Hi everyone I'm new here and have soooo many questions. A little bit about my situation... Had surgery on May 24, 2012 to remove the tumor on my inner cheek, right neck dissection to remove lymph nodes and skin graft from my right thigh. 30 treatments of radiation and 3 treatments of Cisplatin. (Awful stuff.) My question is I developed trismus from my surgery and was wondering if I will be able to open my jaw all the way again. I've been to the speech therapist and am doing all the excersises she told me to do. It has gotten a little better but still not all the way. Very hard to get a spoonful or forkful of food in there. One other question I have is about the pain. I'm still having pain in my cheek, along my jawline and where the incision is. My ENT said everything looks okay and is healing great. Just was curious if the pain is normal and will that go away as well? Would love any input on my questions I have. Thanks so much!

Having worked in the dental field for 16 years before I had kids I knew about trismus and I was careful to do my exercises throughout treatment. Even though I did them religiously I ended up with a slight case of it. Thru therapy and time it has gotten much better. Just keep doing them and you should be able to recover most if not all of your ability to open all the way. Ugh radiation...what wonderful things it brings to us!
Good luck to you.

I have trismus too (didn't have surgery), and seemed to be making progress through exercises...
have had minor throat pain pretty much straight through, but recently (about 3 weeks ago, roughly 4 months out from tx) woke up one morning with jaw swelling, increased pain, and worse trismus.
oncologist was on two-week vacation, so I went to ENT. she found a lot of necrosis in throat and did a biopsy. biospy was negative for the portion of the necrosis that she could get at.
oncologist came back, said the necrosis was normal and nothing to worry about. he thinks maybe the swelling and pain were because I injured the muscle with exercises. I didn't really buy that, but had no other explanation for setback.

and last few days, I'm starting to feel better again. swelling and pain are down. so guess I've gotta go with injury.
minor pain was my normal, until the little scare described above. that sure didn't seem normal.
don't hurt yourself with exercises.

I have had this since my surgery, chemo, and rad back in 1978. I did many exercises to try to help but never able to get it back open fully, just had to smash my big macs to eat. My most recent rad ending in July has tighten up my jaw to the point I can get a finger or two in mouth at the most. I still do exercises daily to try to help, so just have to take it a day at a time, and hope it loosens up.

I also have a hard time opening my jaw all the way. Sometimes it is better than others but I do exercises each day - open my mouth slowly as wide as I can and then close it. I think I will always deal with this. The other is the pain tingling in the side of my face near my incision. My surgeon had to cut the nerve that gives feeling to my ear and the nerves in my face were also somewhat damaged. I have no real feeling in that side of my face and none in my ear. However, when I touch or am touched on that side near the incision site, I could scream. It is still very sensitive to touch, almost like being scratch by an animal I would think. I think what you are experiencing is "normal" considering what you have been through. I hope it gets better for you!
