Introduction: The position of the tonsillar tip in relation to the foramen magnum varies from individual to individual, even after excluding all predisposing factors that might alter the tonsillar tip position; the mere presence of the tonsillar ectopia should not be misinterpreted as Chiari malformation. Aim: Our aim is to establish the normal range of the tonsillar tip position and the incidence of tonsillar ectopia and its relation to age and sex in asymptomatic Indian children with structurally normal MRI brain imaging. Materials and Methods: We have conducted a retrospective data collection comprising 301 structurally normal MRI brain images done for children younger than 14 years, in which we measured the level of the tonsillar tip from the foramen magnum by taking the Mc Rae line as constant. Measurements were taken in the right and left parasagittal sections of T1-weighted MRI brain images by using pre-existing software. Statistical Analysis Used: Data analysis was done by SPSS v 25.0; all P values <0.05 were considered statistically significant. Results and Conclusion: The incidence of tonsillar ectopia in Indian children was about 13.79%, and the median tonsillar position was 3.2 mm above the foramen magnum with a median range of 5.2 mm above to the level of the foramen magnum (0).
