From time to time, articles circulate online claiming that a specific mark, crease, or feature on the ear can reveal important information about a person’s health. One of the most commonly discussed examples is a diagonal crease on the earlobe, sometimes called Frank’s sign.
What Is Frank’s Sign?
Frank’s sign is a diagonal line or crease that runs across the earlobe, usually at an angle from the ear canal toward the lower edge of the lobe.
It was first described in 1973 by physician Dr. Sanders T. Frank.
Why Has It Attracted Attention?
Some studies have suggested a possible association between earlobe creases and an increased risk of cardiovascular disease.
Researchers have proposed several theories, including:
- Changes in blood vessels
- Aging-related tissue changes
- Reduced circulation in small blood vessels
However, the exact relationship remains unclear.
Does an Earlobe Crease Mean Heart Disease?
No.
Having an earlobe crease does not mean that a person has heart disease.
Many people with the crease are perfectly healthy, while many people with heart disease do not have the crease.
Medical experts generally view it as, at most, a possible marker that may warrant attention when considered alongside other risk factors.

More Important Risk Factors
Doctors place far greater emphasis on factors such as:
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- Obesity
- Lack of physical activity
- Family history of heart disease
These are much stronger predictors of cardiovascular risk.
Other Marks on the Ear
Various ear features may be completely normal and harmless, including:
- Small dimples
- Minor skin folds
- Natural variations in shape
- Tiny bumps or indentations
Most ear characteristics are simply part of normal human variation.
When Should You See a Doctor?
Consult a healthcare professional if you notice:
- Pain
- Sudden changes in appearance
- Persistent swelling
- Bleeding
- Unusual growths
- Signs of infection
These symptoms deserve medical evaluation regardless of any crease or mark.
