Hi. I had SCC of the tonsil, etc., w/ a rad. neck dissection over 6 years ago. I didn't need speech therapy, but the swallowing, etc. really helped. Radiation will tighten up the jaw, etc. We do not even realize how we eat, we just do it. To open your mouth wide, you actually slide the jawbone forward, for example. Can't do that, can't eat a hot dog. I highly recommend any and all therapies. -Chuck
