Abstract
OBJECTIVE: To discuss possible reasons for the synostosis of a coronal suture that was transplanted onto synostosis inducing dura in a scaphocephalic human cranium. DESIGN: Case report. SETTING: Supraregional teaching hospital, center for craniofacial anomalies. PATIENT: A bathmocephalic boy, followed from age 7(1/2) to 26 months. INTERVENTION: Radical synostosectomy, radial osteotomies in the parietal bone with outward fracturing of the barrel staves, and left-sided coronal suture transplantation onto the midline was undertaken at the age of 11 months. METHODS: Computer tomography and clinical follow-up. RESULTS: The sutural graft, initially deprived from tensile stress and quickly exposed to the anomalous dura, turned synostotic in one year. CONCLUSIONS: Both cell signaling and biomechanical theories on calvarial morphogenesis, sutural development, and synostosis can apply. An animal experiment is recommended to test which hypothesis prevails.
