The capacity for cranial remodelling is known to be better at younger ages. The timing of cranioplasty could affect the axis of the skull base. We investigated whether age at the time of distraction is related to the outcome of endocranial morphology correction. In this retrospective study, we investigated the surgical outcome of 14 patients with unilateral craniosynostotic plagiocephaly who underwent one-piece fronto-orbital advancement without bandeau by using a distraction technique between April 2005 and December 2015. Satisfactory results were achieved in all 14 patients with unilateral coronal suture craniosynostosis. An average distraction of 27.3 mm was obtained without detachment from the dura mater. The endocranial angulation of the anteroposterior axis was reduced from 165.4° to 173.5° on average, and the average total change was 8.1°. Between patients aged <1 year and those >1 year, there was a statistically significant difference in the postoperative endocranial angulation of the anteroposterior axis after 3 months (p = 0.003). The distraction techniques resulted in better correction of endocranial morphology. This indicates that the changes in the skull base axis after one-piece fronto-orbital advancement without bandeau are related to the remodelling capacity of the skull base in growing children based on the dura mater.
