Glad you got some answers. As far as the split mandible for surgery - it was presented to me as a possibility but since I was having a bilateral neck dissection, there was the possibility that they would be able to do the tongue resection and reconstruction through my neck, and that's what happened. So, depending on where your tumor is and if you're having the neck dissection, I would ask your ENT if that's a possibility - one less thing to heal from.
