You’re brushing your teeth, looking in the mirror, and you see it. A diagonal line cutting right across your earlobe. It looks like a deep wrinkle, maybe just a sign of getting older, or perhaps you slept on it wrong. But then you go online. You start scrolling through crease in earlobe images and suddenly the search results are screaming about heart disease, blocked arteries, and "Frank’s Sign." It’s enough to make anyone’s heart skip a beat—literally.
Is it a death sentence? Honestly, no. But it isn't something you should just ignore either.
This weird physical trait has been debated in medical journals for decades. It’s one of those strange "surface markers" where the outside of your body might be whispering secrets about what’s happening on the inside. We’re talking about a specific diagonal fold that runs from the tragus (that little nub of cartilage in front of the ear canal) down to the rear edge of the lobe.
The Backstory: Who is Frank and Why is He on Your Ear?
In 1973, a doctor named Sanders T. Frank noticed something. He published a letter in the New England Journal of Medicine describing a link between this diagonal crease and coronary artery disease in his patients. Since then, the medical community hasn't stopped arguing about it.
Some doctors swear by it. Others think it’s just a byproduct of age and loss of skin elasticity.
The reality is usually somewhere in the middle. When you look at crease in earlobe images, you’ll notice varying depths. A faint line is one thing; a deep, permanent "canyon" in the lobe is what usually catches a cardiologist's eye. The theory—and it's still just a theory, though backed by some compelling data—is that the earlobes and the heart share similar blood supply pathways. If the tiny blood vessels in your ears are collapsing or losing collagen, the same might be happening in the vessels surrounding your heart.
What the Science Actually Says (And What It Doesn't)
Let's look at the numbers. A study published in the American Journal of Medicine found that a diagonal earlobe crease was associated with an increased risk of heart disease, even after the researchers accounted for other things like age and smoking habits.
Wait.
Don't panic yet. Correlation is not always causation. Just because people with the crease often have heart issues doesn't mean the crease causes the heart issue. It’s a marker. Like a check engine light. You wouldn't say the light caused the engine to smoke, right?

There was a massive study involving over 200 patients who underwent coronary angiography. The researchers found that Frank’s sign had a "positive predictive value" of about 71%. That sounds high. But it also means that nearly 30% of people with the line had perfectly clear arteries. You could be in that 30%.
Also, we have to talk about ethnicity. Interestingly, some studies suggest that the link between ear creases and heart health is much stronger in certain populations (like Caucasian and Japanese groups) than in others. If you’re looking at crease in earlobe images to self-diagnose, you have to realize that genetics play a massive role in how our skin folds.
Why Does the Crease Even Form?
Scientists have a few guesses.
- Loss of Elastin: Your earlobes are full of capillaries. If your vascular health is poor, the blood flow to the lobe decreases, causing the skin to fold.
- Genetic Overlap: The same genes that dictate how your blood vessels handle cholesterol might also dictate how your earlobe collagen holds up over time.
- DNA Damage: Some researchers believe that "shortened telomeres" (markers of cellular aging) show up in the earlobe before they show up in more critical organs.
Sorting Through Crease in Earlobe Images: What to Look For
If you’re comparing your own ear to photos online, detail matters.
A simple horizontal wrinkle from a pillow? Not Frank's Sign.
A vertical line? Probably just skin aging.
The "classic" Frank’s Sign is a 45-degree diagonal. It usually starts at the bottom of the ear canal opening and tracks backward. Doctors sometimes grade them. Grade 1 is a tiny bit of wrinkling. Grade 2a is a superficial crease. Grade 2b is a deeper crease. Grade 3 is a full-on deep cleft that goes all the way across.
The deeper and more bilateral (on both ears) the crease is, the more likely doctors are to take it seriously. If you only have it on one side, it might just be the side you sleep on. Side-sleeping for 40 years can do a number on your skin.
When Should You Actually Worry?
Look, if you are 25 and have a deep diagonal crease, that’s unusual. It’s worth a conversation with a doctor because you shouldn't be losing that much collagen that early.

However, if you are 75, skin loses its bounce. It happens to everyone. In older populations, the earlobe crease is much less predictive of heart disease because, well, everyone has wrinkles at 75.
You should pay attention if the crease is accompanied by:
- Chest tightness when you walk up stairs.
- Shortness of breath that feels "new."
- High blood pressure or high cholesterol.
- A family history of early heart attacks.
Essentially, Frank's Sign is a piece of a puzzle. It’s never the whole picture.
The Controversy: Critics and Skeptics
Not every doctor is a believer. Some call it "the wrinkle of the aged." They argue that people who have heart disease are generally older, and people who are older generally have wrinkles. Therefore, saying the wrinkle predicts the disease is just stating the obvious.
One famous study in the British Heart Journal argued that the earlobe crease was simply a sign of how long a person had been alive, rather than how sick their heart was. They pointed out that many people with severe coronary blockages have perfectly smooth ears.
This is why you can’t just look at crease in earlobe images and decide you’re in trouble. It’s a "soft sign." It’s a reason to get a blood test, not a reason to write your will.
What to Do Next: Actionable Steps
If you’ve checked the mirror and you definitely have the crease, don't spiral. Here is the logical, expert-backed way to handle it.
1. Check Your "Big Numbers"
Go to a clinic and get your "Lipid Panel" done. This checks your LDL (bad cholesterol), HDL (good cholesterol), and triglycerides. If your ears have the crease but your bloodwork is pristine, your heart is likely in great shape.

2. Monitor Your Blood Pressure
The earlobe crease is often linked to hypertension. Invest $30 in a home blood pressure cuff. Check it a few times a week. If you’re consistently over 130/80, that’s a much bigger deal than the line on your ear.
3. Examine Your Lifestyle Honestly
Are you smoking? Do you eat processed sugar daily? Do you move your body? If you have Frank’s sign and you have a sedentary lifestyle, consider the crease a "gift" from your body—a visual warning to change habits before they become medical emergencies.
4. Talk to a Doctor, But Be Specific
Don't just walk in and say "I have a weird ear." Say: "I noticed a diagonal earlobe crease, also known as Frank's Sign. Given the literature linking this to coronary artery disease, I’d like to do a cardiovascular screening to rule out any underlying issues." This shows you're informed and moves the conversation toward diagnostic testing like an EKG or a calcium score test.
5. Don't Forget the Basics
Sleep on your back for a week and see if the crease softens. If it does, it was probably just mechanical pressure from your pillow.
The bottom line is that our bodies are communicative. Sometimes they communicate through pain, sometimes through fatigue, and sometimes through a strange little line on an earlobe. It’s a fascinating bit of human anatomy that serves as a reminder: the cardiovascular system isn't isolated. It's connected to everything, right down to your ears.
Treat Frank's Sign as a nudge to prioritize your health. Whether the link is 100% proven or not, taking better care of your heart is never a waste of time.
Next Steps for Your Health Tracking
- Schedule a Fasting Glucose Test: Blood sugar issues can also damage small vessels, contributing to skin creases.
- Review Your Family Tree: Find out if any relatives had heart issues before age 55. This makes the earlobe marker more significant.
- Focus on Collagen Support: Regardless of heart health, staying hydrated and using sunscreen can prevent the deepening of skin folds like Frank’s Sign.
