Peace
there's always hope..don't ever give that to the Beast. I had my jaw removed and rebuilt with titanium and fibula. Thankfully, I've have no issues at all.
I have no idea whether they would try another recontruction of your jaw or not. If they don't, there is still lots to life that needs to be lived, and it doesnt depend on eating the way you used to.
I'm not sure what you mean by "old fashioned" though. the micro-vascular work involved with mandible reconstruction and donor bone is by no means old fashioned. It's only been in the past decade or so that it's even been possible. Beoyond that, the solution often was to simply remove the jaw completely; there just wasn't much else they could do.
Have you talked to the surgeons about future restorative work? I would want to exhaust every possibility in that regard
