Introduction
Which is better between rhinoplasty and silicone rhinoplasty depends on the specific application, as each has its own advantages and disadvantages. Silicone is a relatively inert biomaterial with good stability, easy to implant and remove, and provides better support. The biggest drawback is that when the skin is relatively thin—such as at the nasal root or nasal tip—or when the implant is placed too high, the skin may become even thinner and the implant could become exposed.
A high and well-defined nasal bridge is something every beauty-conscious individual desires. If the nasal bridge is flat or sunken, rhinoplasty can help improve its appearance. But which is better—expanded polytetrafluoroethylene (ePTFE, commonly known as "porous" or "soft tissue filler") or silicone?
ePTFE vs. Silicone for Rhinoplasty
Whether ePTFE or silicone is better for rhinoplasty depends on specific clinical applications, as each material has its own advantages and disadvantages. Silicone is a relatively inert biomaterial with good stability, easy placement, simple removal if needed, and strong structural support. Its biggest drawback is that in areas where the skin is thin—such as the nasal root or tip—or when a very high implant is used—the overlying skin may become even thinner over time, potentially leading to implant visibility or extrusion.
ePTFE is a porous biomaterial that allows host tissue ingrowth, enabling it to integrate more naturally with the body. However, it is more difficult to place and remove, and offers relatively weaker mechanical support. Its most significant disadvantage is a higher risk of infection compared to silicone. Clinically, the choice between ePTFE and silicone should be based on the patient’s individual nasal anatomy and condition to achieve optimal aesthetic outcomes.
Before undergoing rhinoplasty, patients should ensure there are no signs of local infection or cold symptoms. Women should avoid surgery during menstruation or pregnancy. The face should be thoroughly cleansed without any residual cosmetics. It's important to fully understand basic knowledge about rhinoplasty and the surgical procedure, and to prepare accordingly. After surgery, keep the wound area clean and dry. Avoid getting the incision wet before suture removal. If there is blood crust or discharge, gently wipe with a cotton swab dipped in sterile saline solution, or visit the clinic for proper cleaning. Patients should avoid wearing glasses, massaging the nose, or exposing it to external impacts after surgery to prevent displacement of the implant. We hope this information helps you. Wishing you good health and happiness!
