What are the differences between silicone and expanded polytetrafluoroethylene?

Everyone has heard of silicone. Silicone is also called silicic acid gel. It is an adsorptive material whose main component is silicon dioxide. This substance has a major characteristic, that is, its chemical properties are very stable, so it has high medical value. For example, silicone can be used to make prostheses, breast prostheses, etc. So what is the difference between silicone and expanded polytetrafluoroethylene?

First, the difference between expanded polytetrafluoroethylene rhinoplasty and silicone rhinoplasty materials

Expanded polytetrafluoroethylene is a microporous structure of polytetrafluoroethylene material

Expanded polytetrafluoroethylene is a special polytetrafluoroethylene material. It has a soft and elastic texture and has very good human compatibility like silicone. It is also non-carcinogenic and non-allergenic. Its biggest feature is the micropores on its surface, in which human tissues and blood vessels can grow and form connections, which are just like autologous tissues. Therefore, from a medical perspective, it is currently the most ideal tissue substitute and can also be used to manufacture artificial blood vessels.

Silicone rhinoplasty is a medical silicone rubber material

Silicone prosthesis is a special medical silicone rubber product and a medical silicone polymer material. Its characteristics are resistance to high and low temperatures, stable chemical properties, good compatibility with the human body, non-toxicity, non-carcinogenicity, and non-sensitization. This material is not only used in cosmetic plastic surgery, but also in other clinical surgeries. That is to say, it can not only be used as a prosthesis to raise your nose, but also can reconstruct other organs of the body, and even artificial blood vessels, artificial hearts, etc.

Second, which is better, expanded polytetrafluoroethylene rhinoplasty or silicone rhinoplasty?

Expanded polytetrafluoroethylene rhinoplasty and silicone rhinoplasty use two prosthetic materials, expanded polytetrafluoroethylene and silicone. In essence, there is no so-called superiority or inferiority between these two materials. They are both safe and excellent prosthetic materials that have been proven through long-term practice. Today we will compare these two materials from the perspectives of expanded polytetrafluoroethylene rhinoplasty and silicone rhinoplasty, including their materials, effects, infection rates, and removal rates.

Third, the difference between silicone expansion

Both silicone and expanded polytetrafluoroethylene are medical prosthetic materials. Silicone prosthetic materials have a basically formed shape and can be used with slight modifications based on each person's situation. They are easy to implant and even easier to remove. In the event of infection, rejection, etc., they can be removed completely and early without leaving any hidden dangers. Therefore, this material is currently the most widely used prosthetic material in the world. Compared with silicone, expanded polytetrafluoroethylene is more realistic when used for rhinoplasty and other procedures, and has better compatibility with tissues. However, it is more expensive and has very high requirements for the doctors performing the surgery. During the operation, care must be taken to strictly prevent the occurrence of infection. The infection of expanded polytetrafluoroethylene is divided into short-term postoperative infection and long-term infection. If the infection occurs within half a month after the operation, it means that the doctor's aseptic operation during the operation is not strict enough. As long as the doctor strictly follows the aseptic principles during the operation, the postoperative wound is carefully sutured, the sutures are removed after the operation, and the dressing and care after the sutures are removed are careful, the infection can be avoided.
