2004年12月1日 · Sagittal synostosis is the most common of the primary synostoses, accounting for 50 to 58% of cases, followed by coronal (20 to 29%), metopic (4 to 10%), and lambdoid (2 to 4%). Unlike the syndromic synostoses, simple craniosynostosis seldom results from a …

2015年6月30日 · Boys with single-suture craniosynostosis score lower on academic and IQ tests than girls; and males are more likely than females to have learning problems (50 vs 30%); males with unicoronal synostosis have a 86% risk of learning disorder .

2023年3月6日 · Relative to sagittal synostosis, metopic synostosis was associated with lower IQ scores, while unicoronal synostosis was associated with worse visual perception despite controlling for age at surgery and demographic variables.

Compared to patients with sagittal synostosis, patients with metopic synostosis exhibited lower scores in verbal IQ, full-scale IQ, visuomotor integration, visual perception, and motor control after surgical correction. Despite surgical correction for premature metopic suture fusion, the effect on t …

The IQ in children of primary school age with non-syndromic craniosynostosis is probably slightly lower than or comparable to the IQ of children without craniosynostosis. The verbal IQ, which relates to vocabulary, language sense, and reasoning ability is often lower than the performance IQ, which relates to practical insight, problem-solving ...

2024年6月21日 · However, a 2019 study by Kljajić et al. found that 24 patients with surgically corrected metopic synostosis exhibited an average Full-Scale Intelligence Quotient and normal intellectual ability at school age [24].

2022年2月22日 · Children with isolated single-suture subtypes of craniosynostosis such as sagittal, metopic, and unicoronal craniosynostosis can have distinct neurocognitive profiles. In this review, we discuss the unique neurodevelopmental profiles of children with single-suture subtypes of craniosynostosis.

Craniosynostosis is a primarily morphological problem and has been known as a possible disorder that can result in functional disability. However, a consistent association between neurodevelopmental status, optimal age for surgery, and intracranial pressure (ICP) has not been observed in isolated single suture craniosynostosis (SSC).

In an intelligence quotient (IQ) assessment study, children with syndromic craniosynostosis show significantly lower intelligence (mean full scale IQ, 83.1) than normative population averages (mean IQ, 100) 12).

A decreased IQ may also be part of the problems. [10] It has been suggested that these problems are caused by a primary malformation of the brain, rather than being a consequence of the growth restriction of the skull and elevated intracranial pressure. ... Metopic synostosis is a factor in 5% to 15% of cases, and lambdoid synostosis is seen in ...
