Mrs W. -

I'm sure you've been inundated with details and suggestions about everything your husband has had to and will deal with in the very near future. So, I'm going to add one more!

The pain and frustration associated with the trismus will probably get worse during and after radiation. Try to encourage your husband to engage in static stretching of the jaw. I've found that by stacking tongue depressors and inserting them between the teeth worked best. If he has 22mm (almost an inch!) have him start at 16 depressors. (Tongue depressors are 1/16th inch thick face to face.) Insert and hold open the jaw open for 30 seconds. Repeat 8 times in succession once a day. Once the pain subsides at this height, add a depressor and repeat.

There are devices out there that accomplish the same thing and are probably more appropriate.
