Hi Doc,
I was 65 when I had my mandiblectomy surgery. I understand the reluctance as I worked it out in my head for about two months. I think what sold me on the surgery was the idea of not having the surgery, having a fracture of the mandible, which then becomes an emergency or worse. However, after going through cancer treatments years before, I realized the healing would be faster and likely far fewer side effects. While a bit more involved than a BHR hip surgery, I found the entire process agreeable. It also results in a great story when the scars are discovered. And to make a shameless plug, I had this done at Mayo Clinic Rochester by a surgery team that has trained others in this procedure worldwide. I went forth with little worry, resultant successful and quickly became an advocate for this surgery, complex as it is.
I wish you well sir. That future day when you bite into a fresh ear of corn without pain or worry, don't be surprised if tears of joy soon follow.
