Abstract
✓ Premature closure of the sagittal suture is the most common form of craniosynostosis, but this condition occasionally goes unrecognized until the child is too old to undergo procedures that depend upon continued calvarial growth for success. As the entire calvaria is affected and thus misshapen by sagittal synostosis, late correction involves total calvarial reconstruction. The extensive nature of this undertaking has precluded its utilization despite the presence of significant deformities. Adapting the techniques and experience gained from craniofacial surgery, the authors performed total calvarial reconstruction on nine children with sagittal synostosis and subsequent scaphocephaly diagnosed after the age of 1 year. In each case the goals of shortening the anteroposterior length, widening the biparietal diameter, and reducing frontal and occipital deformities were met. Morbidity consisted of acute blood loss, postoperative hyponatremia, and in one case a residual skull defect. The rationale for this procedure and the techniques utilized are discussed.
