Hi, Noor -

Even if you can't get something like the Therabite, you can use your thumb from one hand and forefinger from the other to hold your mouth open for stretching. I, too, had a maxillectomy, and must stretch every day to keep my jaw from being constricted by scarring. Just hold seven seconds each time, repeat seven times, do seven sets per day (that's one way to do it)!

Good luck with everything. You will find tons of great information on this website for sharing with others!
