PLAGIOCEPHALY
What Is Plagiocephaly?
Plagiocephaly — commonly called flat head syndrome — is a condition where one area of a baby's skull becomes flattened, creating an asymmetrical head shape. It's one of the most common concerns pediatricians see in the first year of life.
Positional plagiocephaly develops from sustained pressure on one area of the skull, typically from consistently lying or turning in the same direction. Because a baby's skull bones are soft and malleable, repeated pressure in one spot can reshape the cranium over time.
Causes of Flat Head in Babies
Plagiocephaly is almost always secondary to something else — it's the effect, not the root cause. The most common underlying factors are torticollis or cervical tension limiting head rotation (baby can't comfortably turn both ways, so they default to one side), birth positioning or intrauterine constraint that creates a preference, prolonged time in car seats, swings, or flat surfaces, and cervical misalignment creating muscle guarding that restricts movement.
Understanding the underlying driver is critical. If the cause isn't addressed, repositioning strategies and even helmets may not produce lasting results.
The Torticollis-Plagiocephaly Connection
Torticollis and plagiocephaly frequently occur together. When a baby's neck is tight or misaligned, they favor turning their head one direction. That sustained pressure flattens one side of the skull. Addressing the torticollis often resolves the plagiocephaly — because once baby can move their head freely in both directions, the pressure distributes evenly and the skull reshapes naturally.
How Chiropractic Helps
Dr. Jennifer's approach to plagiocephaly focuses on the underlying tension pattern — not just the flat spot itself. Gentle cervical adjustments address misalignment that's restricting head rotation. Cranial techniques support symmetrical cranial motion and growth. And as the nervous system component is resolved, baby begins moving their head freely, redistributing pressure and allowing natural reshaping.
This is most effective when caught early, while the skull is still highly malleable and responsive to improved movement patterns.
When to Seek Care
If you notice asymmetry in your baby's head shape, a persistent preference to turn one direction, or a developing flat spot — seek assessment sooner rather than later. The earlier the underlying cause is addressed, the more responsive the cranium is to natural correction.
Dr. Jennifer can also advise on positioning strategies, tummy time recommendations, and whether a referral for helmet evaluation is appropriate alongside chiropractic care.
Frequently Asked Questions
-
Yes. By addressing the cervical tension and misalignment driving the positional preference, chiropractic care allows baby to move their head freely — which redistributes pressure and supports natural cranial reshaping.
-
Frequently, yes. Torticollis restricts head rotation, causing baby to favor one side. That sustained pressure creates the flat spot. Addressing the torticollis often resolves the plagiocephaly.
-
As early as possible. The skull is most malleable in the first 4–6 months. Early intervention produces the best results.
-
Not always. Many cases of plagiocephaly improve significantly with chiropractic care and repositioning strategies alone. Dr. Jennifer will assess your baby's severity and recommend whether a helmet evaluation is warranted alongside care.
