Implants for an Asian rhinoplasty

Silicone implant palpable?
Contrary to popular belief, it is actually quite normal to feel the implant no matter what shape it is, though it is less likely with the short "I"shape. It is only likely to extrude if you can see the implant reflecting shadow through a thin skin. Even so, the chance of extrusion is less than 10%.
Silicone Implant in the Nose
It is not unusual for Asian rhinoplasty patients to feel the silicone implant, especially with L shape implants where the elbow of the implant is in the tip region. This does not necessarily mean the implant will extrude. Hopefully you have sufficient tip skin thickness that allows some cushioning in the presence of the implant. It is hard to say what chances you have of avoiding a revision procedure. You should touch base with your surgeon to make sure they don't have any ongoing or evolving concerns. Happy healing.
