(Sorry for the multiple postings....I don't know what I did....pushed the wrong button, I guess)..
Two things....at the end of my post, I meant to say that the upper jaw is easier to work with as far as surgery goes, and that the cancer on the upper part of the mouth is easier to eliminate than the cancer in other areas. At least that's what I was told, and I choose to believe it!
I re-read your post, and you don't mention that you will have part of your jaw removed. Is your lesion limited to the hard palate? Having natural teeth all around would be a great help in securing your obturator.
Let me know more about your situation, and maybe I can add a bit more detail.
I see that you are from Knoxville, TN. I, myself, am a native of Memphis.
