Posterior plagiocephaly is a condition in which the back part of an infant’s skull appears flattened or asymmetrical. Unlike general head shape variations, posterior plagiocephaly specifically refers to flattening at the occipital area, which can give the head a parallelogram-like shape when viewed from above. This flattening often develops in the first few months of life, as infants spend a lot of time lying on their backs during sleep or rest.
Posterior plagiocephaly arises when external forces—such as persistent supine positioning—apply uneven pressure on an infant’s still-malleable skull. In true craniosynostosis, a fused lambdoid suture prevents symmetric skull growth, leading to compensatory expansion elsewhere and a parallelogram-shaped head. Signs include a flat zone at the back of the head, ipsilateral ear displacement, and possible forehead bossing on the opposite side. Diagnosis often relies on clinical examination and imaging (ultrasound or CT) to distinguish deformational from synostotic forms.
The flattening in posterior plagiocephaly results from constant external pressure on a soft, malleable skull. While many cases are positional and improve with simple interventions, some forms arise because of early fusion of skull sutures (craniosynostosis), requiring more specialized care. Early recognition and targeted management can help restore a more typical head shape and support optimal brain development.
Types of Posterior Plagiocephaly
Deformational (Positional) Plagiocephaly
This is the most common form of posterior plagiocephaly. It occurs when repeated pressure flattens one side of an infant’s skull. Factors include always turning the head to the same side or spending too much time supine without sufficient supervised “tummy time.”Synostotic (Lambdoid Craniosynostosis)
In this rarer type, one of the lambdoid sutures at the back of the skull fuses prematurely. This early fusion prevents normal growth in that area, causing compensatory bulging elsewhere. Synostotic plagiocephaly often requires surgical correction.Mixed or Complex Plagiocephaly
Some infants exhibit features of both positional flattening and suture fusion. Careful evaluation—including imaging—is crucial to determine the exact mix and to plan appropriate treatment, which may involve both conservative and surgical approaches.
Causes of Posterior Plagiocephaly
Supine Sleep Position
Infants sleeping on their backs without supervised tummy time are at higher risk of pressure-induced flattening at the occiput.Limited Tummy Time
Lack of prone positioning during awake periods reduces opportunities for the head to relieve pressure on the back.Preferential Head Turning
Babies who habitually turn their head to one side—often due to comfort or lighting—can develop asymmetrical flattening.Torticollis
Tightness or imbalance in the neck muscles (often the sternocleidomastoid) makes an infant favor one side, increasing unilateral pressure.Multiple Births
Twins or triplets often have less room in the womb, which may predispose them to positional head flattening even before birth.Premature Birth
Preterm infants have softer skulls and may spend extended time in neonatal intensive care, often in incubators that limit head movement.Intrauterine Constraint
Restricted space or positioning in the womb—due to low amniotic fluid, multiparity, or uterine anomalies—can cause early flattening.Positional Devices
Extended use of carriers, bouncers, or car seats can concentrate pressure on the same part of the skull.Congenital Muscular Torticollis
A birth trauma or in-utero positioning can injure neck muscles, causing an infant to hold the head crookedly.Low Birth Weight
Smaller infants often require medical positioning that can unintentionally apply persistent pressure.Prolonged Hospital Stays
Hospital equipment in neonatal care units may limit head movement, increasing the risk of deformational changes.Genetic Predisposition
Some families may have a naturally flatter skull shape tendency that becomes exaggerated under pressure.Neuromuscular Conditions
Conditions that impair normal motor control can lead to less spontaneous head movement and more flattening.Hypotonia
Low muscle tone in infants makes it harder for them to reposition their heads, concentrating pressure in one area.Environmental Constraints
Tight swaddling or clothing that restricts head movement can contribute to flattening over time.Recovery from Illness or Surgery
Extended bed rest with the head in one position can produce localized pressure effects.Maternal Uterine Anomalies
Uterine fibroids, septate uteri, or a bicornuate uterus can create abnormal fetal positioning.Oligohydramnios
Low amniotic fluid volume limits cushioning in utero, increasing direct pressure on the fetal skull.Large Birth Weight
Larger babies may already have head molding before birth and then continue to be positioned likewise.Lack of Parental Awareness
Without education on repositioning and supervised tummy time, parents may inadvertently leave infants in the same head position too long.
Symptoms of Posterior Plagiocephaly
Flattened Occiput
A visibly flat area on the back of the head that may be unilateral or bilateral.Parallelogram Head Shape
When seen from above, the head may look skewed, like a parallelogram rather than an oval.Ear Misalignment
One ear may appear pushed forward compared to the other.Forehead Bulging
Compensatory growth can cause prominence in the frontal region opposite the flattening.Eyebrow Ridge Prominence
One brow may look more pronounced due to cranial asymmetry.Facial Asymmetry
Subtle shifts in jaw or cheek position may accompany the cranial changes.Neck Discomfort
Torticollis or positional preference can cause neck muscle tightness.Limited Neck Mobility
Difficulty turning the head side-to-side due to muscular or skeletal constraints.Positional Preference
The baby may almost always look one way, refusing to turn the head fully.Developmental Delays
In rare, severe cases, skull deformity can relate to delayed motor milestones.Feeding Difficulties
Asymmetry can make latch or bottle feeding slightly more challenging on one side.Irritability
Discomfort or tension in neck muscles may make infants fussier when repositioned.Sleep Disturbances
Babies might resist supine sleep positioning if it aggravates muscle tightness.Vestibular Issues
In severe asymmetry, balance and spatial orientation might be subtly affected.Recurrent Ear Infections
Ear misalignment can impair drainage, slightly raising infection risk.Jaw Joint Strain
TMJ discomfort may arise in later infancy or toddlerhood due to skull alignment issues.Headache-like Symptoms
Older infants or toddlers may show signs of discomfort in the head when lying prone.Visual Tracking Asymmetry
One-sided head posture can affect smooth pursuit eye movements.Preference for One Hand
Early handedness might be seen if infants avoid turning their head to the other side.Speech Delay
In very rare, extreme cranial asymmetry, later articulation patterns can be mildly affected.

Frequently Asked Questions
What Causes Posterior Plagiocephaly?
A combination of positional forces and, in some cases, early suture fusion leads to asymmetrical skull flattening.How Common Is It?
Positional plagiocephaly affects up to 20% of infants, while true lambdoid synostosis is rare (<1 per 10,000).Can It Correct on Its Own?
Mild positional flattening often improves with repositioning; synostosis requires surgery.Is Helmet Therapy Necessary?
Indicated for moderate to severe cases unresponsive to conservative measures after 4–6 months.Does It Affect Brain Development?
Positional forms do not directly impair cognition; untreated synostosis can raise intracranial pressure.When Should Treatment Start?
Ideally between 4–6 months of age, when skull bones are most malleable.Are There Risks to Helmets?
Minor skin irritation or discomfort; close follow-up minimizes complications.How Long Is Therapy Needed?
Varies from weeks (mild) to 12 months (severe helmeting plus therapy).Will My Child Need Surgery?
Only if craniosynostosis is confirmed; most positional cases avoid surgery.Can Plagiocephaly Return?
Rare if prevention strategies are adhered to during first year.Does It Impact Facial Symmetry?
Severe cases can shift ear and jaw alignment if untreated.Is Physiotherapy Effective?
Yes—when started early, it can reduce asymmetry by 50–70%.Should I Worry About Torticollis?
Yes—untreated neck muscle tightness perpetuates head flattening.Can Massage Alone Help?
It aids muscle relaxation but should be paired with active repositioning.Are Supplements Helpful?
They support bone health but are adjuncts to mechanical therapies.
