I used nasal septum + ear cartilage + silicone + donor rib
 for a little less than two months. Is this circled area showing
 cartilage or silicone?? ㅠㅠㅠ
 I don't know the difference between the two, so
 are there any examples that know more accurately what they are?

There is no pain or heat when I press it, and I sometimes feel it moving when I move my head or get up from lying down, and
 sometimes there is a throbbing sensation inside and out for about 30 seconds.
