Understanding the Glabella: What is the Forehead Indentation?

The frontal bone is the bone that forms the forehead. It is a flat bone with a slight indentation in the middle. This indentation is called the glabella. The glabella is a normal anatomical feature and is not a cause for concern. However, if you have a deep indentation in your forehead bone that is not there or has never been present before, you should see a doctor to rule out any underlying medical conditions.
