934, Meyer, a professor of ophthalmology at Columbia University in the United States, and his colleagues first isolated hyaluronic acid from the vitreous body of bovine eyes and analyzed its structure. Because uronic acid is extracted from Hyaloid. In the 1960s and 1980s, the price of each kilogram of hyaluronic acid for ophthalmic use was as high as US$10,000, so it was rarely used in the market.

In 1993, German doctors first injected hyaluronic acid directly into the synovium of patients' bone joints. The results showed that patients could quickly eliminate joint pain and regain the ability to walk. It has since been used to treat arthritis in Western countries. In terms of price, the price of hyaluronic acid for cosmetics is generally 15,000-20,000 yuan per kilogram, food grade is 10,000 yuan, and medicinal grade is 50,000-60,000 yuan per kilogram.

Hyaluronic acid principle

Hyaluronic acid, also known as uronic acid and hyaluronic acid in English, is also called hyaluronic acid in medical books. It is a straight-chain high-molecular polysaccharide composed of disaccharide units (glucuronic acid-N-ethylthioaminoglucose). It is a substance that exists naturally in tissues and is also one of the components of human dermis. Hyaluronic acid injection is the process of injecting hyaluronic acid as a filler into the dermis wrinkles, depressions or areas that need to be plumped up, such as the lips, cheeks, nose bridge, chin, scars, etc., which can achieve the effect of immediate wrinkle removal and changing appearance. In the past, collagen was used as the structure in the dermis. If we use the analogy of building a house with reinforced concrete, collagen is like the steel frame, and hyaluronic acid is like the cement poured in after the steel bars are built. The expansion effect of hyaluronic acid prevents the steel frame from collapsing. However, the injected hyaluronic acid will be slowly absorbed by the human body, so if you want to maintain the effect, intermittent injections are required. Once regular injections are no longer continued, the effects will gradually fade and eventually disappear completely.

Treatment Process

The most important thing is to discuss with the doctor in advance the area to be injected and the shape you want to create. If necessary, you must sign a consent form and take photos before and after the operation for comparison. During treatment, the area will be cleaned and disinfected first, anesthetic will be applied and pressed with plastic film, and the injection will be performed only after the anesthetic effect is ensured.

Validity

Depending on individual circumstances, the therapeutic effect can last from 6 months to 1 year. In order to make hyaluronic acid rhinoplasty effective for a longer period of time, we recommend two to three injections of hyaluronic acid. In order to achieve the best and longer-lasting results, do not expose the treated area to extreme heat, such as sunbathing or sun exposure, or extreme cold after surgery. Avoid contact with the injection area for 6 hours after surgery. During this time, gentle cleansing with water and soap can be used, and light makeup removal is permitted.

side effect

After the injection of hyaluronic acid, temporary slight redness, swelling, and itching may occur, but these discomforts usually disappear after a few days. Hyaluronic acid has fewer side effects. It is not a protein, so the chance of causing an allergic reaction is much less. It is also easily decomposed by the human body, so it has fewer long-term side effects on the human body.

Security

Hyaluronic acid injection is very safe to use, and the chance of allergy is very low. Generally speaking, there is no need to do a skin sensitivity test first. However, there are still some complications that deserve our attention, such as arterial embolism, fibrosis and granulation tissue formation, local redness, swelling and pain, local hematoma and even infection, patient anxiety and foreign body sensation, etc.

shortcoming

(1) The disadvantage of hyaluronic acid rhinoplasty is that immediately after the procedure, the skin will feel granular, which will disappear after about 3 days. Hyaluronic acid rhinoplasty may cause temporary slight redness, swelling, and itching, which usually disappears after a few days.

Basic symptoms for all surgeries.

(2) Generally, hyaluronic acid rhinoplasty can last for about 6-12 months. It is not a very long time. It is recommended to inject the second injection of hyaluronic acid rhinoplasty within 4-8 months after the first injection, otherwise it will return to its previous appearance after absorption. Because hyaluronic acid is a component of human tissue, it will be slowly absorbed; and hyaluronic acid rhinoplasty can be injected a second time for continuous improvement. It seems that the original disadvantage of hyaluronic acid injection rhinoplasty has also become a potential advantage.

(3) For simple raised nasal root, hyaluronic acid injection may have a certain effect, and hyaluronic acid is absorbed after rhinoplasty. However, for more complex nasal shape modification, it is definitely not possible without shaping of autologous cartilage or prosthesis.

advantage

1) Biocompatibility & Biodegradability

Hyaluronic acid can naturally combine with skin tissue and deliver some important nutrients to the tissue. There is no gel displacement at the injection site.

2) Persistence

Due to its natural properties, hyaluronic acid remaining at the injection site can be quickly degraded. This highlights a crucial property in the cross-linking process. The durability of hyaluronic acid is directly related to the strength of the molecular cross-links. The higher the cross-link strength, the longer the product will last on the skin.

3) Ultra-safe use characteristics

The non-animal derived ingredients in hyaluronic acid minimize the risk of allergic reactions caused by injections. Even people who are allergic to food (such as eggs, beef, etc.) can calmly receive hyaluronic acid injections without worrying about adverse reactions or the need for skin testing before injection. Other injectable products contain bovine collagen or hyaluronic acid extracted from rooster combs, which carry the risk of disease transmission and can cause allergic reactions when used. Hyaluronic acid can be naturally absorbed and degraded by skin tissue, while also being able to deliver some important nutrients to the tissue, such as oxygen and hormones. Because the gel particles can flow freely between cells, the skin appears naturally soft and healthy.

4) High viscoelasticity

Highly viscoelastic filler products utilize our patented mesh processing technology. The high viscoelasticity treatment process of the product prolongs the time the product acts on the dermis and improves its ability to repair deep wrinkles or numerous fine lines.

5) Solubility of hyaluronic acid

Hyaluronic acid is highly safe and can not only be absorbed, but can also be dissolved using injectable hyaluronic acid enzymes. When too much hyaluronic acid is injected or the shaping is not good, hyaluronic acid enzymes can be used to dissolve it and restore it to its original shape.

Indications

Low nose: The nose bridge is low and flat, and the whole face lacks three-dimensional sense.

Saddle nose: The bridge of the nose and cartilage are mostly concave, and the nose tip is upward, shaped like a saddle.

Straight nose: The height of the nose bridge is acceptable, but the shape is straight and lacks the proper tapered feeling.

Drooping nose: The nose tip is drooping, and the highest point of the nose is located at the dorsum of the nose.

Nose with a low nose root: The nose root is low and flat, the nose is short and the proportions are unbalanced.

Wavy nose: The central axis of the nasal dorsum is not complete and smooth.

Horizontal Nostril: The nostrils are in the shape of "八", and the nose wings are wide and flat.

Operation Introduction

Hyaluronic acid is used as a filling material and is injected into the parts of the nose that need improvement via injection. Before the hyaluronic acid hardens, the doctor's skillful hands will pinch the nose into the shape you want. You should be fully prepared mentally before having hyaluronic acid rhinoplasty. You can choose a trusted medical institution or doctor to have the surgery, eliminate the fear of surgery, be full of confidence and security, and be calm and actively cooperate with the doctor. Do not seek medical treatment blindly to avoid adverse consequences. It is best to take a shower the day before hyaluronic acid rhinoplasty. On the day of surgery, you should use soap to wash off the dirt and grease on your face before going to the operating table to minimize the number of bacteria. You should also trim your nose hair and clean your nasal cavity before surgery. If the patient has other diseases before surgery, resulting in low immunity, it is easy for the surgery to cause infection and affect wound healing. Before performing hyaluronic acid rhinoplasty, there must not be any (bacterial) lesions on the face: such as folliculitis, furuncle, acne, acute eye inflammation, sinusitis, rhinitis, nasal vestibule furuncle, etc. Women should not undergo hyaluronic acid rhinoplasty during menstruation to avoid postoperative infection. Before undergoing hyaluronic acid rhinoplasty, you should fully understand the relevant knowledge about rhinoplasty, read relevant books, and it is best to visit people who have undergone hyaluronic acid rhinoplasty. You should be familiar with the entire process of hyaluronic acid rhinoplasty.

Operation process

The hyaluronic acid injection rhinoplasty process can be completed through three steps: hardware selection, anesthesia, and shaping. During the rhinoplasty process, you must choose a sterile operating room for hyaluronic acid injection rhinoplasty. The sterile management of the operating room directly affects the safety of the process and the recovery of the effect. The anesthesia required for rhinoplasty is only local anesthesia. If some people are sensitive to anesthesia, intravenous anesthesia can be added. I would like to remind everyone that the doctor’s aesthetics and techniques are very important factors. Before the hyaluronic acid hardens, the doctor's skillful hands can pinch out the nose shape you want, so that the nose shape can be sculpted in time. Otherwise, the hyaluronic acid will quickly solidify inside the nose, which will have a certain impact on the shaping effect.

Specifically, it can be divided into the following specific steps:

1. Clean the treatment area for 1-2 minutes.

2. Apply topical anesthetic to the treatment area and wait for 15 minutes.

3. Disinfect the treatment area for 1-2 minutes.

4. Injection, 15-30 minutes.

5. After the injection is completed, the doctor will evenly massage and squeeze the injection site to create the desired nose shape for 3-5 minutes.

Postoperative precautions

1. In order to keep the shape fixed within 24 hours after injection, avoid touching the injection area.

2. Do not apply ice or heat to the injection site.

3. Avoid strenuous exercise within a short period of time after the injection.

4. Maintain general basic care procedures after injection and do not massage the treatment area specifically.

5. Avoid sauna for one week after the injection.

6. Try to avoid taking aspirin or other similar blood-activating and blood-stasis-removing drugs one week after the injection.
