ABSTRACT
The anatomy of the supraorbital notches and foramina has been studied in 249 human skulls. Of 233 skulls, 35.62% had bilateral supraorbital notches, 21.45% had bilateral supraorbital foramina and 16.73% had a notch on one side and a foramen on other side. In present study, total 13 types of combinations were found. The average distance from the nasion to the supraorbital notch/ foramen was 24.30 mm( 16.74-31.86) on right side and 23.73 mm (15.78-31.86) on left side. The exit point can be significantly cephaled to the orbital rim. Knowledge of the anatomy of the region is important for those doing forehead and brow lift surgeries in order to avoid injuring the neuro-vascular bundle passing through these notches/foramina.
ABSTRACT
1500 metacarpals, 300 each of 1st, 2nd, 3rd, 4th and 5th metacarpals of unknown age and sex and 200 metacarpals from 20 articulated skeletons for bilateral study where examined for the length of the bone, number, position, direction and distances from both the ends of nutrient foramina. It was observed that almost all the metacarpals has one nutrient foramen in the middle third of their shaft except in 1st metacarpal in which it was in distal third. It was observed that frequency of number of nutrient foramina differ in different metacarpals. In 1st and 2nd metacarpals foramina were situated mostly on the medial surface and in other metacarpals mostly on the lateral surface. There was a good deal of bilateral symmetry and invariably all foramina were directed away from the growing ends of the bone.
