A previous study conducted on computed tomography scans obtained from healthy children allowed us to conclude that the whole ONFB shape could be accurately described just by the distance measured between the fronto-zygomatic sutures (FZD), independently of age and gender. Our customizable template relies on this measurement.
A re-usable template, built around three supports adjustable to a wide range of FZD, was designed using the CAD 3D Rhinoceros® software and machined in stainless steel 316L. The prototype was used for three children with good preliminary results.
The use of a customizable surgical template allows the surgeon to perform accurate and ideal perioperative remodeling of the ONFB in children suffering from craniosynostosis affecting the forehead sutures. Our prototype is currently the only one to be adjustable according to the FZD. The utility of this device will be assessed in a future prospective clinical study.
