As opposed to the less pronounced tonsillar herniation seen with Chiari I, there is a larger cerebellar vermian displacement. Neurosurgery, 49 5 Analysis of tracheostomies in a Paediatric Intensive Care Rare post-operative complications include hydrocephalus and brain stem compression by retroflexion of odontoid.
