Have you ever noticed a small, seemingly random hole near the top of your ear, usually just above the ear canal or near the crease where the ear meets the face? Many people spot it and wonder: “Is this normal? Is it dangerous?” Surprisingly, this tiny feature has a fascinating explanation—and it might reveal something about your genetics, development, and even health.
What Is That Tiny Hole Called?
That little hole is medically known as a preauricular sinus or preauricular pit. It’s a small opening that can be present at birth and is relatively rare in some populations, though more common in others. Estimates suggest about 1–10% of people worldwide may have one, often unnoticed until an infection occurs or it’s pointed out.
