Welcome to HCM
First of all I would like to inform you that craniosynostosis
is a congenital defect of skull where one or more suture(between two bones)are closed earlier than normal.So normal growth of brain along with skull size is hampered.
Treatment is needed (mostly surgical) in infancy age.The prematured closed bony joint is surgically separated so that they can grow normally.Usually no permanent plate or fixer is needed in this case.
So do not worry about any metal palate
as your report also revels nothing.
