I'm curious about the cartilage protrusion at the tip of my nose.

<여기동그라미친곳이야>

<This place is crazy>It's been about 1 year and 4 months since I had a nose surgery. I put silicone in the bridge of my nose with donated costal cartilage and
 ear cartilage
. First of all, the ear cartilage is round and transparent, but
 when you touch both edges of the visible ear cartilage (the circled areas),
 are they sharp? I can feel it and
 wonder if that could be silicone and not ear cartilage???
 
I heard that the ear cartilage doesn't break through, but the circular area felt very sharp to the touch,
 
so I looked it up and found out that it was because the ear cartilage was gently trimmed when trimming it. Is there a possibility that it breaks through?
 It doesn't show up well in the picture,
 so the answer is to ask a doctor, but like me, it doesn't show up well. I'm asking because I wonder if there was anyone there.
