Progressive cranial suture stenosis in craniosynostosis.

Despite the growing literature on various types of single suture craniosynostosis, very little information is available on the progression of the synostotic process. This article reports on a group of patients who presented with fusion of a single suture that progressed over the years to involve multiple sutures. Other patients who presented with delayed holocalvarial synostosis are also discussed. Surgery (multiple craniectomies or morcellation procedure) resulted in symptomatic relief in all patients. The diagnostic and therapeutic implications of these types of craniosynostosis are discussed.
