The Chiari Malformations: A Bibliometric Analysis of the 100 Most Cited Articles
2023, World NeurosurgeryStructural Changes in the Cervicomedullary Junction in Adult Chiari Patients
2022, World NeurosurgeryCitation Excerpt :Although traditionally characterized by the extent of tonsillar descent beyond the foramen magnum, additional measurements have been developed to better characterize the severity of CM1. Detailed linear, angular, and area measurements have been used, beginning with skull X-ray imaging and progressing to magnetic resonance imaging (MRI).10-12 Utilizing X-ray and computed tomography images, Vega et al. found significantly smaller posterior fossa areas in CM1 patients, similar to Badie et al., who measured the ratio of posterior fossa volume to supratentorial volume on MRI.10,12
Posterior Fossa Dimensions of Chiari Malformation Patients Compared with Normal Subjects: Systematic Review and Meta-Analysis
2020, World NeurosurgeryCitation Excerpt :Under the label sagittal dimensions, we grouped measurements similar to Twining's line. Twining's line was defined by Vega et al.5 as extending from the tuberculum sellae to the endinion. Karagöz et al.17 measured Twining's line as a line connecting the tuberculum sellae and internal occipital protuberance.
A morphometric assessment of type I Chiari malformation above the McRae line: A retrospective case-control study in 302 adult female subjects
2018, Journal of NeuroradiologyCitation Excerpt :For example, the retrograde angulation of the odontoid process, a common presentation of CMI, is thought to compromise the PCF [11,13,22,23]. Beyond PCF, occipital and odontoid morphology, other research efforts have explored the relationship of platybasia (flattening of the skull base), clivus underdevelopment, tentorial angulation, oropharynx anomalies, and other PCF and cerebral abnormalities with CMI diagnosis [9–11,13,14,19,24–28]. Given the growing body of evidence supporting the notion of additional structural markers of CMI beyond TP above the McRae line, it is important to acknowledge that the consistency of these morphological effects remains elusive.
