Abstract

SummaryBackgroundAlthough cranial distraction osteogenesis (CDO) is beneficial, few studies have reported on detailed operative procedures and postoperative cranial growth. Herein, we demonstrated the objective effectiveness of CDO in younger infants.MethodsThe study included infants who underwent primary cranial distraction for craniosynostosis. Infants who had hydrocephalus were excluded and those who underwent additional osteotomy surgeries were analysed before the subsequent procedures. The infants' computed tomography data were analysed using Mimics® software (Materialise, Leuven, Belgium) to calculate the cranial volumes and compare them with the Abbott curve for a normal population. We defined cranial growth gap as the difference between the subject data and normal infant data to demonstrate the perioperative effects on cranial growth.ResultsCDO was performed in 10 infants. The mean infant age at the time of surgery was 6.4 months (range, 24–61 months) and the mean duration of postoperative follow-up was 38.9 months (range, 24–61 months). Five infants with Crouzon syndrome and five with Apert's syndrome were included. All infants showed postoperative cranial growth, but cranial growth gap showed postoperative declines for a certain period, indicating cranial growth suppression immediately following expansion. At the last follow-up, all cases were within ±2 standard deviation (SD) compared with the normal population. We derived a formula to predict the CDO target volume using the declining cranial growth gap curve.ConclusionsCDO was applicable and suitable for younger infants requiring aggressive cranial expansion.
