Abstract:

Aim: The aim of the study was to determine whether there were variability in the skull base according to magnetic resonance images in migraine patients. Material and Method: A total of 130 magnetic resonans images, including 65 migraine and 65 control groups were retrospectively in the age range 18-50 years. Modified basal angle (MBA), clivo-axial angle in migraine and control groups were measured by a radiologist in magnetic resonans images. The independent t test was used to compare between the groups. The level of significance was set at p < 0.05. In addition, basilar invagination (according to McGregor and Chamberlain line) was evaluated. Results: The migraine group was 13 male, 52 female (mean age of male 30.38±11.5, mean age of female 32.54±9 years). The control group was 15 males, 50 females (mean age of male 34.4 ±8.6, mean age of female 33.14±9.7 years). In the migraine group; the modified basal angle average was 123.78 ± 6.06° and the clivo-axial angle average was 142.65 ± 8.73°. In the control group; the modified basal angle average was 121.6 ± 5.5° and the clivo-axial angle average was 153.66 ± 6.35°. Significant differences were detected between the groups. There was no difference between the genders for both groups. In the migraine group; according to McGregor line in 3 patients and McGregor and Chamberlain line in 2 patients, basilar invagination was observed. Basilar invagination was not detected in the control group.    Conclusion: Changes in the skull base angles (modified basal angle and clivo-axial angle) are observed in migraine patients according to magnetic resonance images.
