Morphometric Analysis of Tentorial Incisura and its Clinical Implications
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 7
Abstract
Introduction: Tentorial incisura is important due to transtentorial herniation, a terminal pathophysiological event in various neurosurgical conditions. With advent of modern neuroradiological methods lacuna in understanding of herniation syndromes is being gradually filled. Aim: To analyze anatomical variation, classy types and their clinical relevance and interpretation on neuroradiological imaging. Materials and Methods: Total 100 magnetic resonance images (MRI) of brain were analyzed using RadiAnt DiCom viewer. Statistical methods used descriptive analysis, Pearson correlation, significant two-tailed test, student t-test, and analysis of variance. Results: Notch length is typed into three, maximum notch width into three. By combination, the tentorial incisura is typed into nine types. Correlation between parameters and statistical significance is interpreted. Conclusion: Morphometry classification and relative smaller dimensions of anatomical structures and relationships in Indian population have been elucidated. Various manifestations of herniation syndromes explained. Pre-operative MRI morphometric analysis has been highlighted.
