BACKGROUND: The aim of the current study was to determine the intracranial volume (ICV) and cephalic index (CI) in patients operated for sagittal synostosis, and to compare the outcome of 2 different surgical techniques: craniotomy combined with springs and modified pi-plasty. METHODS: The authors studied all patients who had been operated for isolated sagittal synostosis and registered in the Gothenburg Craniofacial Registry until the end of 2012 and who had undergone a preoperative and/or postoperative (at 3 years of age) computed tomography examination. Sex- and age-matched controls were identified from children who had undergone computed tomography for other reasons. RESULTS: Craniotomy combined with springs increased the ICV and CI from 802 ± 127 mL (mean ± SD) and 70.1 ± 4.0 to 1300 ± 158 mL and 73.1 ± 3.3, respectively. The corresponding values for controls were 796 ± 136 mL and 83.6 ± 7.3 preoperatively and 1334 ± 136 mL and 80.0 ± 4.5 at 3 years of age. Pi-plasty increased the ICV and CI from 1014 ± 115 mL and 69.7 ± 3.3 to 1286 ± 122 mL and 74.1 ± 2.6, respectively. Corresponding values for controls were 1043 ± 153 mL and 83.4 ± 7.0 preoperatively and 1362 ± 122 mL and 79.6 ± 3.9 at 3 years of age. CONCLUSIONS: There was no significant difference between craniotomy combined with springs in children younger than 6 months and pi-plasty in older children regarding the efficacy of improving ICV and CI. Neither of the techniques fully normalized the head shape.
