The timing of surgery for craniosynostosis depends on the condition of the craniosynostosis; no special treatment is required for those with recessive craniosynostosis; if an infant has a dominant craniosynostosis, although there is no best accepted time for surgery, it is best to be hospitalised 6 to 12 months after birth for surgical treatment, with the aim of removing the bulging sac, returning the contents such as the bulging brain tissue and repairing the fissure as early as possible; if that time frame is missed, surgery is still possible and a prompt visit to a doctor is required for planning.
