Rhinoplasty is increasingly becoming a beauty trend of women when they want to own a high and delicate nose shape in harmony with the face.

Currently on the market there are many materials and methods of rhinoplasty. Then to learn about the most popular rhinoplasty materials today, VOH Online had an interview with plastic surgeon Nguyen Quoc Dinh - Head of Saigon Lotus Plastic Surgery Department.

*VOH: Doctor, currently on the cosmetic market there are many different materials used to lift the nose, so how many popular types of cartilage are there?

Doctor Nguyen Quoc Dinh: Currently, there are 2 groups of materials commonly used in rhinoplasty, which are the group of artificial materials and the group of autologous materials, in addition, there are allogeneic implant materials such as donated rib cartilage, dermis, muscle scales.. but rarely used. There are differences between the two groups, even materials within the same group still have very unique properties.

*VOH: The doctor can share more about each material as well as the advantages and disadvantages of each. With the group of artificial materials, what are the characteristics , sir?

Doctor Nguyen Quoc Dinh: Artificial materials are also divided into the group of materials used to improve the bridge of the nose and the group of materials to support shaping the tip of the nose.

General advantages of man-made materials:

• Safe, harmless can stay in the body forever

• Easy to cut according to customer's nose

• Abundant, available, "preliminary" supply

• Thereby shortening the surgery time

The common disadvantages of artificial materials are material exposure, rejection, irritation, infection, etc.

Although this rate is very low, only about 1-2% and is not worrisome, it can still happen if you choose a reputable cosmetic facility, the doctor is not qualified and the environment is not enough. Surgery is not guaranteed.

*VOH: Can you tell me more about artificial materials used to improve rhinoplasty?

Doctor Nguyen Quoc Dinh: Rhinoplasty materials often use synthetic polymers such as Silicon and ePTFE (Surgiform, GoreTex, Nanoform)

In which the most popular and oldest is silicon material, after many improvements, silicone cartilage has gradually become more complete and is capable of remaining in the human body for a certain period of time (depending on the location of the body). ) without complications.

In addition, this type of cartilage also helps to create a soft and beautiful natural nose shape thanks to the flexibility of the silicone material, so it is easy to cut into many different shapes and sizes. However, in addition to the advantages, this type of cartilage also has many limitations such as: easy to cause nose bridge to drop, create pressure causing red ball of nose tip due to relatively heavy cartilage, easy to encounter dislocation, irritation because it is not has high adhesion. Because blood vessels and tissues are difficult to adhere to, over time, silicone cartilage will cause fibrous capsule in the surrounding areas. Cartilage is easy to irritate people with sensitive terrain.

There are other types of cartilage Surgiform, GoreTex, Nanoform. This is a type of cartilage made of 100% ePTFE material, which has been tested by the Food and Drug Administration (FDA) for quality, certified for safety and effectiveness. In particular, this high-grade artificial biological cartilage has millions of microscopic holes to allow blood vessels and surrounding organizations to penetrate. This is a safe material in the medical and aesthetic fields used to make artificial blood vessels.

This type of cartilage has a soft, malleable texture, reduces the risk of contact or abrasion of the skin and bones, in the long run with the ability to adhere to tissues, contributing to a tighter attachment to the nasal structure, does not cause symptoms. distorted, wobbly, contributing to a high and elegant nose shape, the risk of exposing the bridge of the nose is lower. The good adhesion of the material to the autologous tissue is an advantage, but it is also a disadvantage when it is necessary to remove, correct or type the filler, if it is unfortunately deviated to need correction, it will be more difficult to remove and potentially shrinkage or change over time.

In addition, less popular is Sili-tex, Gore-sili this material is a combination of Silicon and ePTFE (Goretex) which is very promising in the future, but it is still new, there are not many studies on the degree of strength. safety and effectiveness as well as the doctor's experience.

*VOH: So what is the structure of cartilage itself, as well as advantages and disadvantages, doctor?

Doctor Nguyen Quoc Dinh: If we talk about autologous cartilage, there are 4 types of autologous cartilage such as: costal cartilage, ear cartilage, septum cartilage, temporal muscle fascia. However, the two types of cartilage that Asians use most often are temporal fascia and auricular cartilage.

The most commonly used is auricular cartilage, this is a dissection technique, taking 1-2 cm of ear cartilage to cover the tip of the nose and using artificial cartilage to raise the bridge of the nose. The ear cartilage is usually located in a relatively easy position to dissect compared to the costal cartilage.

About the temporalis fascia, this is a thin layer of white cells, wrapped around the muscle layers under the skin in the temporal area. This type of cartilage is easy to take, soft and easy to shape, so it is especially suitable for covering the tip of the nose.

And rib cartilage is the optimal method that can solve all nose problems, even those with severe complications or trauma, that no conventional rhinoplasty method can solve. The rib cartilage used to lift the nose is the end cartilage of the 6th or 7th rib. The rib cartilage has a prominent feature that is quite hard, straight, and firm.

In addition, rhinoplasty is a very complicated technique, requiring a highly specialized and experienced doctor to extract the rib cartilage and implant it in the nose in the safest way.

The other type of cartilage is less common with Asians, because the Asian septal cartilage is quite weak, so it is rarely used. The septum cartilage is located in the nasal cavity, which is the cartilage that separates the two nostrils. During rhinoplasty, the doctor will use a part of the septum cartilage to make grafts to help build a solid nose base, and at the same time, lengthen and raise the tip of the nose to help create a more beautiful and natural nose area.

Most of these autologous cartilages have the advantage of high compatibility, bringing a beautiful natural nose shape and minimizing medical problems. But in addition to advantages, it also has disadvantages such as: because it is autologous cartilage, after a while it will be destroyed, for example, 100% of the nose, after a while, it will be about 80%.

*VOH: Can you tell me which type of cartilage is the best out of all the above?

Doctor Nguyen Quoc Dinh: In fact, there is no best type of cartilage, only the most suitable type of cartilage. Because the needs and situation of each customer is different, it will depend on that to choose the best improvement plan.

But if talking about the most optimal type of cartilage that can solve all defects, even the most difficult nose case is the rib cartilage.
