CASE REPORT Pan-Suture Synostosis After Posterior Vault Distraction.

OBJECTIVE

Posterior vault remodeling by distraction osteogenesis is a relatively new technique used for initial correction of turribrachycephaly in children with bicoronal craniosynostosis. We present a new potential complication from this procedure; a case of pan-suture synostosis subsequent to posterior vault distraction.

METHODS

We report an infant girl who presented with bicoronal synostosis in the setting of Saethre-Chotzen syndrome. She underwent posterior vault distraction and was distracted a total of 34 millimeters, with successful osteogenesis at the site.

RESULTS

One year postoperatively, the patient was found to have incidental, asymptomatic pan-suture synostosis on computed tomography.

CONCLUSIONS

To our knowledge, this is the first reported case of delayed craniosynostosis after posterior vault distraction in the literature. The possible pathogenesis and significance of this case are discussed with a review of the current literature.
