I-shape versus L-shape silicone implants for Asian rhinoplasty- is it possible for cartilage to extrude?

While L-shape implants have a greater risk of extrusion through the skin in the tip of the nose, I-shape implants still carry a higher risk of extrusion through the skin in the bridge of the nose than autologous grafts (your own cartilage).  Cartilage has an infinitely lower chance of extrusion than synthetic grafts (practically none under normal conditions), and a much lower risk of infection or migration.  Overall, autologous grafts are a much more permanent and safer option for reshaping the nose during Asian rhinoplasty.    

We do not recommend L-shaped strut silicone implants placed in the nose due to the problems we have seen with them. For Asian rhinoplasty, we will use a Flowers nasal dorsal Silastic implants manufactured by Implantech. Any synthetic implant can protrude if the implant itself was too big for the skin  envelope. It's rare to ever see a cartilage grafts extrude.   Rhinoplasty is a difficult  endeavor,  So choose your Surgeon  wisely based on extensive experience.

Hello chai and thank you for the question.  In short, yes silicone implants can extrude and cause a lot of problems. For the most part Asian rhinoplasty involves building the bridge up to give better definition. A variety of implants have been used for this purpose. I personally do not use such implants in my practice as I have seen numerous disasters relating to their infection and subsequent extrusion, thus requiring me to remove them and treat the "so-called" aftermath. This can occur many months after the original surgery and for the most part these patients were operated on in Asian countries (especially South Korea). Many surgeons like working with such implants because they are quick to place and provide good results in select patients. I personally will only use native cartilage or other tissue to build up the dorsum. The silicone implants tend to form a capsule and become mobile in the nose as they never truly get integrated into the tissues as grafts from your own nose or rib would.  Hopefully this information helps.
