I would want to know how much tongue they are planning to remove. It sounds like your tumor is near where mine was. I had a skin graft from my thigh. Not really to rebuild the tongue, but to keep it from healing to the floor of my mouth. This helped maintain mobility. Maybe that is what your surgeon is planning? I've had three surgeries on my tongue. The first two removed pretty small areas and did not really affect the use of my tongue or my speech once I'd healed. The last one took about 1/6 of my tongue. The tip is permanently numb and I have a bit of a lisp. How much tongue they take will depend on the size and depth of your tumor. If yours is small and superficial, the surgery will probably be pretty minor. Definitely talk to your surgeon and find out what his plan is. I would also want to know how much experience he has and what complications could occur.
