Description
Aim: To evaluate the morphometry of foramen ovale and its variations in dry skulls of India. Methodology: This present study was undertaken on 50 dry adult human skulls obtained from Department of Anatomy, Santosh Medical College, Ghaziabad, Uttar Pradesh, India . The foramen ovale was observed from the extra cranial view of skull base. Skulls with damaged walls of foramen ovale were not considered. The shape of the foramen ovale was noted by direct inspection as per the classification. Accessory foramen and bony growth around the margins of foramen were also noted. Measurements of foramen ovale were taken by placing a pair of divider on antero-posterior length and transverse diameters of the foramen and then carefully transferred to a meter rule for the readings to be taken. Variation in right and left side in length and breadth was also evaluated. Results: A total of 38 skulls were studied. We found most common shape of foramen ovale was of oval type and was present in 52% cases. The shape of foramen ovale was round in 18% cases, almond in 24% cases and D-Shaped in 6% cases. Out of 50 skulls, spines were present in 4 skulls (8%). The maximum length and width of foramen ovale on the right and left side was 8.08 mm, 5.14 mm and 9.98 mm, 5.26 mm respectively. Minimum length and width of foramen ovale on right and left side was 6.04 mm, 2.92 mm and 5.62 mm, 2.16 mm respectively. Mean length on right and left side was 7.10 mm and 7.66 mm and mean width on right and left side was 4.02 mm and 3.83 mm respectively. Conclusion: Knowledge in variations of morphometry of foramen ovale has various clinical, anatomical and surgical importance. The results of this study will provide an in-depth knowledge about the foramen ovale in dry skulls to the anatomists. This knowledge will also be useful to clinicians and surgeons in planning and executing procedures of the skull base in Indian population.
Abstract (English)
Aim: To evaluate the morphometry of foramen ovale and its variations in dry skulls of India. Methodology: This present study was undertaken on 50 dry adult human skulls obtained from Department of Anatomy, Santosh Medical College, Ghaziabad, Uttar Pradesh, India . The foramen ovale was observed from the extra cranial view of skull base. Skulls with damaged walls of foramen ovale were not considered. The shape of the foramen ovale was noted by direct inspection as per the classification. Accessory foramen and bony growth around the margins of foramen were also noted. Measurements of foramen ovale were taken by placing a pair of divider on antero-posterior length and transverse diameters of the foramen and then carefully transferred to a meter rule for the readings to be taken. Variation in right and left side in length and breadth was also evaluated. Results: A total of 38 skulls were studied. We found most common shape of foramen ovale was of oval type and was present in 52% cases. The shape of foramen ovale was round in 18% cases, almond in 24% cases and D-Shaped in 6% cases. Out of 50 skulls, spines were present in 4 skulls (8%). The maximum length and width of foramen ovale on the right and left side was 8.08 mm, 5.14 mm and 9.98 mm, 5.26 mm respectively. Minimum length and width of foramen ovale on right and left side was 6.04 mm, 2.92 mm and 5.62 mm, 2.16 mm respectively. Mean length on right and left side was 7.10 mm and 7.66 mm and mean width on right and left side was 4.02 mm and 3.83 mm respectively. Conclusion: Knowledge in variations of morphometry of foramen ovale has various clinical, anatomical and surgical importance. The results of this study will provide an in-depth knowledge about the foramen ovale in dry skulls to the anatomists. This knowledge will also be useful to clinicians and surgeons in planning and executing procedures of the skull base in Indian population.
