Unlocking the Vault: A Historical Review of Craniosynostosis Treatment

Craniosynostosis, the premature fusion of one or more cranial sutures, has challenged clinicians for centuries. This review traces the evolution of its understanding, diagnosis, and treatment from antiquity to the present. Although evidence of the condition spans more than 530,000 years, a mechanistic understanding began only in the 19th century. Virchow's observations on suture fusion and compensatory growth became the foundational principle guiding craniosynostosis treatment. Categorization of syndromic conditions and identification of specific genetic mutations soon followed. Simultaneously, diagnosis advanced from physical examination alone to plain radiographs, three-dimensional computed tomography, ultrasound, prenatal imaging, and molecular testing. Surgical management evolved from the high-mortality strip craniectomies of the 1880s through open cranial vault remodeling, minimally invasive endoscopic and spring-assisted techniques, and distraction osteogenesis. Today, care centers on the multidisciplinary craniofacial team that defines modern craniosynostosis management.
