Bilateral Coronal Synostosis

Bilateral coronal synostosis means both coronal sutures—the flexible seams running from ear to ear across the top of a baby’s skull—fuse too early. In a newborn and young infant, sutures are supposed to stay open to let the skull expand as the brain grows. When both coronal sutures close prematurely, the skull cannot grow forward in the normal front-to-back direction. Growth is pushed to the sides and upwards instead. The typical head shape becomes short from front to back (brachycephaly) and taller than usual (turricephaly/turribrachycephaly). Because the forehead cannot move forward, it looks flat; the sides of the head can appear full or bossed near the temples; and the eye sockets may be shallow, which can make the eyes look prominent. If the skull stays too tight while the brain is trying to grow, intracranial pressure can rise; this may affect vision, sleep, learning, and overall development if not recognized and treated early. In many children, bilateral coronal synostosis is part of a genetic syndrome (for example, FGFR-related conditions), but it can also occur by itself (non-syndromic). PMC+1HealthyChildren.org

Bilateral coronal synostosis means that both coronal sutures—the fibrous joints that run from ear to ear across the top of a baby’s skull—fuse too early. A baby’s skull has several movable plates connected by sutures. These sutures normally stay open through infancy and early childhood so the brain can grow. When both coronal sutures fuse prematurely, the skull cannot expand normally in the front-to-back direction. The head becomes short from front to back and wide from side to side, a shape called brachycephaly. The forehead may look flattened and sometimes tilted back, and the brow and eye sockets can appear prominent or shallow. Because the skull cannot expand easily, pressure inside the head can rise in some children, which may affect vision, sleep, breathing, and development if not addressed.

Types

You will see “types” used in a few different, practical ways:

1) By pattern of suture fusion

• Complete bilateral coronal synostosis: both coronal sutures are fused along most of their length. Head shape is classically brachycephalic; height may be increased (turricephaly). In severe cases, the skull may become very tall or even cloverleaf-shaped if other sutures join, especially in certain syndromes. NCBIOrpha

• Partial bilateral coronal synostosis: the coronal sutures are not fully fused end-to-end, but fusion occurs in key segments that still block front-to-back growth. Shape changes are similar but sometimes milder. PMC

2) By clinical context

• Isolated (non-syndromic): only the skull sutures are affected, with no consistent pattern of other body findings; many cases are sporadic. PMC

• Syndromic: skull fusion occurs with other features (hands, feet, midface, hearing, airway, etc.) due to a genetic condition (e.g., Apert, Crouzon, Pfeiffer, Muenke, Saethre-Chotzen, ERF-related, TCF12-related, craniofrontonasal, etc.). Syndromic cases more often involve both coronal sutures and sometimes multiple sutures. NCBIjkns.or.kr

3) By severity and growth impact

• Mild–moderate: frontal flattening and head shortening with limited or no pressure symptoms.

• Severe: marked turricephaly, shallow orbits with proptosis, early or progressive raised intracranial pressure, and sometimes multisuture fusion in syndromic forms. PubMed

Types

1. Nonsyndromic bilateral coronal synostosis
   Early fusion of both coronal sutures happens without other body differences or known syndrome. The main findings are the characteristic head shape, possible raised intracranial pressure (ICP), and sometimes vision or developmental concerns.

2. Syndromic bilateral coronal synostosis
   The synostosis occurs with other features (face, hands/feet, airway). Common genes and syndromes include FGFR2/FGFR3-related conditions (e.g., Apert, Crouzon, Pfeiffer), TWIST1 (Saethre-Chotzen), TCF12 (often coronal), EFNB1 (craniofrontonasal), POR (Antley-Bixler), MSX2, and others. Syndromic cases more often have midface hypoplasia, airway problems, eye exposure issues, hearing differences, and recurrent intracranial pressure.

3. Partial vs. complete fusion
   A suture can be fused along part of its length (partial) or along most of it (complete). Complete fusion usually causes more visible shape change and higher clinical urgency.

4. Early-presenting vs. late-recognized
   Some babies are identified in the newborn period; others are noticed later because of head shape or developmental issues.

5. Recurrent or persistent synostosis after surgery
   Rarely, a child who has had surgery can develop re-fusion or secondary synostosis of the same or other sutures; such cases require renewed evaluation.

Causes

Most causes involve gene changes (variants) in growth-signaling pathways that tell bone “how fast to become bone.” These changes push sutures to turn into bone too early. Below are 20 well-documented causes or cause-groups associated with bilateral coronal synostosis; the brief note explains what each means in practice.

1. FGFR3 p.Pro250Arg (Muenke syndrome): a single, well-known FGFR3 change; bilateral coronal is common; hearing issues and variable learning concerns can occur. Autosomal dominant. NCBIPubMedNORD

2. FGFR2 (Apert syndrome): often bicoronal with midface retrusion and syndactyly (fused fingers/toes). Autosomal dominant; many cases are new (de novo). NCBI

3. FGFR2 (Crouzon syndrome): craniosynostosis with shallow orbits and midface hypoplasia; coronal fusion often present and can be bilateral. NCBI

12. MSX2 (Boston-type craniosynostosis): autosomal dominant; variable suture involvement including coronal; caused by specific MSX2 mutations (e.g., P148H). PubMedJBC

13. Other FGFR-related syndromes (overview): FGFR pathway conditions as a group commonly feature bicoronal fusion in their spectrum. NCBI

14. Familial non-syndromic coronal synostosis: runs in families without other consistent features—genes like TCF12 or TWIST1 may be involved even if outward signs are limited. PMC

15. Maternal thyroid disease / thyroid hormone exposure (possible risk factor): epidemiologic and experimental studies suggest a link to craniosynostosis; the strength and suture-specificity vary across studies. PMCSpringerLinkPLOS

16. In-utero valproate exposure (possible association): some reports link prenatal valproate to craniosynostosis (often metopic), but risks vary by study and defect type. The Journal of NeuroscienceBioMed CentralNew England Journal of Medicine

17. General craniofacial developmental pathway variants (e.g., SMAD/TGF, WNT pathway research signals): research shows these pathways regulate suture biology; certain rare variants can contribute. Oxford Academic

18. ERF/ETS network influence on posterior fossa and Chiari: important clinically because multisuture disease can include coronal involvement and posterior crowding. PMC

19. Complex multisuture syndromes (e.g., Beare-Stevenson, Bent bone dysplasia) in the FGFR spectrum: rare, severe forms where coronal fusion is part of a broader pattern. NCBI

20. Undetermined / multifactorial: many cases—especially isolated ones—have no single identified cause despite modern testing; environment and subtle genetics likely interact. MDPI

3. Fullness at the temples (temporal bossing) with a “high” forehead contour. PubMed

4. Shallow eye sockets (orbital shallowing) leading to prominent-appearing eyes or true proptosis in syndromic cases. Medscape

5. Eyes that seem widely spaced or look “outward” because of orbit position; true hypertelorism varies by syndrome. NCBI

6. Eye movement problems (e.g., strabismus, V-pattern, or limited upgaze) due to orbital shape change and muscle imbalance. NCBI

7. Headaches, irritability, or vomiting in older infants/children—possible signs of raised intracranial pressure (ICP). PubMed

Diagnostic Tests

A) Physical Exam

1. Head shape inspection (front, side, top, and back): clinicians look for short front-to-back length, tall skull, temporal bossing, and forehead flattening typical of bilateral coronal fusion. This bedside exam is the starting point and often strongly suggests the diagnosis. PubMed

2. Palpation of sutures and fontanelle: feeling for a ridge along the coronal sutures and a small/early-closed soft spot. PMC

3. Head-growth charting (occipitofrontal circumference, OFC): tracking growth over time; a plateau or mismatch with expected curves can raise concern for restricted skull expansion. MDPI

4. Neurologic and developmental screening: tone, reflexes, milestones, language and behavior to screen for effects of raised ICP or syndromic involvement. PubMed

5. Eye exam with fundoscopy (looking at the optic discs): checks for papilledema (swelling) as an indirect sign of raised ICP. PubMed

B) Manual / Bedside Measurements

6. Cranial index calculation (ratio of width to length) with simple calipers or flexible tape: bilateral coronal synostosis usually shows increased cranial index due to shortened length. MDPI

7. Inter- and outer-canthal distance measurement (eye spacing) to document hypertelorism or orbital effects where present. NCBI

8. Cover–uncover and Hirschberg tests for strabismus at the bedside: simple checks for eye alignment and tracking that are useful in clinic. NCBI

9. Anthropometric facial measurements (midface retrusion, orbital depth estimation) to capture severity and follow change over time—useful in syndromic cases. Medscape

C) Lab and Pathology / Genetic Testing

10. Targeted gene testing for FGFR3 p.Pro250Arg (Muenke) when bilateral coronal synostosis is suspected, especially with hearing concerns or family history. NCBI

11. FGFR2 and FGFR1 testing (Apert, Crouzon, Pfeiffer) when features suggest these syndromes (syndactyly, midface retrusion, broad thumbs/toes). NCBIBioMed Central

12. TWIST1 and TCF12 testing for familial or apparently isolated coronal synostosis (uni- or bilateral); both are frequent causes. NCBIPMC

13. Expanded craniosynostosis gene panel / exome including ERF, EFNB1, POR, RAB23, MSX2, RECQL4 and others when the first-line targets are negative or features are atypical. PMC+1PubMed

Notes: Lab work like thyroid function may be considered when there’s a clinical reason (e.g., maternal thyroid treatment history), but genetic testing explains most bilateral coronal cases that are not obviously positional or secondary. PMC

D) Electrodiagnostic / Physiologic Studies

14. Polysomnography (sleep study) to assess obstructive sleep apnea, which is common in several craniosynostosis syndromes with midface narrowing. Medscape

15. Visual evoked potentials (VEP) when there are concerns about optic nerve function (e.g., suspected pressure-related visual pathway compromise). PubMed

16. Intracranial pressure monitoring (selected, specialized cases): direct assessment when symptoms and imaging suggest raised ICP and the decision will guide urgent management. PMC

E) Imaging

17. Cranial ultrasound (CUS) in young infants: a radiation-free screening tool through the fontanelle to look at sutures; sensitivity varies and depends on expertise. Often used when suspicion is moderate. PMCThieme

18. Low-dose 3D CT of the skull (gold-standard confirmation): clearly shows suture fusion and overall skull/orbit shape, and helps plan surgery; modern protocols minimize radiation. PMC

19. MRI of brain and posterior fossa (selected cases): evaluates brain development, venous sinuses, and Chiari I risk—especially in ERF-related or multisuture disease. PMC

20. 3D surface photography / stereophotogrammetry for objective head-shape tracking over time; helpful for documentation and outcome measurement. Nature

Drug Treatments

There is no medicine that “unfuses” a suture. Medicines are used to control symptoms, protect the eyes/brain, and support surgery. Doses below are typical pediatric ranges for general education only; always follow your child’s specialist’s exact prescription.

1. Acetaminophen (Paracetamol) – Analgesic/antipyretic
   Dosage: 10–15 mg/kg per dose by mouth every 4–6 hours (do not exceed max daily dose per pediatric guidance).
   Purpose: Pain and fever control, especially after surgery.
   Mechanism: Central COX inhibition reduces pain/fever.
   Side effects: Rare when dosed correctly; overdose can harm the liver.

2. Ibuprofen – NSAID (for infants ≥6 months unless surgeon advises otherwise)
   Dosage: 5–10 mg/kg per dose by mouth every 6–8 hours with food.
   Purpose: Pain/inflammation control.
   Mechanism: COX inhibition reduces prostaglandins.
   Side effects: Stomach upset, kidney strain, bleeding risk; surgeons may limit right before/after surgery.

3. Topical ocular lubricants (artificial tears/ointments)
   Dosage: As prescribed (drops daytime; ointment at bedtime).
   Purpose: Protect the cornea in shallow orbits/exposure.
   Mechanism: Stabilizes tear film.
   Side effects: Temporary blur/irritation (ointment).

4. Antibiotic prophylaxis (e.g., cefazolin) – perioperative
   Dosage: Typical IV 25–30 mg/kg at induction; redose per anesthesia protocol.
   Purpose: Reduce surgical site infection.
   Mechanism: Bactericidal cell wall inhibition.
   Side effects: Allergic reactions, GI upset.

5. Nasal saline sprays/drops
   Dosage: Few drops/sprays per nostril as needed.

Dietary “Molecular” Supplements

Supplements do not reverse fused sutures. Nutrition supports overall growth, healing, and brain/eye health. Use only age-appropriate products and avoid megadoses. Always confirm with your pediatrician.

1. Vitamin D
   Dose: Common infant prophylaxis is 400 IU/day (country-specific guidelines).
   Function/Mechanism: Supports calcium balance and bone mineralization; secures healthy skeleton during rapid growth.

2. Calcium (diet first)
   Dose: Meet daily intake via breast milk/formula/foods; supplements only if prescribed.
   Function: Bone mineral; works with vitamin D.

3. Iron
   Dose: Supplements only if deficient (typical preventive 1 mg/kg/day elemental in certain infants; treatment doses differ).
   Function: Hemoglobin and brain development; low iron worsens fatigue and development.

4. Iodine
   Dose: Provided by iodized salt/maternal diet; separate supplements usually unnecessary if diet adequate.
   Function: Thyroid hormone production; extreme deficiency or excess can disturb growth.

5. DHA (omega-3)
   Dose: Provided by breast milk/infant formula; consider maternal intake if breastfeeding (fish 1–2×/week, low-mercury).
   Function: Neural and retinal development.

6. Folate (maternal)
   Dose: 400–800 mcg/day per preconception/prenatal guidance.
   Function: Neural tube and craniofacial development in early pregnancy.

7. Zinc (diet first)
   Dose: Only if deficient; pediatric dosing individualized.
   Function: Cell growth, wound healing, immune enzyme function.

8. Probiotics (select strains)
   Dose: Product-specific; discuss with pediatrics.
   Function: May support GI health during antibiotics; not cranial-specific.

9. Vitamin C
   Dose: Achieve via fruits/vegetables; supplements only if needed.
   Function: Collagen formation and wound healing.

10. Protein-rich nutrition
    Dose: Diet-based via appropriate formula/foods.
    Function: Tissue repair after surgery; supports growth.

Avoid high-dose vitamin A/retinoids—teratogenic in pregnancy. Avoid unregulated “bone” or “stem cell” supplements.

Regenerative/Stem Cell” Drugs

There are no approved “immunity booster,” regenerative, or stem cell drugs that treat or reverse bilateral coronal synostosis in infants or children. Research in animals explores FGF/MAPK pathway modulation and tissue engineering, but these are experimental, not standard of care, and not available outside clinical trials. For completeness:

1. FGFR pathway inhibitors (research stage) – aim to dampen overactive signaling that drives bone formation at sutures; not approved for pediatric synostosis.

2. MEK/ERK pathway modulators (preclinical) – target downstream of FGFR; experimental only.

3. BMP/TGF-β signaling modulators (preclinical) – theoretical control of osteoblast activity; not in clinical use.

4. Local biologics to delay bone formation (animal models) – not approved for infants.

5. Stem-cell–based bone tissue engineering – investigated for cranial defects after surgery, not for unlocking fused sutures; experimental.

6. Gene-targeted therapies – conceptual stage for specific monogenic syndromes; no clinical therapy for coronal synostosis today.

Bottom line: Surgery remains the definitive, evidence-based treatment. Families should be cautious about any clinic or product claiming to “cure synostosis without surgery.”

Surgeries

1. Endoscopic suturectomy with postoperative helmet therapy
   Procedure: Through small incisions, surgeons remove the fused suture segments using an endoscope; the baby then wears a custom helmet for months to guide growth.
   Why: Early (often 2–4 months) option with less blood loss and shorter hospital stay; relies on rapid brain growth + helmet to reshape skull.

2. Fronto-orbital advancement (FOA)
   Procedure: Surgeons reshape and advance the forehead bone and the upper eye socket (orbital bandeau).
   Why: Create room for the brain, protect the eyes, correct forehead/orbit shape; common in bilateral coronal cases, especially when older at diagnosis.

3. Cranial vault remodeling (CVR)
   Procedure: Larger open surgery to reshape the skull bones; can include the front, sides, or multiple areas.
   Why: Expand intracranial volume, normalize head shape, and reduce ICP risk.

4. Distraction osteogenesis (selected centers)
   Procedure: After cutting bone, devices slowly distract (separate) bone segments to create new bone and expand volume.
   Why: Controlled expansion with less acute movement; useful in complex or recurrent cases.

5. Monobloc or Le Fort III midface advancement (syndromic)
   Procedure: Move the forehead/orbits (monobloc) or midface (Le Fort III) forward, sometimes with distraction devices.
   Why: Increase airway and orbit volume, protect eyes, improve bite/sleep in syndromic children with midface hypoplasia.

Timing depends on age, severity, syndrome, and ICP/eye findings. The craniofacial team will explain risks (bleeding, infection, reoperation, relapse, transfusion) and expected benefits.

Prevention

You cannot guarantee prevention of coronal synostosis. These steps promote healthy pregnancy and infant development and reduce avoidable risks.

1. Preconception folic acid (400–800 mcg/day) and balanced prenatal vitamins.

2. Avoid retinoid drugs/high-dose vitamin A in early pregnancy unless essential and specialist-supervised.

3. Manage maternal thyroid disease prior to and during pregnancy.

4. Avoid alcohol, tobacco, and illicit drugs during pregnancy.

5. Discuss antiepileptic medicines with specialists before pregnancy; never stop needed meds abruptly.

6. Use iodized salt and maintain iodine-adequate diet during pregnancy.

7. Regular prenatal care and ultrasounds to monitor fetal growth and amniotic fluid.

8. Healthy maternal diet and weight gain per obstetric guidance.

9. Space pregnancies and treat infertility under specialist care; discuss any observed risks.

10. Newborn and well-baby visits for early detection of head shape concerns.

When to See Doctors

• Immediately/urgently: bulging soft spot (if still open), persistent vomiting, listlessness, seizures, fever with wound redness/swelling after surgery, rapidly worsening eye redness or apparent pain with light.

• Promptly (soon): eyes looking more prominent or not closing fully, new or worsening strabismus, frequent headaches (older child), snoring/pauses in sleep, poor weight gain, developmental regression, head shape changing rapidly, helmet problems after endoscopic surgery.

• Routinely: all scheduled craniofacial, ophthalmology, ENT, therapy, and pediatric growth visits—even if your child seems well.

---

What to Eat and What to Avoid

For infants:

• Breast milk or iron-fortified formula on demand with normal volumes guided by your pediatrician.

• Vitamin D supplementation as locally recommended.

• Introduce solids around 6 months if developmentally ready, focusing on iron-rich foods (meat, iron-fortified cereals), vegetables, fruits, yogurt, legumes.

• Avoid: honey before age 1, choking hazards, excess juice/sugar, and any unproven supplements marketed to “fix skull shape.”

For toddlers/children:

• Balanced plate: fruits, vegetables, whole grains, proteins, dairy as tolerated.

• Hydration with water and milk; limit sugar-sweetened drinks.

• Include fish (low-mercury) once or twice weekly for DHA (if not allergic).

• Avoid ultra-processed snacks as staples, excess vitamin A, and any “bone growth boosters” not recommended by your clinician.

For breastfeeding parents:

• Eat a varied diet; take prenatal/postnatal vitamins as advised; keep iodine and DHA adequate; avoid high-mercury fish and alcohol.

Frequently Asked Questions

1. Can a helmet alone fix bilateral coronal synostosis?
   No. Helmets guide growth after an endoscopic suture release. A helmet does not reopen a fused suture.

2. Will my child’s brain be okay?
   Many children do very well, especially with early diagnosis, appropriate surgery, and regular follow-up. The team watches closely for ICP and vision issues.

3. Is surgery always required?
   In most bilateral coronal cases, yes, because both front sutures are fused and there’s a higher risk of restricted growth/ICP. The exact plan is individualized.

4. What is the best age for surgery?
   Endoscopic procedures often at 2–4 months; open FOA/CVR commonly around 6–12 months or later if diagnosed late. Your team will tailor timing.

5. Will my child need more than one surgery?
   Possibly—especially in syndromic cases or if there is re-fusion or new suture fusion. Regular surveillance guides decisions.

6. How will we know if pressure is high?
   Symptoms (irritability, vomiting, headaches), eye exams (papilledema), imaging, and sometimes pressure monitoring inform the team.

7. Can exercises or massages open sutures?
   No. Exercises help neck mobility and development, but do not reverse fusion.

8. Could glasses or eye surgery be needed?
   Sometimes. Strabismus or refractive errors may need treatment to protect vision.

9. Is this my fault?
   No. Most cases are not caused by parenting. Some are genetic; many are idiopathic.

10. Will my next baby have it?
    Recurrence risk depends on the cause. With a known gene variant, risk can be higher; with no identified cause, risk is usually low. Genetic counseling helps quantify risk.

11. Are there medicines that melt the bone or “unlock” sutures?
    No approved medicines do this today.

12. Is CT safe for my infant?
    Modern low-dose protocols are designed to minimize radiation. Teams use imaging only when necessary.

13. How long is recovery after surgery?
    Varies by procedure. Endoscopic cases often have shorter stays; open cranial vault surgeries have longer recovery. Your team provides a detailed plan.

14. Will my child look “normal” after surgery?
    Many children have excellent cosmetic outcomes. The goal is brain/eye safety first, then shape. Some may need later refinements.

15. What can we do at home to help?
    Keep follow-up appointments, protect the eyes, support good sleep/nutrition, use helmet exactly as prescribed (if applicable), and seek help early for any new concerns.
