Long-term mental outcomes for children with trigonocephaly depend on several factors. Severe frontal stenosis, delayed surgery, and extracranial malformations negatively impact development, while family environment plays a crucial role.

Area of Science:

  • Pediatric Neurosurgery
  • Developmental Neuroscience
  • Clinical Genetics

Background:

  • Trigonocephaly, a premature fusion of the coronal and metopic sutures, can lead to significant neurodevelopmental challenges.
  • Understanding the long-term mental outcomes and prognostic factors is crucial for effective clinical management.
  • Previous studies have explored various aspects, but a comprehensive assessment of factors influencing mental development in operated children is needed.

Purpose of the Study:

  • To assess the long-term mental outcome in children surgically treated for trigonocephaly.
  • To identify factors influencing the mental development and prognosis in this patient cohort.

Main Methods:

  • Longitudinal assessment of 76 children operated on for trigonocephaly, with final evaluation after 3 years of age.

  • Assessment included behavioral disturbances, learning disabilities, school difficulties, and intellectual efficiency.
  • Preoperative CT scans analyzed frontal stenosis severity and intracranial abnormalities; extracranial malformations and family history were also recorded.

    • Main Results:

    • 31.6% of patients exhibited some degree of mental abnormality.
    • Worse mental development correlated with severe frontal stenosis, cranial reconstruction after one year of age, and associated extracranial malformations.
    • Family environment significantly influenced outcomes, whereas intracranial abnormalities did not show a correlation.

    Conclusions:

    • Surgical timing, severity of stenosis, and presence of extracranial anomalies are key predictors of mental outcome in trigonocephaly.
    • The family environment is a critical factor in the long-term neurodevelopmental trajectory.
    • Early surgical intervention and management of associated conditions may improve long-term prognosis.
