Facial Landmarks Our AI Reads—And What They Mean

AI Facial Screening, Diagnosis Pathways
April 30, 2025

A single photo could be the first clue to diagnosing a dangerous sleep disorder. With advancements in deep-learning technology, your face can now reveal signs of obstructive sleep apnea (OSA)—without wires, overnight labs, or bulky devices.

Our AI-powered scan identifies subtle structural patterns linked to nighttime breathing disruptions. By analyzing precise facial landmarks, it helps predict risk levels based on peer-reviewed research. Let’s break down the key measurements, what they mean, and how this fast, non-invasive tool fits into the sleep screening process.

How a Photo Becomes Predictive

When you take our 60-second scan, the AI analyzes over 100 anatomical markers across your face. This includes cheek volume, jaw width, neck circumference, and chin structure. Each of these plays a critical role in how easily your airway may collapse during sleep—a hallmark of OSA.

According to a 2023 study published in the journal Nature and Science of Sleep, facial morphology—including mandibular angle and face width—is significantly different in individuals with moderate to severe OSA.

Key Facial Landmarks We Analyze

Mandibular Angle

One of the most important markers is the angle of your lower jaw. A steeper mandibular angle can indicate a recessed jaw, which may reduce airway space. Several clinical studies, including this one in Frontiers in Physiology, found a correlation between retrognathia and higher apnea risk.

Neck and Chin Ratio

Our AI evaluates the vertical length from chin to neck base and compares it to overall face height. A shorter vertical neck-chin ratio is commonly associated with increased soft tissue pressure on the airway.

This insight aligns with findings from the American Academy of Sleep Medicine that describe thick neck circumference as a known predictor of OSA.

Cheek Volume and Midface Width

A broader midface or increased fat deposition around the cheeks may reflect airway crowding. According to Sleep Review Magazine, 3D facial scanning reveals significant associations between facial width and sleep apnea presence—especially in men.

Nasolabial Depth and Nose Bridge Width

The scan also looks at nasal bridge symmetry and nasolabial angles. While these aren’t direct causes of apnea, they can affect breathing ease and airflow resistance. A flatter nasal bridge is often associated with narrower nasal passages, which can contribute to mouth breathing—a known risk factor for OSA.

Why AI Facial Screening Is Gaining Momentum

Sleep apnea is notoriously underdiagnosed, especially in women and people with non-obese body types. Traditional screening tools like BMI and neck circumference don’t work equally across populations. AI facial analysis is a promising equalizer, offering consistent, bias-minimized risk assessment across age, gender, and ethnicity.

A paper in Sensors describes how convolutional neural networks (CNNs) are now achieving high accuracy by mapping facial soft tissue and bone relationships to AHI scores.

What the AI Scan Does Not Do

It’s important to understand that our scan does not diagnose sleep apnea. Instead, it flags anatomical features correlated with increased risk, helping clinicians determine whether further testing is appropriate. If flagged, you’ll be guided to take a home sleep test or speak to a licensed provider.

Next Steps After a Positive Scan

If your facial scan shows indicators of risk, here’s what comes next:

Step 1: A provider reviews your scan and medical history
Step 2: You may be prescribed a home sleep apnea test (HSAT)
Step 3: Results are returned in 48 hours
Step 4: Based on findings, the provider discusses your treatment options, such as CPAP therapy or oral appliances

This entire process takes place remotely, without in-lab visits.

Limitations to Be Aware Of

No AI tool is perfect. Facial swelling, poor lighting, facial hair, or camera distortion may affect scan accuracy. Also, structural markers alone can’t detect central sleep apnea or other neurologically driven breathing disorders.

That’s why we always pair AI scan results with licensed clinical review and, when necessary, further testing.

Facial Landmark Screening vs. Other Methods

Screening Type	Time	Invasiveness	Predictive Scope
AI Facial Scan	60 seconds	Non-invasive	Structural OSA risk
STOP-Bang Questionnaire	5 minutes	Non-invasive	Risk scoring based on history
In-Lab Polysomnography	Overnight	Invasive	Full diagnostic

The AI scan serves as a first filter—making apnea screening more accessible while reducing the burden on labs and patients.

The Future of Preventative Sleep Screening

With tools like this, we’re moving sleep health upstream. You don’t have to wait until severe symptoms appear. Instead, a quick scan can give you early insights and peace of mind.

The best part? You can do it from home, in your pajamas, without needing wires, gels, or overnight stays.
