Okay, I'm not saying I'm agreeing with any of this but talked to a max fac today, very well known, also a professor at a top hospital --said that HA paste doesn't do much and is really just a way to pad A LOT of extra money. I don't know it's an irresponsible thing to say or what, but I've heard that twice now, since the things A/G use HA paste for can be done with other materials that are very cheap. I really don't know what to say about it though. Some of Mommaerts' patients have had to it to augment jaw angles and whatnot and they've ended up with asymmetries they were complaining about so who knows...
