What is the difference between a personal and cadaver rib graft? Is there a contrast between complications associated with both?

For my revision rhinoplasty I May need rib Cartilage to rebuild my bridge my biggest fear is the complications that come about itwith it. Is there really no difference between the two? I feel many are using cadaver rib and saying it’s the same as your own personal rib? I read that rib has lesser resporption rate? What are chances of infection or warping or rib moving out of place, how common are these complications?
