Abstract

The Chiari 1 malformation is characterized by > 5-mm herniation of the cerebellar tonsils through the foramen magnum. Consequent compression of the brain stem and nearby neuronal structures involved in respiratory control and maintenance of pharyngeal wall muscle tone may result in respiratory changes during sleep. These changes include respiratory failure and arrest, as well as sleep-related breathing disorders (ie, OSA and central sleep apnea). Although data have accrued on the significance of sleep-related breathing disorders in patients with the Chiari 1 malformation, many management questions remain unanswered. This article reviews the available literature on prevalence and management of sleep-related breathing disorders in patients with the Chiari 1 malformation.
