Born and raised in Tokyo, graduated from Juntendo University and joined the department of neurosurgery at Juntendo University under Professor Kiyoshi Sato after finishing residency.
Was in charge of pediatric neurosurgery mainly in anomalies in Juntendo University hospital from 2010 under the mentorship of professor Hajime Arai and professor Masakazu Miyajima.
From 2021, joined the department of Neurosurgery, International University of Health and Welfare under Prof. Akira Matsuno, a new Medical school located just beside Narita Airport.

Interim Meeting of AASPN/303A
Introduction
frontal orbital advancement (FOA) is a suitable procedure to achieve sufficient increased intracranial volume (ICV) for patients who suffer from craniosynostosis. However there are some disadvantages such as relapsing and if one needs to extend the frontal area to obtain an appropriate ICV, it may affect the aesthetic outcome of the child. We have applied posterior cranial vault distraction osteogenesis(PVDO) with frontal orbital remodeling(FOR) or FOA in craniosynostosis to obtain sufficient ICV in the posterior area and leave the frontal area to solve the aesthetic issues.
Materials and Method
We retrospectively analyzed 9 patients who underwent PVDO with FOA or FOR and cauculated the ICV using using the MimicsR and 3-MaticR (Materialize, Leuven, Belgium) on three-dimensional CT scans.
Results
4 boys and 3 girls were included in this study. PVDO increased the ICV 220mL in average (125%). Two cases underwent FOA and obtained another 73mL(107%) and 138mL (114%) respectively. Seven cases underwent FOR but this was to correct aesthetic issues so the mean increased ICV was 102%
Conclusion
PVDO can provide an acceptable increase of ICV which is performed relatively safely. Additionally, adding FOR can solve the aesthetic issues without considering the increase of ICV.
