Summary
Early cranioplasty for scaphocephaly improves skull shape but may not fully restore cognitive development. Early surgical intervention (within 1 month) might mitigate some developmental delays in children with this condition.
Area of Science:
- Pediatric Neurosurgery
- Developmental Neuroscience
- Craniofacial Surgery
Background:
- Scaphocephaly, a skull deformity due to premature sagittal suture fusion, is often treated with early cranioplasty.
- While cranioplasty normalizes skull shape and reduces intracranial pressure, its impact on neurocognitive outcomes remains unclear.
Purpose of the Study:
- To evaluate the long-term neurocognitive development of children treated for scaphocephaly with early cranioplasty.
- To compare the neurocognitive outcomes of these children with age- and gender-matched healthy controls.
Main Methods:
- Eighteen infants with scaphocephaly underwent cranioplasty between 1 week and 7 months of age.
- Patients were followed and neurocognitive development assessed at school age (7.8–16.3 years) using the Wechsler Intelligence Scale for Children-Revised.
Main Results:
- Children operated on for scaphocephaly exhibited mild deficits in auditory short-term memory and language development compared to controls.
- Overall developmental outcomes were comparable to controls in all other assessed neurocognitive domains.
Conclusions:
- Early cranioplasty for scaphocephaly does not fully normalize neurocognitive performance by school age, suggesting potential in-utero brain development impairment.
- Intervention within the first month of life may reduce developmental delays, supporting early surgery for both skull correction and brain development.
- Delaying surgery is not advisable as it may hinder both skull normalization and optimal brain development.
