I was diagnosed with lymphomia in my mouth. We initially thought it was TMJ related and by the time it was ruled out I could no longer open my mouth or swallow. No surgery was possible but have had radiation and chemo. I eat and drink using a g tube. I consulted with a nutritionist and prepare my own meals but do also use Ensure Plus. I'd be happy to share more details as to what works for me. My primary dinner is boiled chicken and vegetables in chicken broth. Bottom line is to count calories for your daily weight goal and to blend the right ratio of solids to liquids so that they will go through the tube. Good luck!
