The best nasal implant is your own cartilage. Among synthetic implants both Gore-tex and silicone can be used. Silicone is available in many shapes and sizes to achieve different results depending upon the patient's anatomy. This tends to be most effective in patients with thicker skin but still has the risk of infection and extrusion. Gore-tex tends to be best used for augmentation of the nasal bridge where sheets of Gore-tex can be layered to provide precise and stable augmentation of the profile of the nose. Again, infection is a risk with any synthetic implant but there is typically an acceptable low risk if Gore-tex is properly placed. I hope this information is helpful.
Both products may be used for augmentation of the nasal bridge during Rhinoplasty Surgery, and the choice depends on both the experience of your surgeon, and your ethnicity. Silicone nasal implants are most commonly used in Asian patients, or other ethnic patients with thick skin. ePTFE implants are my personal preference for most patients requesting dorsal nasal augmentation. Both products are safe, but have a risk of infection and extrusion over a lifetime: approximately 3-5%. Hope this is helpful for you. Dr. Joseph
