I do have a question. Dad has just started saying that he can't open his mouth all the way. This is a recent development, within the last day or so. He had his mandiblectomy surgery two weeks ago. I've read a little bit about triasmis and how difficult it is to treat. Is that what this is? We met with his reconstructive surgeon just yesterday. Dad noticed the difficulty when the surgeon was inspecting his flap. We asked if we should be doing exercises with his jaw, and the surgeon said it was normal to feel a little tightness and discomfort when opening his mouth, and to give it some time yet. What are your thoughts? Did you do exercises after your mandiblectomy? How soon did you start?
