The difference between expanded polytetrafluoroethylene rhinoplasty and silicone

With the rapid development of medical technology, plastic surgery is also developing rapidly. Prosthetic rhinoplasty is made of either silicone or expanded polytetrafluoroethylene. Both are used in rhinoplasty. However, in many cases, we confuse the two when choosing rhinoplasty. Therefore, in order not to affect the effect after the operation, it is important for us to understand the difference between the two. The following is a detailed introduction to the difference between expanded polytetrafluoroethylene rhinoplasty and silicone.

Silicone Rhinoplasty

The surface of the silicone rhinoplasty material is frosted or smooth, so after the silicone rhinoplasty is placed into the nasal cavity, there will be a process of encapsulation and fusion between it and the soft tissue. However, when the silicone prosthesis has not yet completely formed a capsule, the prosthesis can easily be affected by external gravity, causing the prosthesis to shake left and right and shift after surgery. So is expanded polytetrafluoroethylene rhinoplasty better or silicone polytetrafluoroethylene rhinoplasty better? From the perspective of prosthesis compatibility, expanded polytetrafluoroethylene rhinoplasty is better.

Expanded polytetrafluoroethylene rhinoplasty

Expanded polytetrafluoroethylene is used for rhinoplasty, and this material was originally used for clinical human implants, so its molecular stability is very high. In addition, it has a certain elasticity and super high softness. Therefore, no matter how long the expanded polytetrafluoroethylene is placed, the prosthesis will not age or deform.

There are many kinds of silicone molecules used in silicone rhinoplasty, so they are also divided into domestic, joint venture and imported ones. Among these three types, domestic silicone prostheses are the hardest and have no elasticity at all. In addition, due to the poor craftsmanship and molecular stability of domestic silicone prostheses, they will generally age or deform 5 or 6 years after implantation, and will need to be removed in 10 years at most. At present, the silicone produced by the joint venture can last for about 30-40 years. As for the imported ones, after current research, they can still be kept in the body for life.

Expanded polytetrafluoroethylene rhinoplasty

Although the surface micropores of expanded polytetrafluoroethylene rhinoplasty can achieve good tissue compatibility, it also has certain risk factors. The expanded polytetrafluoroethylene is initially placed in a sterile packaging box, and the doctor must take out the expanded polytetrafluoroethylene during surgery and then sculpt it according to the individual's nasal condition. If the carving time is too long, the small pores of the expanded polytetrafluoroethylene will absorb a lot of dust in the air. When the prosthesis is placed in, bacteria will breed in the nasal cavity and cause infection. After rhinoplasty with expanded polytetrafluoroethylene, if you are not satisfied or other problems arise, the prosthesis needs to be removed. However, since the soft tissue and the expanded polytetrafluoroethylene capsule are too tight, it will be troublesome to remove it and cause greater damage.

Silicone Rhinoplasty

After silicone rhinoplasty, although the time it takes for the nasal prosthesis to form a capsule and fixate is relatively long, if there are any unsatisfactory conditions or other problems after the surgery, the silicone prosthesis can be easily removed during the operation. This is also due to the fact that its surface is frosted and glossy. Therefore, when silicone is taken out, it can damage too much soft tissue and cause excessive damage. And after the silicone prosthesis is removed, if you want to repair it immediately, the silicone prosthesis can be reused as long as it is confirmed that there is no infection or inflammation. However, this cannot be done with expanded polytetrafluoroethylene, because it has micropores and may become infected. So which is better, expanded polytetrafluoroethylene rhinoplasty or silicone rhinoplasty? From the perspective of solving subsequent problems, silicone rhinoplasty is better.
