Abstract

Contour abnormalities presenting after fronto-orbital advancement for craniosynostosis are common. Often there is bilateral temporal depression, the result of leaving a coronal bony gap posterior to the advanced segments. The authors present techniques to prevent this temporal depression by utilizing full-thickness bone grafts for structural support in the inferior coronal defects, and cortico-cancellous graft in the remaining superior coronal and parietal donor defects. Prior to contouring and repositioning the frontal elements, a hand-driven Hudson brace and D'Ericco bit is used to harvest cortico-cancellous bone "mush" from the endo- and ectocortical surfaces. The bandeau and frontal elements are advanced and secured, and the resultant coronal gap is measured. Full-thickness cranial bone grafts are harvested from the parietal regions (near the vertex) and secured in the coronal defect behind the frontal elements. The temporalis muscle is rotated, advanced, and secured to the bandeau. Bone mush is used to fill the remaining superior coronal and donor site defects. Representative case examples are presented.
