The faith of a coronal suture grafted onto midline synostosis inducing dura and deprived from tensile stress.
OBJECTIVE
To discuss possible reasons for the synostosis of a coronal suture that was transplanted onto synostosis inducing dura in a scaphocephalic human cranium.


METHODS
Case report.


METHODS
Supraregional teaching hospital, center for craniofacial anomalies.


METHODS
A bathmocephalic boy, followed from age 7(1/2) to 26 months.


METHODS
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.
