ABSTRACT: This study aimed to evaluate the treatment outcomes and the efficiency of techniques of fronto-orbital advancement (FOA) and posterior cranial vault expansion (PCVE) using distraction osteogenesis in patients with multiple craniosynostosis. We assessed the treatment results and outcomes of 8 patients with multiple craniosynostosis at the Kagoshima University Hospital between 2005 and 2019. Each 4 patients underwent FOA and PCVE, respectively, using distraction osteogenesis. The cranial volume and developmental quotient (DQ) were measured at the preoperative period and 1 year after surgery. The mean patient age at surgery was 22 months. The mean preoperative cranial volume was 1027 and 1071 cm3 in the FOA and PCVE groups, respectively. The mean preoperative DQ scores were 74 and 67, respectively. After 1-year of follow-up, the corresponding mean cranial volume became 1108 and 1243 cm3, respectively. The corresponding mean DQ scores also improved to 74 and 81, respectively. The postoperative follow-ups in all cases were uneventful, except for persistent epilepsy in 1 patient. Fronto-orbital advancement and PCVE using distraction osteogenesis might contribute to good outcomes in expanding cranial volume, cosmetic osteogenesis, and infantile development in patients with multiple craniosynostosis. Regarding the cranial volume expansion, especially, PCVE using distraction osteogenesis is more effective than FOA.
