Morphological and ultrastructural investigation of the posterior atlanto-occipital membrane: Comparing children with Chiari malformation type I and controls. The fibrous posterior atlanto-occipital membrane (PAOM) at the craniocervical junction is typically removed during decompression surgery for Chiari malformation type I (CM-I); however, its importance and ultrastructural architecture have

Measurement of CSF flow and brain motion in Chiari malformation type I subjects undergoing posterior fossa decompression surgery. Radiologically, Chiari malformation type I (CM-I) is characterized by cerebellar tonsil herniation of at least 5 mm through the foramen magnum. In symptomatic cases, posterior fossa decompression (PFD) surgery is often performed and improves symptoms in approximately

Chiari Malformation: Diagnosis, Classifications, Natural History, and Conservative Management. WFNS Spine Committee Recommendations. A comprehensive search was conducted in PubMed/EMBASE/MEDLINE databases. Inclusion criteria included publications between January 2011 and December 2022 on CM diagnosis classification, natural history, and conservative management. This study aims to offer an update on diagnosis classifications, natural history, and conservative management in Chiari Malformation (CM). Chiari Malformation type 1 involves cerebellar tonsil herniation leading to neurological symptoms. There is controversy regarding its pathophysiology and optimal management, especially for asymptomatic cases. Previous research has focused on surgical outcomes with limited consensus on conservative

Pediatric Chiari Malformation Management: WFNS Spine Committee Recommendations. A systematic literature review and consensus using Delphi method. This review aims to provide an overview on Chiari malformation in pediatric patients, highlighting the specific clinical manifestations and surgical treatment options. Chiari malformation in children presents a real difficulty to the general neurosurgeon because children are not smaller adults. In the absence of pediatric neurosurgeons, as in many countries of the world, a need for education of general neurosurgeons on the management of Chiari malformation in children was identified. The authors carried out an extensive review of the literature in PubMed database of the last 10 years addressing the topic of Chiari malformation in children

Indications for Surgery and Surgical Options in Chiari Malformation: WFNS Spine Committee Recommendations. A systematic literature review and consensus using Delphi method. This review aims to create recommendations on the surgical indications and approaches to treat Chiari Malformation (CM) with or without syringomyelia. Despite the growing body of knowledge on CM, there are diverse

Predecompression and postdecompression cognitive and affective changes in Chiari malformation type I. The role of the cerebellum in cognitive function and psychiatric symptoms is poorly understood and particularly understudied in patients with cerebellar pathologies such as Chiari malformation type I (CM-I). Additionally, it is unclear if interventions targeted toward the cerebellum might impact

Building consensus regarding the definition of abnormal craniocervical motion in pediatric patients with Chiari malformation: a modified Delphi study. Abnormal craniocervical motion (ACCM) in the setting of pediatric Chiari type 1 and 1.5 malformation (CM-1/1.5) is generally regarded to be uncommon. The focus of this modified Delphi study was to investigate and build consensus regarding

Prevalence of Chiari malformation type 1 is increased in pseudohypoparathyroidism type 1A and associated with aberrant bone development. Albright hereditary osteodystrophy (AHO) is caused by heterozygous inactivating mutations in GNAS. Patients with maternally-inherited mutations develop pseudohypoparathyroidism type 1A (PHP1A) with multi-hormone resistance and aberrant craniofacial and skeletal development among other abnormalities. Chiari malformation type 1 (CM1), a condition in which brain tissue extends into the spinal canal when the skull is too small, has been reported in isolated cases of PHP1A. It has been hypothesized to be associated with growth hormone (GH) deficiency. Given the adverse clinical sequelae that can occur if CM1 goes unrecognized, we investigated the previously

Revisiting the factor structure of the Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2): Evidence for a bifactor model in individuals with Chiari malformation. The Short-Form McGill Pain Questionnaire-2 (SF-MPQ-2; Dworkin et al., 2009) is intended to measure the multidimensional qualities of pain (i.e., continuous, intermittent, neuropathic, and affective) as well as total pain. Using structural equation modeling, we evaluated the fit of four competing measurement models of the SF-MPQ-2-an oblique 4-factor model, a 1-factor model, a higher-order model, and a bifactor model-in 552 adults diagnosed with Chiari malformation, a chronic health condition whose primary symptoms include head and neck pain. Results revealed the strongest support for the bifactor model, suggesting that SF-MPQ-2 item

The utility of poly(somno)graphy in evaluating children with Chiari malformation type II before and after surgical intervention: a case series. Children with Chiari Malformation type II (CM-II) have an increased risk of sleep apnoea. The aim of the study was to describe the management of patients with CM-II in relation to sleep apnoea syndrome, clinical symptoms and magnetic resonance imaging

Successful spinal cord stimulation using fast-acting sub-perception therapy for postoperative neuropathic pain of syringomyelia with Chiari malformation type 1: a case report and literature review. Central neuropathic pain after foramen magnum decompression (FMD) for Chiari malformation type 1 (CM-1) with syringomyelia can be residual and refractory. Here we present a case of refractory central

A comparative analysis of neuroendoscopic foramen magnum decompression versus traditional open surgery for Chiari Malformation Type I. Chiari Malformation Type I (CM1) is characterized by the downward displacement of the cerebellar tonsils below the foramen magnum. The standard surgical treatment for CM1 is foramen magnum decompression and atlas laminectomy (FMD-AL). However, there is a growing

Chiari malformation type I and craniosynostosis in adults: Retrospective analysis over a 10 year period in a tertiary care Centre. Chiari malformation type 1 (CM1) pathophysiology remains uncertain. One theory involves small posterior fossa volumes leading to tonsillar herniation. Craniosynostosis causes suture fusion, which can limit skull growth, and has been investigated in paediatric CM1

Pain-depression relationship, quality of life and acceptance of illness among patients with Chiari malformation type I: A cross-sectional study. Chiari malformation type I (CM-I) is a congenital anomaly of the hindbrain. The most common symptoms include suboccipital tussive headache, dizziness and neck pain. Recently there has been growing interest in the psychological and psychiatric aspects

Effects of Two Exercise Regimes on Patients with Chiari Malformation Type 1: a Randomized Controlled Trial. This study aims to measure the effects of two different exercise programs on neck pain, proprioception, balance, coordination, posture, and quality of life in patients with Chiari malformation (CM) type 1. Sixteen patients were randomized to two different exercise programs: a tailored

The prevalence of Chiari malformation among children with persistent dysphagia. Brain imaging has been utilized as a diagnostic tool in the workup of persistent pediatric dysphagia, yet the indications for imaging and the prevalence of Chiari malformation (CM) have not been established. to evaluate the prevalence of CM anomalies in children who underwent brain magnetic resonance imaging (MRI

Delayed post-operative aggravation of sleep related disturbances in patients of basilar invagination with Chiari malformation: case report and review of the literature. Sleep apnoea is common in patients with Basilar Invagination with Arnorld Chiari Malformation (ACM). Various studies have shown its incidence in the range of 60-70% among such patients. Most of the studies have shown improvement in sleep disturbances after decompressive surgeries for Chiari Malformations. There is no report of postoperative deterioration due to sleep apnoea in these patients. Authors report two cases of basilar invagination associated with ACM and Platybasia, who deteriorated probably due to worsening of pre-existing sleep disorders on 3rd and 7th postoperative days after their surgeries, despite clinico

Foramen magnum decompression for Chiari malformation type I - UK surgical practice. Symptomatic Chiari 1 malformation (CM1) is a common condition in Neurosurgery.
