I had TORS robotic surgery April 2023 which included right neck dissection with all lymph nodes removed as cancer had spread to a couple of lymph nodes. The TORS surgery was to remove primary tumor of 3cm at base of tongue. The Neck contains many nerves which are cut or disrupted during the dissection. One major one will effect raising the arm or shoulder. I was fortunate and did not have any issues with either. However, I was pretty much totally numb on my entire jaw/neck leading up to my ear and side of my skull above the ear. I also had lip drop on my mouth which caused me to use a hand to "open" my mouth while eating for a few weeks. OK.. the Good news. As of today about 18 months out I am mostly healed with little to no lingering issues. If your surgery is today I know you will have a difficult week but hang in there as things will improve greatly.
