Clinical trials: Chiari Malformations
Malformation Brain
Neuroradiology Assesses Chiari Malformation's Impact on Airways, Cranial Base, and Sleep Disorders in Children.
The severity of sleep disorders in patients with Chiari malformations can vary. The investigators propose to establish a correlation between the severity of sleep-disordered breathing (SDB) and the quantitative neuroradiological…

Chiari Malformation, Type 1
Identification of Genetic Mutations Involved in Chiari Type I Malformations
Although most cases of Chiari malformation type I (CM1) are sporadic, familial cases of CM1, with or without syringomyelia, suggest a genetic cause in the pathogenesis of these malformations.
