The drilling part caught me off guard. It suddenly got my heart beating fast. Hahaha<br><br>Btw, what happens to the skull afterwards? Will there be a hole there forever or are they going to do something to close it?,(reply>), Smaller holes may simply be left to heal with the scalp closed over it - larger holes, and those that are in cosmetically important areas such as the forehead, can be covered with a titanium plate which is fixed to the surrounding skull!
