Just use cartilage, your own ear cartilage. I did it in Boya last year, and I did it in Ogilvy a long time ago. Later, I heard that there were great side effects. Last year, I went there to have Ogilvy, then I had a nose pad and a rhinoplasty, and I recovered quickly. The three-dimensional sense of my nose came out when I took out the stitches. It's been a year now, and it's recovering well.
