Trepanning

Trepanning is a very old practice that involves making a hole in the skull of a person. It sounds scary, but it was actually done to help people who had problems with their brain or their head.

When a person has something wrong with their brain, it can cause pressure inside their head. This can make them feel very sick and can even make them die. Trepanning was a way to help relieve this pressure and make the person feel better.

To do trepanning, a special tool called a trephine was used. This tool was like a round saw that could cut a small hole in the skull. It was important to be very careful when doing this because you didn't want to hurt the brain inside.

Once the hole was made, the pressure inside the person's head was relieved and they would usually start feeling better. Sometimes, people would put things inside the hole to help it heal, like herbs or even pieces of gold.

People have been doing trepanning for a very long time, even back in ancient times. Today, doctors have other ways to help people with brain problems, so trepanning is not used very often anymore. But it's important to remember that it was a helpful way to relieve pressure and help people feel better.
