Metopic Synostosis: Causes, Signs, and Treatment
Metopic synostosis is a type of craniosynostosis, a condition where the bones in an infant's skull fuse together too early. This premature fusion affects the normal growth of the skull and brain, potentially leading to changes in the shape of the head and face. In severe cases, metopic synostosis can impact the development of the brain and may cause complications related to vision, breathing, and cognitive function. Early detection and appropriate management are essential to address the potential health implications associated with this condition.
Symptoms of Metopic Synostosis
Metopic synostosis can lead to noticeable changes in a child's head shape and facial features.
- Abnormal head shape
- Narrow forehead
- Widely spaced eyes
- Prominent ridge on the forehead

Get Second OpinionCauses of Metopic Synostosis
Metopic synostosis is primarily caused by the premature fusion of the frontal bone plates in the skull during infancy, leading to an abnormal skull shape and potential developmental issues.
- Genetic factors
- Environmental factors
- Abnormal development of the skull bones
Types of Metopic Synostosis
Metopic synostosis can manifest in various forms, each affecting the growth and shape of the skull differently.
- Simple Metopic Synostosis: The most common type where the metopic suture fuses prematurely at the top of the forehead.
- Complex Metopic Synostosis: Involves additional cranial sutures fusing prematurely along with the metopic suture, leading to more severe skull deformities.
- Mild Metopic Ridge: A less severe form where a noticeable ridge forms along the forehead due to partial fusion of the metopic suture.
- Severe Metopic Ridge: Characterized by a pronounced ridge or keel along the forehead resulting from significant fusion of the metopic suture.
- Metopic Craniosynostosis with Associated Syndromes: Occurs in conjunction with certain genetic syndromes, leading to complex craniofacial abnormalities along with metopic suture fusion.
Risk Factors
Metopic synostosis risk factors may include genetic predisposition, premature birth, and certain environmental factors.
- Genetic predisposition
- Premature birth
- Male gender
- Maternal smoking during pregnancy
- Maternal age over 35
- Multiple gestation (twins, triplets)
- Certain medications taken during pregnancy
- Exposure to environmental toxins

Diagnosis of Metopic Synostosis
Metopic synostosis is typically diagnosed through a combination of physical examination and medical imaging.
- Physical Examination
- Skull Xray
- CT Scan
- MRI Scan
- Genetic Testing
Treatment for Metopic Synostosis
Metopic synostosis is typically treated with interventions that aim to correct the abnormal skull growth and shape in affected individuals.
Surgical Correction:
- Surgical correction is the primary treatment for Metopic Synostosis, involving the release of the prematurely fused skull bones to allow for normal growth and development of the skull shape.
Postoperative Helmet Therapy:
- Postoperative helmet therapy may be recommended after surgery to help mold and shape the skull as it continues to grow, promoting optimal aesthetics and function.
Monitoring and Followup Care:
- Regular monitoring and followup care are essential to track the progress of the skull growth and ensure early detection of any complications that may arise postsurgery.
Physical Therapy:
- Physical therapy may be beneficial to aid in the recovery process postsurgery and to address any developmental delays or motor function issues that may arise.
Multidisciplinary Team Approach:
- A multidisciplinary team approach involving various specialists such as neurosurgeons, plastic surgeons, and pediatricians is crucial for comprehensive care and management of Metopic Synostosis.

What is Metopic Synostosis?
Metopic Synostosis is a type of craniosynostosis where the metopic suture in the skull fuses prematurely, leading to abnormal skull shape.
What are the symptoms of Metopic Synostosis?
Symptoms may include a triangularshaped forehead, closely spaced eyes, a ridge running down the forehead, and potential developmental delays.
How is Metopic Synostosis diagnosed?
Diagnosis is usually made through physical examination, imaging tests like CT scans, and sometimes genetic testing.
What are the treatment options for Metopic Synostosis?
Treatment may involve surgery to release the fused suture and reshape the skull to allow for normal brain growth.
What is the longterm outlook for individuals with Metopic Synostosis?
With early diagnosis and appropriate treatment, most individuals can have positive outcomes with normal brain development and minimal longterm complications.
