Mystery solved! THIS is what that tiny hole above the ear is all about
If you were big into piercings back in the day, chances are you have a couple of tiny holes in your ears which you no longer adorn with jewellery.
And while most of us assume every small hole in a person's ear is the result of a past piercing, this isn't actually the case – something you'll be all too familiar with if you have a rare condition called preauricular sinus.
Preauricular sinus presents as a tiny hole where the ear cartilage joins the face, and is a harmless condition which affects, on average, one in 100 people.
First documented by scientist Van Heusinger back in 1864, preauricular sinus appears during early foetal development and is hereditary.
