Is there a risk of infection with expanded polytetrafluoroethylene (ePTFE) nasal augmentation?

Generally, if the surgical instruments and the implantation area are thoroughly sterilized during expanded polytetrafluoroethylene (ePTFE) rhinoplasty, and proper post-operative care is followed, infection is unlikely to occur. However, if sterilization is inadequate or post-operative care instructions are not properly followed, infection may develop. During ePTFE rhinoplasty, an incision is made inside the nasal cavity, and a porous ePTFE material is implanted as a prosthesis to augment the nasal bridge and improve nasal contour, after which the incision is sutured. The typical reference price for this procedure ranges from 8,000 to 20,000 yuan, with noticeable improvement generally seen within one to two weeks. This procedure should be performed at a正规 hospital. A detailed explanation is as follows:

If the surgeon thoroughly sterilizes the surgical instruments, ePTFE material, and surgical area and strictly follows aseptic techniques before the procedure, the risk of post-operative infection can be significantly reduced. Additionally, if the patient strictly follows the surgeon's post-operative care instructions—such as avoiding touching the surgical site with hands and keeping the wound clean and dry—infection after ePTFE rhinoplasty generally does not occur.

However, if sterilization is incomplete or the patient neglects post-operative care—for example, frequently touching the surgical site with hands, coming into contact with contaminants, or failing to take prescribed antibiotics on time—infection may occur after ePTFE rhinoplasty. Infection can lead to symptoms such as redness, swelling, pain, and pus discharge at the surgical site, and may compromise the stability and effectiveness of the ePTFE implant. In severe cases, removal of the implant may be required for treatment.

To ensure the safety and effectiveness of the surgery, patients should adequately prepare and undergo appropriate pre-operative evaluation. Additionally, post-operative care and recovery should be carefully managed to prevent complications such as infection.
