Hello, If you are only unhappy with the bridge of your nose, cannot get glasses to fit, ect, there are 2 options. 1) Nonsurgical rhinoplasty. In the office injectable fillers like Juvederm or Radiesse can be placed along the bridge of your nose to add height. There is no real downtime, it is economical, and the fillers last about a +/- year. 2) Limited rhinoplasty: If you are only concerned with the bridge of your nose a limited rhinoplasty can be performed to place a graft to increase the height of the nasal bridge. Cartilage, silicone and gortex all have the same longevity in that they are all considered permanent. All three grafts are frequently used to augment the bridge of the nose. If you ask 10 different surgeons you will get 10 different opinions on which material is the absolute best choice and why you should avoid the other two. I believe them all to be acceptable options that can lead to good results. Silicone implants come presized and Gortex needs to be sculpted by the surgeon. Both are synthetic and have the potential for infection. That being said, hip replacements, heart valves, and hundreds of other implants are safely and reliably used throughout the body. Cartilage has less risk of infection, needs to be expertly sculpted, and his the risk of warping over time. Because there is no clear best option all three grafts are routinely used and your surgeon will likely have a preference for one. Hope this helps
