Lamboid craniocerebral cranium occurs when the laryngeal suture that joins the baby’s skull fuses prematurely. The lambdoid suture runs through the back of the head. When it merges, the back of the head appears to be flattened. It is one of the rarest types of cranial diseases – a congenital defect that affects the baby’s skull joints.

The sutures usually stay open until the baby’s second birthday. This allows the brain room to grow and develop. In the case of craniocerebral disease, one or more of the sutures fuse prematurely. This results in a horse growing on a skull or head. It can also increase the pressure on the brain.

Treatment for lambdoid craniosynostosis includes surgery to correct the scalp and allow room for brain growth.

Types of craniosynostosis:

There are different types of craniocerebral diseases other than lambidoid craniocerebral disease, including:

  • Sagittal craniocerebral disease It is the most common type of craniocerebral disease. It affects the sagittal suture at the front and back of the head. This results in a long, narrow head.
  • Coronary artery disease Affects one or both of the crown sutures that extend from the ear to the top of the head. This type of cranial inflammation causes a flattened, bulging appearance on the affected side of the forehead.
  • Metopic craniocerebral disease Affects the metopic suture, which runs from the bridge of the nose to the top of the head. This type of cranial inflammation causes a triangular shape of the forehead, widening the area behind the head.

Lambdoid Craniosynostosis Symptoms:

The most noticeable sign of lambidoid craniocerebral spine is flattening of the back of the head. You may also notice that your baby’s ear և forehead on the affected side seems to be retracted. This gives the head the appearance of a trapezoid. The ear on the injured side may also look lower than the ear on the unaffected side.

Other common symptoms of lambidoid craniocerebral cortex include:

  • A solid ridge along the lamb suture at the back of the head
  • Slowing down the growth of the head while the body continues to grow

Rare symptoms may include:

  • Drowsiness or fatigue
  • Irritation և crying
  • More obvious veins in the head
  • Poor nutrition
  • Projectile vomiting
  • Head magnification (contour)
  • Acceleration delay

Is it definitely a craniocerebral disease if your baby’s head looks out of place?

If you notice that the back of your baby’s head seems to be misaligned, it may not be a lambid cranium. Babies who spend most of the day on their backs may have flattened buttocks, as their flexible skull bones can be easily fused. This condition is known as positional plagiocephaly. This benign condition does not affect brain growth and does not require surgery.


Lambdoid craniosynostosis is often considered an accidental congenital defect and has no known cause. It can be caused by a combination of genetic or environmental factors.

While we do not yet understand the exact causes of lambidoid craniocerebral disease, there are some risk factors that may increase a baby’s risk of developing this birth defect.

The following risk factors are associated with craniocerebral disease:

  • Many babies during pregnancy, such as twins or triplets
  • Large head size in the uterus
  • Maternal thyroid disease
  • Mother smoking
  • Use of fertility treatments such as Clomid (clomiphene citrate)


Lambdoid craniosynostosis is often diagnosed by physical examination. Your doctor may also order imaging tests to confirm the diagnosis. This is especially true for this type of craniocerebral disease, as it can be similar to positional plagiocephaly, a benign condition.

Your doctor will examine your baby’s head in detail, feeling the area around his or her head along the lambdoid suture for a hard top. Your doctor will also take time to distinguish your child’s symptoms from positional plagiocephaly. For example, lambidoid craniocerebral disease gives the ears a retracted appearance, while positional plagiocephaly causes them to look pushed to the face.

Your doctor will also take a detailed history to find out about your family’s health history, in particular asking about any family members with a history of craniocerebral disease, skull abnormality or genetic disorders.

Your doctor may then recommend a CT scan of your baby’s head. Computed tomography (3D) reconstruction is the most accurate way to diagnose a lambid cranial gland. This test can show your baby’s lamboid suture ցանկացած any brain abnormalities.

Rarely, craniocerebral disease is presented as part of a genetic disorder. If your doctor suspects this is the case, they will order additional tests and may suggest a genetic test for the family.


Lambdoid craniosynostosis should be treated with surgery. The purpose of the operation is to correct the scalp, which will allow the brain to grow normally. There are two types of surgery to treat lambidoid craniocerebral disease. Your doctor will discuss both options with you to determine what is best for your baby.

Endoscopic cranial surgery

Endoscopic cranial surgery is a minimally invasive procedure available to infants before 6 months of age. During this procedure, your surgeon makes a few small incisions in your baby’s head, then uses a small tube, an endoscope, to move the skull bones more circularly.

This type of surgery should be performed at 2 to 6 months of age, as the skull bones are still soft enough and flexible enough to be molded with an endoscope.

After surgery, your baby should wear a cast helmet until his or her first birthday to keep his or her head growing normally. They will have to wear it for 24 hours, including while sleeping.

Calvarial Vault Remodeling:

Calvarial arch replacement is a more invasive surgery that is performed after your baby is 6 months old. During this procedure, the surgeon cuts off your baby’s head and moves the skull bones in a circle. This surgery can take up to six hours or may require a blood transfusion due to blood loss.

Calvarial arch remodeling is used in older infants because their skull bones are so thick that they can move to maintain their new appearance. Children who undergo this type of surgery do not have to wear a cast helmet afterwards.

Tim Schedule:

Lambdoid craniosynostosis can be diagnosed at birth or in the first year of your baby’s life. Treatment will depend on the age of the child at the time of diagnosis and the severity of the skull defects.

The schedule of diagnosis and treatment is as follows:

  • Irth up to 1 yearThe diagnostic process includes physical examination և CT scan with 3D reconstruction.
  • 2 to 6 monthsEndoscopic cranial surgery is recommended.
  • 6 to 12 months. Calorie arch conversion is recommended.


Lambdoid craniosynostosis can be treated with early diagnosis and surgery. When left untreated, a child may experience an increase in intracranial pressure. It occurs when the pressure inside the skull increases and affects the brain. This can lead to long-term complications, including:

  • Acceleration delays
  • Abnormalities of the head or face
  • Respiratory problems
  • Vision disorders
  • Seizures
  • Low self-esteem


It is incredibly difficult to hear the news that your baby has a serious birth defect և most likely needs skull surgery. Finding ways to cope with the Cope abortion is essential for parents and caregivers. Research shows that caring for a child with craniocerebral disease is stressful for parents, especially when their cranial defect is noticeable to others.

A 2020 study of parents of children with craniocerebral disease found that parents can take steps to reduce stress during treatment. As your child’s medical appointments can be overwhelming, try to write down any of your questions ahead of time so you don’t forget them. You can bring a pen or paper to take notes.

Ask your medical team who you can call between appointments. The nurses found that calling a specialist nurse helps reduce fear and stress about their baby’s condition. Finally, ask your child’s medical team about a local group or online community to join in support և education.


Lambdoid craniosynostosis is a rare type of craniocerebral disease that affects the lambdoid suture, a flexible joint that runs along the back of the head. This causes the baby’s head to rest on a flat back և, therefore, is usually confused with positional plagiocephaly, which is a favorable condition that occurs if the baby spends too much time lying on his back. Lambdoid craniosynostosis is treated with surgery; the sooner diagnosis and treatment begin, the better the outcome for the baby.
