| Abstract: | Objectives Chiari type II malformation (CII) is a congenital deformity of the hindbrain. The posterior fossa and cerebellum are small
in CII. The cerebellar atrophy is associated with cognitive and motor deficits. Brainstem compression occurs in some patients
with CII for whom posterior fossa decompression may be life saving. The aim was to determine whether posterior fossa decompression
can prevent or reduce the cerebellar atrophy in CII. |
