My surgeon mentioned all these as graft materials for my genioplasty.
He says that a graft is necessary for stability + to make sure the gap doesnt fill with fibrous scar tissue ( never even heard this mentioned anywhere online ).
I told him that I dont want the gap to be filled with my own bone when it heals, not a foreign material ( he suggested medpor ). He told me even if they used my own hip bone that the bone in the gap would still have a different bone density than my original chin bone, which I guess is acceptable.
I want to maximize the likelihood that my own bone fills the gap created from genioplasty, is my surgeon just trying to aware me on possible side effects or are these actually common complications?
