A study of supraorbital notches and foramina in Gujarati human skulls.

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.
