Dolichocephaly without sagittal craniosynostosis

摘要

Premature closure of the sagittal suture is thought to be fundamental to the etiopathology for the disease process called sagittal craniosynostosis. This process traditionally results in a well-known skull malformation termed dolichocephaly. Over recent decades, some authors have questioned the suture as the primary driving force for this pathology. This is a retrospective cases series of 4 patients from 2011 to 2012 who presented to the Yale Craniofacial Clinic for evaluation of dolichocephaly. The 4 children, 3 boys and 1 girl, had physical examinations and cranial indices concerning for sagittal craniosynostosis; however, subsequent computed tomographic imaging revealed sagittal suture patency. This series adds to a growing body of literature, which describes abnormal head shapes not attributable to overt suture pathology.
