All the very best for tomorrow Lucinda.
I too looked at the youtube video's briefly and they are very graphic as Ray says.
The good thing is that you will not see any of this. Like many here I healed very well and most people would hardly notice the slight scaring on the neck.
Maybe you might like to keep your own photographic history of your recovery process? I have lot's of photo's starting 2 weeks after surgery of both wrist,thigh,neck but mostly ones I took of my own mouth.
Again all the very best and when able let us know how you are going.
