Lambdoid Synostosis: Symptoms and Risks

Lambdoid synostosis is a condition where the lambdoid suture in the skull fuses prematurely, affecting the growth pattern of the head. This can lead to changes in the shape of the skull and potentially impact brain development. The primary impact of lambdoid synostosis on health is related to the structural changes it causes in the skull, which can affect overall head shape and potentially lead to issues with brain growth and development.

What are the Symptoms of Lambdoid Synostosis

Lambdoid synostosis can present with distinct signs and symptoms related to the premature fusion of certain cranial bones.

Misshapen skull
Abnormal head shape
Developmental delays
Increased intracranial pressure
Seizures
Vision problems

Causes of Lambdoid Synostosis

Lambdoid synostosis typically occurs due to the premature fusion of the lambdoid suture at the back of the skull, leading to abnormal head shape and potential neurological issues.

Genetic factors
Positional factors during pregnancy
Abnormal pressure on the infant's skull

Types of Lambdoid Synostosis

Lambdoid synostosis can present in various forms, affecting the back of the skull and potentially leading to head shape abnormalities in infants.

Primary Lambdoid Synostosis:

This type involves premature fusion of the lambdoid suture, impacting skull growth and shape.

Secondary Lambdoid Synostosis:

Occurs as a result of trauma, infection, or surgery, leading to early closure of the lambdoid suture.

Syndromic Lambdoid Synostosis:

Associated with genetic syndromes like Crouzon syndrome or Apert syndrome, affecting skull development.

Unilateral Lambdoid Synostosis:

Involves fusion on one side of the lambdoid suture, causing asymmetrical skull growth.

Bilateral Lambdoid Synostosis:

Fusion of both sides of the lambdoid suture, impacting overall skull shape and development.

Risk Factors

Lambdoid synostosis risk factors may include genetic predisposition, premature birth, and certain syndromes.

Genetic factors
Family history of craniosynostosis
Abnormal head shape at birth
Premature birth
Multiple pregnancies

Diagnosis of Lambdoid Synostosis

Lambdoid synostosis is typically diagnosed through a combination of physical examination and imaging tests.

Physical examination
Skull Xrays
CT scan
MRI scan

Treatment for Lambdoid Synostosis

Lambdoid synostosis is typically managed through specialized medical care to address the premature fusion of the lambdoid suture.

Surgery: Surgical intervention is the primary treatment for Lambdoid Synostosis, involving the removal of the fused suture to allow for normal skull growth and shape development.
Helmet Therapy: Helmets may be used postsurgery to help reshape the skull and provide additional support for optimal head growth in infants with Lambdoid Synostosis.
Physical Therapy: Physical therapy can be beneficial in improving motor skills and addressing any developmental delays that may result from Lambdoid Synostosis.
Monitoring and followup: Regular monitoring by a healthcare provider is essential to track the progress of treatment and ensure proper head growth in children with Lambdoid Synostosis.
Counseling and support: Providing emotional support and counseling to both the child and family members can be helpful in coping with the challenges of Lambdoid Synostosis and the treatment process.
