Nasal silicone implant has I-type and L-type. However, the L-type is not often use recently.
Because L-type silicone often caused problem on nasal tip.
In Korea, I-type silicone use in nasal bridge, and nasal septum cartilage and ear cartilage use in nasal tip.
Merit is that it is easy to use since it comes in different shapes, size, and reduces operating time.
And it is also easy to remove.
Disadvantage is that it may cause infection, nasal contraction, or rejection reaction.
And it also has less bio-compatibility since tissue can not grow in.
