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 7½ 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.
