MORPHOMETRIC ANALYSIS OF FORAMENS AT SKULL BASE IN ADULT VIETNAMESE DRY SKULLS
Main Article Content
Abstract
The frequency, location, shape and size of the foramens at skull base were analyzed by describing the cross section of 30 adult Vietnamese dry skulls. The results show that the average size of the optic canal is 3.69×4.36 mm, most of which are oval. The average size of the foramen rotundum is 2.69×2.67 mm, and there are 1.7% accessory foramen. The foramen ovale with an average size of 6.29×3.62 mm are all oval. The average size of foramen spinosum is 2.47 × 2.10mm, with 1.7% accessory foramen. The average size of jugular foramen is 11.9×5.72 mm and showed a complete septum in 11.7% cases. The average size of the internal acoustic meatus is 4.04×4.46 mm. The average size of the hypoglossal canal is 4.71×3.51 mm. The average size of the foramen magnum is 34.28×29.28 mm. The foramen vesalius were found in 13.3% of the right side and 30% of the left side, with an average size of 1.17×0.99 mm. The average size of mastoid foramen is 1.95×1.85 mm, with 76.7% on the right and 86.7% on the left. Understanding the morphological characteristics of skull base foramen is of great significance in anatomy and volume calculation, and it is helpful for clinicians to identify the foramen to avoid damaging the components passing through the foramen under the intervention of skull base area.
