You know, I've been going to meetings and hearing papers on breast implants and breast reconstruction for 30 years. There's never been a consensus on anything. In fact, different surgeons will argue for different implant types.
Again, we just don't have enough data to make sweeping cases for that. There are certain body types that seem to lend themselves to certain localized complications, but these big things that we don't really know about seem to be random.
