title: Frontosphenoid synostosis: an unusual cause of anterior plagiocephaly.
abstract: Nonpositional anterior plagiocephaly results commonly from unilateral coronal craniosynostosis. We present 2 patients of a rare cause of anterior plagiocephaly known as frontosphenoid synostosis. This condition is characterized by the absence of a harlequin eye (or the harlequin sign on computed tomography), which is usually present in unilateral coronal synostosis. We also observed no reduction in the ear-eye distance, which can distinguish it from coronal craniosynostosis.
