Abstract

Aims and Objectives: The main aim of the current study is to evaluate various shapes of FS and differences in its number, size, and position related to the spine of sphenoid bone.


Materials and Methods: 46 adult macerated dried skulls were used in this study. All measurements were made with a digital Vernier calipers and a screw-adjusted compass. Using the formula “A = (x L x B) /4)” = 3.14, L = length, B = breadth of FS, the area was measured. For each measurement, the mean (SD) was determined. The data was analyzed, using SPSS version 20 and a P value of 0.05 was taken as statistically significant. The mean difference in foramen spinosum length (L) and breadth (B), between both sides was measured using an independent t-test.


Results: On the right side, mean antero-posterior (AP) diameter of FS was 3.52 ± 1.33 mm, on left it was 3.26 ± 1.26 mm. the mean TD of the right FS was 3.3 ± 1.19 mm, whereas on the left it was 2.96 ± 1.90 mm. No significant difference was observed, through independent t-test between the AP and TD Diameters on both sides of skull.


Conclusions: Various shapes of foramen spinosum were noted. In comparison to data from earlier research, the foramen spinosum mean diameter was larger. Therefore, for clinicians who work on the middle cranial fossa for various surgeries, it is essential to recognize different variations of the FS
