Me too!!
In fact, I have two indentations. The first dent is on the top of my forehead, next to where the shunt goes into my skull - maybe they should have smoothed it over with more bone cement? The other is behind my left ear and at the base of my skull. There seems to be an
entire section of bone and cartilage missing. There's a titanium mesh in there someplace but I've never been able to feel it. My most visable and dramatic sign is the shunt on top of my forehead. It's a collapsible, pump-like device that protrudes from under the skin like a mountain ridge. There is a cathetar that goes into the skull on one end - where the indentation is - and the other snakes across the side of my head, down the right side of my neck, across my chest - just beneath the skin - and disappears down in my abdominal region. There is an accompanying scar on the right side of the abdomen along with the incision made for adipose tissue to plug the dura up on the opposite side. Those abdominal incisions hurt the worst when healing up!
I have a friend who is from England that lives up in the wild and wooly hinterlands of Western Maine. As a teenager living in England, he was attacked in a fight and had a hammer imbedded in his skull. The doctors that worked on him couldn't believe he survived the attack at all, never mind walking away from it without any problems. He's now in his early forties and in good health. You should see the indentation in his head!!
