Sagittal Synostosis: Causes, Signs, and Treatment
Sagittal synostosis is a condition where the sagittal suture, a fibrous joint that connects the two parietal bones of the skull, fuses prematurely. This fusion restricts normal skull growth in the affected area, leading to changes in head shape and potentially impacting brain development. The primary impact of sagittal synostosis on health is related to the distortion of the skull shape, which can affect overall well-being and potentially lead to complications if not addressed.
What are the Symptoms of Sagittal Synostosis
Sagittal synostosis is a condition where the skull's sagittal suture fuses prematurely. This can lead to noticeable changes in the shape of the head. Children with this condition may exhibit specific symptoms related to the skull shape and development. Detecting these signs early can aid in timely intervention and treatment by healthcare providers.
- Abnormal head shape
- Raised ridges along the skull
- Difficulty feeding
- Delayed development
- Increased intracranial pressure
- Sleep disturbances

Get Second OpinionCauses of Sagittal Synostosis
Sagittal synostosis, a type of craniosynostosis, occurs when the main suture at the top of a baby's head fuses prematurely. This fusion restricts normal skull growth, leading to a long, narrow head shape.
The causes of sagittal synostosis can be genetic or due to external factors. Understanding these causes is crucial for early diagnosis and appropriate treatment to ensure optimal outcomes for affected infants.
- Genetics
- Positional Plagiocephaly
- Premature fusion of the sagittal suture
- Environmental factors
- Unknown factors
Types of Sagittal Synostosis
Sagittal synostosis is a type of craniosynostosis that affects the growth of a baby's skull. There are different forms of sagittal synostosis, each with its own characteristics and impact on skull development. Understanding the various types of sagittal synostosis can help healthcare providers diagnose and manage this condition effectively.
- Primary Sagittal Synostosis: This is the most common type of sagittal synostosis where the sagittal suture fuses prematurely, leading to an elongated skull shape.
- Secondary Sagittal Synostosis: This occurs as a result of craniosynostosis surgery or other factors that cause the sagittal suture to close prematurely after birth.
- Syndromic Sagittal Synostosis: In this type, sagittal synostosis is associated with genetic syndromes like Apert syndrome or Crouzon syndrome, leading to more complex skull abnormalities.
- Isolated Sagittal Synostosis: This type involves only the sagittal suture fusion without any other cranial abnormalities, often requiring surgical intervention for correction.
- Complex Sagittal Synostosis: This type involves multiple sutures being fused, complicating the treatment approach and requiring a multidisciplinary team for optimal management.
Risk Factors
Sagittal synostosis is a condition where the sagittal suture, the main suture on the top of the skull, fuses prematurely. This fusion can lead to abnormal skull growth. Several factors can increase the risk of a baby developing sagittal synostosis.
Risk Factors for Sagittal Synostosis:
- Genetic predisposition
- Male gender
- Advanced paternal age
- Multiple gestation (twins, triplets)
- Certain genetic syndromes (e. g.
- Environmental factors (e. g.
- , maternal smoking during pregnancy)
- , Apert syndrome)

Diagnosis of Sagittal Synostosis
Sagittal synostosis is typically diagnosed through a combination of physical examination and imaging tests. During a physical exam, a healthcare provider will look for signs such as an elongated head shape or a ridge along the skull.
- Physical examination
- Skull Xray
- CT scan
- Genetic testing
Treatment for Sagittal Synostosis
Sagittal synostosis is a condition where the skull bones fuse prematurely, affecting head shape and growth. Treatment options include observation, helmet therapy, and surgery. Observation may be recommended for mild cases, while helmet therapy can help reshape the skull in some infants.
In more severe cases or if other complications arise, surgery to correct the fusion may be necessary. Treatment decisions are based on the individual child's specific needs and the advice of healthcare providers.
- Surgery: The primary treatment for Sagittal Synostosis involves a surgical procedure called cranial vault remodeling to reshape the skull and allow for normal brain growth.
- Helmet Therapy: Some cases of Sagittal Synostosis may be managed with helmet therapy, where a specialized helmet is worn to help mold the shape of the skull over time.
- Regular Monitoring: Close monitoring by a healthcare provider is essential to track the progression of the condition and determine the need for intervention.
- Physical Therapy: Physical therapy may be recommended to aid in the development of motor skills and address any musculoskeletal issues associated with Sagittal Synostosis.
- Occupational Therapy: Occupational therapy can help improve handeye coordination, fine motor skills, and overall functional abilities in children with Sagittal Synostosis.
