Hi @blondeboss It's called Osteoradionecrosis or bone death due to radiation. I hope that isn't the case with your husband but if it is, there is a fix for that, of course. Not a fun fix but here I sit now almost five years out eating corn on the cob with a smile albeit a bit of a pirate smile. I wrote about this with this link: https://connect.mayoclinic.org/discussion/mandible-reconstruction-with-fibula-free-flap-is-this-an-option/
Cancer is the gift that keeps on giving, whether you want it or not.
All I will tell you is to make double sure your surgical team is well versed in this complex operation. It takes several weeks to work up the procedure specific to each patient. You likely would need to travel to a large clinic or hospital somewhere to have this done. For me the choice of Mayo Clinic was due primarily because the Mayo team has trained other teams around the world in this and has likely the most experience. In addition, they were great in all areas, so great that here I am still volunteering help in this area on Connect.
Any questions please don't hesitate to ask. Courage.
