Information on materials I learned while going around getting rhinoplasty

To get rhinoplasty and raise the tip of the nose, you ultimately
 have to use costal cartilage, ear cartilage, septal cartilage, terminal cartilage, etc.
 
I've had consultations at over 20 places,
 and the most famous rhinoplasty director in Korea, who is from Seonggol, said that the reason he doesn't use donated ribs after doing the surgery for a long time
 is because the rate of problems after the surgery due to calcification or incompatibility is high, so he only uses his own ribs. And
 
after hearing that, he discarded the donated ribs right away,
 referring to the calcification . Depending on the level of glamour you want, that is, the height of the nose tip, you can cover 2-3mm with ear and septal cartilage. To
 raise it a little more, you have to scrape off the septum or costal cartilage for more than 3mm.
 
I'm even looking at terminal cartilage these days because I'm interested in it... I don't want to peel off my own ribs;;
