When a baby’s skull joins together too early, parents may notice changes in head shape, forehead position, or facial symmetry. This condition is called craniosynostosis. It happens when one or more skull sutures, the flexible seams between the bones of the skull, close before the brain has finished growing.
For many families, the first sign is an abnormally shaped skull noticed at birth or during the first months of life. Some changes are mild. Others are easier to see, such as a long, narrow head, a flattened forehead, uneven eyes, or flattening at the back of the head.
For parents looking for types of craniosynostosis explained in clear, reassuring language, understanding the main forms can help you know what to look for, what questions to ask, and when to seek specialized care. If you have concerns about your child's head shape or a possible diagnosis, learning about available craniosynostosis treatment in New Jersey can help you take the next step with confidence.
There are four main types often discussed by the suture involved: sagittal, coronal, metopic, and lambdoid. Some children have single-suture craniosynostosis, while others have more cranial sutures involved, which may point to a more complex condition.
At New Jersey Pediatric Neuroscience Institute, families receive child-centered neurology and neurosurgery care with direct communication, individualized treatment planning, and support before, during, and after care. If you are worried about your child’s head shape, a pediatric neurosurgical evaluation can help determine whether craniosynostosis is present and what steps may be right for your child.
A baby’s skull is made of several bones separated by flexible sutures. These sutures allow the skull to expand as the brain grows. In craniosynostosis, one or more sutures close too soon. Because growth is restricted in one direction, the skull may grow differently in another direction. This creates the head shape pattern linked to the fused suture.
Craniosynostosis may be visible soon after birth, or it may become clearer as the child grows. Parents may notice that the head does not look round, that one side appears different from the other, or that a ridge can be felt along part of the skull. In some children, the forehead, eyes, ears, or back of the head may look uneven.
Early evaluation matters because the skull is growing quickly during infancy. Timely diagnosis can help the care team monitor brain development, assess pressure inside the head, and decide whether surgery or observation is appropriate. Understanding the potential risks of untreated craniosynostosis can help parents appreciate why early assessment and follow-up are so important. Not every child has the same needs. Age, suture involvement, head shape, symptoms, and overall health all influence the care plan.
Parents should contact a specialist if they notice:
A head shape that appears long, narrow, flat, triangular, or uneven
A raised ridge along the skull
A forehead that looks flattened, prominent, or asymmetric
Eyes or ears that appear uneven
Slow or unusual head growth
Concerns about feeding, irritability, development, or vision
Many babies have flat spots from sleeping position, and not every head shape concern is craniosynostosis. A specialist can help tell the difference and guide families with confidence.
The main types are named for the suture that closes too early. Each pattern affects head shape in a different way. Some types are more common than others, and some are more likely to be linked with a syndrome or additional medical needs.
| Type | Suture involved | Common head shape features | What parents may notice |
|---|---|---|---|
| Sagittal craniosynostosis | Sagittal suture on top of the head | Long, narrow head, often called scaphocephaly | Prominent forehead or back of head, ridge along the top of the skull |
| Coronal synostosis | One or both coronal sutures near the front of the skull | Flattened forehead on one side, facial asymmetry, or short, wide head if both sides are involved | Uneven brow or eye position, forehead asymmetry |
| Metopic craniosynostosis | Metopic suture from the top of the head toward the nose | Triangular forehead shape, sometimes called trigonocephaly | Narrow forehead, eyes that seem close together, ridge in the middle of the forehead |
| Lambdoid craniosynostosis | Lambdoid suture at the back of the head | Flattening or slanting at the back of the skull | Ear position changes, back-of-head asymmetry |
| Multisuture synostosis | Two or more sutures | More complex skull shape changes | May involve increased pressure risk, syndrome evaluation, and coordinated care |
Some children have nonsyndromic craniosynostosis, meaning it occurs without a related genetic syndrome. This is often seen with a single fused suture. Other children have syndromic craniosynostosis, which may be related to genetic syndromes and may involve the face, hands, feet, airway, eyes, or other parts of the body.
Secondary craniosynostosis is less common and may occur because of another medical condition that affects skull or brain growth. Because the causes of craniosynostosis vary, an accurate diagnosis is important before making treatment decisions.
Sagittal craniosynostosis is the most common type of craniosynostosis. It occurs when the sagittal suture, which runs from front to back along the top of the head, fuses early. This limits side-to-side growth and causes the head to grow longer from front to back. The medical term for this head shape is scaphocephaly.
Parents may notice that their child’s head looks long and narrow. The forehead may look prominent, and the back of the head may also appear more noticeable. A firm ridge may be felt along the top of the head where the suture has fused.
The goal of evaluation is to understand the degree of fusion, the child’s age, skull growth, and any signs that the condition may affect health or development. Imaging may be used when needed, along with a careful physical exam and head measurements.
Treatment depends on the child. Some infants may be candidates for different surgical approaches depending on their age, diagnosis, head shape, and specialist evaluation. Surgery may help release the fused bones, improve skull growth, and create a more balanced head shape. Follow-up helps the team monitor healing, development, and long-term progress.
NJPNI’s approach supports the whole family. Parents receive clear explanations, time to ask questions, and guidance on what to expect if surgery is recommended. The goal is not only to treat the fused suture, but to help each child move forward with attentive, individualized care.
Coronal synostosis affects one or both coronal sutures, located near the front of the skull from ear to ear. When one side closes early, the forehead on that side may look flattened. The opposite side may appear fuller. The brow or eye socket can also look uneven, which may make facial asymmetry easier to notice.
When both coronal sutures close early, the head may look shorter from front to back and wider from side to side. Bilateral coronal involvement is more likely to raise concern for syndromic craniosynostosis, especially if other features are present.
Metopic craniosynostosis affects the suture that runs from the top of the head down the middle of the forehead toward the nose. Babies with metopic fusion may have a triangular forehead shape. Some have a visible ridge in the center of the forehead, narrowing at the temples, or eyes that appear close together.
A ridge alone does not always mean surgery is needed. Some metopic ridging can be mild. A specialist can determine whether the forehead shape reflects true craniosynostosis and whether the child needs monitoring or treatment.
For both coronal and metopic forms, care planning may include:
Physical exam, head measurements, and review of growth history
Imaging when needed to confirm which suture has fused
Evaluation for vision, development, or signs of pressure
Discussion of surgical timing and expected recovery if treatment is recommended
Ongoing follow-up as the child grows
Families often feel anxious when changes involve the forehead, eyes, or face. Clear guidance helps reduce uncertainty. NJPNI works with parents to explain the findings, review treatment options, and create a plan that supports both health and appearance.
Lambdoid craniosynostosis is rare. It occurs when one or both lambdoid sutures at the back of the skull close too early. Because it affects the back of the head, it may be confused with positional plagiocephaly, which is flattening caused by repeated pressure on one area of the skull.
The difference matters. Positional flattening does not involve fused skull bones. Lambdoid craniosynostosis does. A specialist can evaluate head shape, ear position, skull base tilt, and other signs to help separate these conditions.
With lambdoid craniosynostosis, parents may notice flattening or slanting at the back of the head. The ear on the affected side may sit differently. The skull base may look tilted. In positional plagiocephaly, the pattern is often different, and treatment may include repositioning, physical therapy, or helmet therapy rather than craniosynostosis surgery.
Because lambdoid fusion is uncommon, expert evaluation is especially helpful. If surgery is needed, the goal is to release the fused area, improve symmetry, and support normal skull growth. If surgery is not needed, families still benefit from a clear diagnosis and a plan for monitoring.
Multisuture synostosis means that two or more skull sutures close too early. These cases can create more complex skull shape changes and may carry a higher risk of increased pressure inside the head. Some children with multisuture involvement have syndromic craniosynostosis, while others do not.
Syndromic forms may be associated with conditions such as Apert, Crouzon, Pfeiffer, or other craniofacial syndromes. These children may need care from several specialists over time. Depending on the syndrome, treatment may involve the skull, face, airway, eyes, hearing, dental development, hands, feet, or developmental support.
Multisuture and syndromic cases require careful planning. The care team may consider whether surgery should happen in stages, how to monitor brain development, and which specialists should be involved. Genetic testing or counseling may be recommended for some families.
A strong care plan is built around the child and family. It should explain what is known now, what needs to be watched over time, and what decisions may come next. At NJPNI, families can expect a collaborative approach that values parent insight, clear communication, and coordinated pediatric neurosurgical care.
If your child has been diagnosed with a syndrome, has more than one fused suture, or has symptoms that raise concern for pressure or developmental impairment, prompt evaluation is important. The right team can help protect your child’s health while supporting your family through each step.
Parents are often the first to notice that something looks different. Trust that instinct. A head shape concern does not always mean a child needs surgery, but it does deserve a careful evaluation when craniosynostosis is possible.
