Look no further than your own ears. In their essence, they serve as the organ that allows us to connect with the world through sounds. And maybe you didn’t know this, but there are people out there in the world that have tiny holes near where their ear connects with the rest of their head.
No, it is not an unfortunate mishap while piercing their ears. Those people were born with that little hole, and it is quite interesting when you find out why.
Fun fact: if you live in the United Kingdom or the United States, there is less than one percent chance that you have one.
The first reported occurrence of the preauricular sinus was documented back in 1864 by a scientist known as Van Heusinger. The study was published in the US National Library of Medicine. However, we can safely assume that it was around for hundreds of years before that.
However, preauricular sinuses are completely harmless. At times they can get infected but can be adequately handled with surgery.
