IQ Normal in Most Kids with Cranial Expansion Surgery

More than three-quarters with syndromic craniosynostosis have average intellectual capacities

MONDAY, July 31 (HealthDay News) -- Among children who underwent cranial expansion surgery as infants for syndromic craniosynostosis, 77 percent demonstrated normal intelligence, according to the results of a study published in the July issue of Plastic and Reconstructive Surgery.

John G. Meara, M.D., of the University of Melbourne in Victoria, Australia, and colleagues studied intellectual evaluations of 31 children from 7 to 16 years of age who underwent cranial expansion surgery during infancy. Thirteen children had mixed syndromic craniosynostosis and 18 children had non-syndromic craniosynostosis.

The researchers found that the children's mean general intelligence quotient of 95.6 was in the average range. Children with syndromic craniosynostosis had a mean intelligence quotient of 83.1, far lower than the 104.7 intelligence quotient of children with non-syndromic craniosynostosis.

Seventy-seven percent of the children who had syndromic craniosynostosis demonstrated normal intelligence, while the children who had non-syndromic craniosynostosis did not exhibit any obvious intellectual disabilities, the researchers report.

"Findings are contrary to the historical impression that has regarded syndromic craniosynostosis as synonymous with intellectual disability," the authors write. "Children with non-syndromic craniosynostosis are of normal intelligence during their school-age years."
