I can just imagine what it takes to be a head/neck surgeon.
For one, the video shows arteries red and veins blue - in reality they aren’t that well highlighted.
Another thing, the video has proper dissection, with the structures fully visible and perfectly laid in 3D. The surgeons often operate through small incisions, just by “feeling” the structures, or with a small camera.
And finally… There are lots of anatomical variations. What’s in the video, doesn’t necessarily perfectly match what the surgeons find “inside”…
So I really can’t blame those who don’t want to do the surgery in these areas unless it’s a life or death case, as chances to make a serious mistake are high.
