Sagittal craniosynostosis: cognitive development, behaviour, and quality of life in unoperated children.

30 patients (23 m/7 f) with untreated, isolated sagittal craniosynostosis (ISC) were re-evaluated at an average age of 9.25 years (2.5 - 25.5). Assessed were neurological status, head shape, school performance, behaviour (with Child Behavior Checklist CBCL), quality of life (TACQOL questionnaire), and a detailed neuropsychological testing (30 patients, 17 siblings as controls). Almost all patients/parents were pleased with the current situation. The aesthetic appearance seemed less obvious compared to photos in infancy. Psychological adjustment as measured by the CBCL was well within normal range. There was a slight tendency for increased internalizing symptoms. TACQOL revealed a lower score for positive emotions. Total score and subscores of test batteries assessing general intellectual performance were in the average range. 6 patients had below average scores in subtests for learning and memory. 12 children had below average scores in one or more subtests for attention. These "deficits" were obviously not of functional importance as all children attended regular school classes (1 exception, an immigrant child of low socio-economic status). These reassuring results regarding school performances, behaviour, and quality of life as well as aesthetic outcome may be helpful when discussing the indication for surgical correction of ISC.
