Cranial compression using distractors in reverse fashion as an alternative method for correcting scaphocephaly in older patients.

BACKGROUND

Intraoperative calvarial contraction of conventional calvarial remodeling is more difficult in scaphocephaly patients who are 1 year or older in age. In our current study, gradual cranial compression with a distractor was used to correct scaphocephaly in this older age group and the surgical results were quantitatively analyzed.

METHODS

Gradual cranial compression was used to treat 7 sagittal craniosynostosis patients. The mean age was 20.9 months (range, 12-32 months) and the mean follow-up period was 65 months (range, 3-81 months). Computed tomography was used to calculate the cephalic index (CI; equal to the maximum width of the head/maximum length of the head ×100), and the ratios of these indices at 3 different time periods (before, immediately after, and at 1 year postoperatively) were evaluated.

RESULTS

An average cranial compression of 18 mm was found to be possible with an average CI increase from 67.9 to 73.5. The CI ratio at 1 year after surgery was found to be the highest, showing a 9.8% increase.

CONCLUSION

Sagittal craniosynostosis patients are less easy to treat with conventional calvarial remodeling surgery if they are older than 1 year. Gradual cranial vault compression with distractors can be another option in these cases.
