AI Article Synopsis
- The study investigates the impact of reoperation on neurocognitive outcomes in children with nonsyndromic sagittal craniosynostosis who underwent whole-vault cranioplasty, but the optimal age for surgery remains unclear.
- Among the 47 school-age participants, 27.7% required reoperation, primarily for minor revisions, with no significant difference in reoperation rates based on the timing of initial surgery.
- While reoperated patients who had surgery at an earlier age showed better neurocognitive scores in areas like IQ and academic achievement, overall, there was no significant difference in cognitive outcomes between reoperated and nonreoperated individuals.
Article Abstract
Introduction: Optimal age at surgery in nonsyndromic sagittal craniosynostosis continues to be debated. Previous reports suggest that earlier age at whole vault cranioplasty more frequently requires reoperation. It is unknown, however, whether reoperation affects neurocognitive outcome. This study examined the impact of reoperation on neurocognitive outcome in children with nonsyndromic sagittal craniosynostosis using comprehensive neurocognitive testing.
Methods: Forty-seven school-age children (age 5-16 years) with nonsyndromic sagittal craniosynostosis who underwent whole-vault cranioplasty were included in this analysis. Participants were administered a battery of standardized neuropsychological testing to measure neurocognitive outcomes.
Results: Thirteen of the 47 participants underwent reoperation (27.7%); 11 out of the 13 reoperations were minor revisions while 2 reoperations were cranioplasties. Reoperation rate was not statistically different between patients who had earlier surgery (at age ≤6 months) versus later surgery (at age >6 months) (P > 0.05). Nonreoperated patients who had only one later-in-life surgery did not perform statistically better than reoperated patients on any outcome measure of neurocognitive function, including IQ, academic achievement, visuomotor integration, executive function, and behavior. Comparing reoperated earlier surgery patients with nonreoperated later surgery patients, reoperated earlier surgery patients had higher full-scale and verbal IQ (P < 0.05), scored higher on word reading, reading comprehension, spelling, numerical operations, and visuomotor integration (P < 0.05), and had fewer indicators of suspected learning disabilities (P < 0.01) compared to nonreoperated later surgery patients.
Conclusion: Reoperation rate after whole vault cranioplasty was 27.7%, with few cases of repeat cranioplasty (4.2% of all patients). Reoperation was not associated with worse neurocognitive outcome. Reoperated earlier surgery patients in fact performed better in IQ, academic achievement and visuomotor integration when compared to nonreoperated later surgery patients.

Craniosynostosis is the premature fusion of one or more skull vault sutures, most commonly the sagittal sutures, leading to a long, narrow head shape known as scaphocephaly. Surgery is recommended to create space for brain growth to treat scaphocephaly. Delayed treatment may require more complex surgery to achieve the desired head shape.

Background: Craniosynostosis (CS) is defined as the premature fusion of cranial sutures and can be classified as nonsyndromic or syndromic and by which sutures are affected. It affects 1 in 2,000-2,500 children. The most common clinical feature in CS is an abnormal head shape.

Objective: We assessed the prevalence of guardian-reported reading difficulties in children treated for non-syndromic craniosynostosis (NSC) and in relation to the location of the closed suture. Additionally, we determined correlations with guardian-reported neurodevelopmental disorders (NDDs) and associations between reported reading ability, sex, timing of surgical intervention, parental education, and heredity of reading difficulties in guardians.

The aim of this study was to determine the impact of helmet therapy (HT) as a treatment for craniosynostosis, with a focus on the outcomes of skull morphology, reoperation rate, complications of HT, and quality of life of patients who receive it. A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review utilized the PICO format: Does HT following strip craniectomy (SC) improve outcomes (outcome) compared to SC alone (comparison) in patients undergoing craniosynostosis correction (intervention)? Searches were performed from January 1, 2000 to December 31, 2022, using PubMed, Cochrane Library, and Ovid Medline databases.

Article Synopsis
- - Anorectal malformations (ARM) are rare congenital defects occurring in about 3.32 per 10,000 pregnancies, involving a range of issues from mild anal canal displacement to severe fusion of the anorectum, vagina, and urethra.
- - The developmental basis of ARM stems from improper septation of the hindgut during early pregnancy, with most cases being non-syndromic and lacking clear genetic causes.
- - Surgical correction, primarily through posterior sagittal anorectoplasty since 1982, is common, but there is a need for further improvements in surgery outcomes, prenatal detection, and understanding the psychosocial impacts on patients.
