Silicone implants can become “displaced” or “migrate”, meaning they can move. The possible danger to your health would be from the risk of extrusion (of the implant thinning your skin to the point of ulcerating through) and the risk of infection. Signs that this is occurring include redness and tenderness along the nose where the implant is. Unless either of these is happening, your health is not at imminent risk, though at some point the implant will have to be removed. When an silicone or Goretex implant has been placed in the nose, it may be removed and replaced with your own cartilage simultaneously during revision Asian rhinoplasty as long as there is no active infection, and the skin is completely intact.
