Will the expanded tissue get infected again after a few years?

No one can guarantee this, nothing is absolute. Any implant may cause infection. Don't rely on luck, get regular checkups to prevent infection. All surgeries have risks. If there is no problem with the implanted prosthesis, there is no need to replace it. However, if there is a problem with the prosthesis, it should be replaced in time.

There is a risk of infection early in any surgery. Silicone rhinoplasty may cause infection in the later stages, but only expanded polytetrafluoroethylene and autologous cartilage will not cause infection in the later stages. The early stage refers to the period from surgery to the time when the incision is truly healed. If it does not heal for a long time or ruptures in a short time, it is an infection. Infection after the wound has completely healed is a late infection.

1. No prosthesis can last forever on the nose. It is best to replace it every 5 to 10 years. Is this true?

Answer: Whether it is a silicone prosthesis or expanded polytetrafluoroethylene, you can keep it as long as there is no problem. You must replace it every 5 to 10 years. Removing the expanded tissue is not a difficult task for an experienced doctor.

2. Is the long-term infection rate of expanded polytetrafluoroethylene very high? Is it difficult to remove?

Answer: According to the literature I have seen and my experience, the infection rate of expanded polytetrafluoroethylene should be around 3%. Of course, this infection rate is also closely related to the surgical environment and the doctor's operation. That is to say, these 3% infections mostly occur when the operating room's sterile environment is poor or the doctor's operation is incorrect. If babies can ensure that they find institutions with good conditions and doctors who operate regularly, they can completely avoid infection problems. As for removal, as I said just now, removing the expanded polytetrafluoroethylene is not a difficult task for an experienced doctor. So even if the expanded polytetrafluoroethylene has problems such as infection, there is no need to worry. You can find a good doctor to solve the problem for you.

3. In the United States, Japan, South Korea, Thailand, and Singapore, except for a few doctors who use expanded polytetrafluoroethylene, the vast majority of doctors use silicone prostheses. In recent years, many manufacturers in the world that originally produced expanded polytetrafluoroethylene have stopped producing it. The reason is self-evident?

4. Answer: Europeans and Americans seldom use prosthetic rhinoplasty, which is basically determined by racial characteristics. Europeans and Americans rarely have low noses, so there is not much demand for rhinoplasty, and the noses that need to be raised are also very small. Basically, only a small amount of cartilage can fully solve the problem. In addition, the nose skin of Europeans and Americans is softer and thinner than that of Asians, so it is usually not easy to use prostheses. Compared with Europeans and Americans, Asians need a lot of augmentation, but the autologous cartilage available for the nose is limited (it may not even be enough for the tip of the nose), so basically they need to use prostheses.
