Good luck with your surgery! I'll be having mine tomorrow too. Twice the anesthesiologist had to intubate me through the nostrils due to trismus. I was also scheduled for a MRND my first dissection, and they had to do a radical due to everything being all twisted up from prior radiation. Even with that I was still able to lift my arms overhead, after healing, until later surgeries and additional radiation. Sometimes the stitches are kept in longer in the radiated tissue due to delayed healing, sometimes 2 weeks longer than the usual 7.
