I don't blame you at all for having inconsistent thoughts about this. You're in the thick of it, with a pretty significant complication (that I think no one here has gone through, nor hopes to go through) and it's always harder to think about your own case clearly and let alone after a complication. Your thoughts will be back and forth as you try work this out. Your decision is also time sensitive, which makes it so much harder.
If considering maxilla, definitely ask your surgeon about preventing future relapse. I mean, how can they be sure it won't happen all over again?
