What is the recommended treatment for a pediatric patient under 5 years old with craniosynostosis?

Treatment of Craniosynostosis in Pediatric Patients Under 5 Years

Surgical intervention during the first year of life is the recommended treatment for craniosynostosis, with the choice between open cranial vault remodeling, strip craniectomy, or spring-assisted cranioplasty depending on the specific suture involved, patient age, and presence of increased intracranial pressure. 1, 2, 3

Initial Diagnostic Approach

Clinical examination alone is sufficient for diagnosis in the vast majority of cases. 4, 1 The diagnosis of craniosynostosis is strictly clinical and does not require routine imaging. 4

Key Clinical Findings to Document:

• Head shape abnormality specific to the fused suture (e.g., scaphocephaly for sagittal, trigonocephaly for metopic, plagiocephaly for unicoronal) 3
• Serial head circumference measurements until age 5 years—insufficient increase suggests craniosynostosis 4, 5
• Fundoscopic examination at every visit to evaluate for papilledema indicating increased intracranial pressure 4, 1, 5
• Neurological examination including assessment for developmental delays 1
• Signs of Chiari malformation or intracranial hypertension (headaches, visual changes) 4, 5

Imaging Strategy

Reserve imaging for equivocal clinical findings or confirmed craniosynostosis requiring surgical planning. 4, 1

• Ultrasound is often sufficient for suspected cranial suture anomalies when clinical examination is equivocal 4, 1
• CT or CBCT is indicated only for treatment planning in confirmed cases, not as a routine diagnostic tool 4, 1
• Avoid routine CT scanning due to radiation risks and cancer risk in developing children 1
• MRI plays no role in diagnosing craniosynostosis itself but is indicated when evaluating for associated intracranial complications like Chiari malformation 1, 6

Referral Pathway

Refer to pediatric neurosurgery when craniosynostosis is confirmed or highly suspected clinically. 4, 1

Specific Referral Indications:

• Confirmed craniosynostosis on clinical examination 4, 1
• Signs of increased intracranial pressure (papilledema, developmental delays, headaches) 1, 5
• Syndromic features present (requires referral to nationally designated craniofacial centers) 1, 5
• Congenital malformations of skull structures including deformational plagiocephaly or craniosynostosis 4

For syndromic craniosynostosis, a multidisciplinary craniofacial team with central coordinator is mandatory, including neurosurgery, genetics, ophthalmology, and other specialists. 5

Surgical Treatment Options

Three major surgical techniques are available, with optimal timing ideally in the first year of life: 3, 7

1. Open Cranial Vault Remodeling

• Traditional approach with mortality <1% and low complication rates (1.2%) and reoperation rates (2.5%) in contemporary series 8, 3
• Mean estimated blood loss 75-175 mL with mean hospital stay of 4.3 days 8
• Preferred for complex cases and syndromic craniosynostosis 2, 8

2. Strip Craniectomy

• Less invasive suturectomy-based technique 2, 7
• Best performed early in infancy (typically 0-6 months) 7

3. Spring-Assisted Cranioplasty

• Newer minimally invasive option 2, 3
• Requires second procedure for spring removal 7

Age-Specific Surgical Timing

Surgery is ideally performed in the first year of life: 3, 7

• 42% of patients treated at 0-6 months 8
• 32% treated at 7-12 months 8
• 26% treated at 12 months or older 8

Follow-Up Requirements

Children with craniosynostosis require structured long-term monitoring: 4, 5

• Every 3 months during phases of rapid growth (infancy and puberty) or after initiation of therapy 4
• Every 6 months for patients demonstrating positive response to treatment or in stable condition 4
• Annual neurological assessment for all patients with known craniosynostosis 4, 5
• Twice-yearly dental visits after tooth eruption to prevent dental infections and periodontitis 4, 5
• Monitor for hearing loss, spine deformity, scoliosis, and maxillary dysmorphosis 4

Critical Pitfalls to Avoid

• Do not perform routine X-rays or CT scans for diagnosis—clinical examination is sufficient 4, 1
• Do not miss syndromic craniosynostosis—these cases require specialized craniofacial center referral, not general neurosurgical care 1, 5
• Do not delay fundoscopic examination—papilledema indicates urgent need for intervention 4, 1, 5
• Do not confuse positional plagiocephaly with craniosynostosis—positional plagiocephaly improves with repositioning and does not require surgery 1

Expected Outcomes

School-age children with treated craniosynostosis have subtle but lower cognitive and behavioral performance on average, though patient-reported quality of life outcomes are comparable to control individuals. 3 The neurocognitive impact is an area of active research, and optimal surgical timing continues to be studied. 7
