title: Atypical post-adenoidectomy Grisel's syndrome in Crouzon child with kyphotic skull base.
abstract: Crouzon syndrome is characterized by abnormal craniofacial growth due to craniosynostosis. Skull base may also be involved in the pattern of malformations. Grisel's syndrome, an inflammation-mediated atlanto-axial instability occurs rarely in children after adenoidectomy. We report a 9-year-old female Crouzon patient, without vertebral anomalies, who developed severe torticollis few days after adenoid curettage. A deformity of the skull base alone might have induced an irregular arrangement of the craniocervical junction elements, thus increasing the susceptibility to cervical spine complications.
