- Abstract
Purpose: The aim of this study is to compare the length of synostosis and segmented intracranial volume (SIV) with age in children with non-syndromic sagittal synostosis.Methods: Thirty-three consecutive patients (22 boys) who had been operated by cranial vault remodeling because of sagittal synostosis were compared retrospectively from 3D-CT imaging data sets obtained from volumetric CT. The mean age of the patients at preoperative CT imaging was 0.49 (range 0.13–1.3) years and at 1-year postoperative imaging 1.8 (range 1.3–3) years. The mean interval between preoperative CT imaging and surgery was 0.25 (range 0–0.8) years. Pearson’s correlation and Student’s <italic>t</italic> test were used in the statistical analyses.Results: Length of sagittal synostosis correlated positively with age at preoperative CT (<italic>r</italic> = 0.688, <italic>p</italic> < 0.01). Children with total synostosis (<italic>n</italic> = 9) were significantly older (mean age 0.74 vs. 0.4 years, <italic>p</italic> < 0.01) than those with partial synostosis. Of partial synostoses, 9 were located anteriorly, 3 in the middle, and 12 posteriorly. The mean synostosis ratio (synostosis length/total sagittal suture length × 100) was 83%. Preoperative SIV correlated positively with age at preoperative CT (<italic>r</italic> = 0.788, <italic>p</italic> < 0.01), whereas the 1-year postoperative SIV did not correlate with age at operation. The older the child at the time of the operation, the less the percentage SIV increased.Conclusions: Length of sagittal synostosis and SIV increased with age.
