Foramen ovale is a surgically important aperture of the skull since it allows approach to and manipulation of the
trigeminal ganglion as it lies in the Meckel’s cave. This transfacial approach, Hartel’s approach, requires two anatomical poin
ts for
accurate cannulation; the zygomatic point and the pupil point. This study describes the morphology and location of foramen oval
e and
describes the pupil point in relation to the medial canthus in the Kenyan population. Department of Human Anatomy departmental
review board approved the study. Two hundred dry skulls from the Department of Human Anatomy were studied using a digital calli
per
with help of a measuring frame. The results were analysed using SPSS version 20. The results showed the length and width of rig
ht
foramen ovale was 7.69 mm mean (SD
±
1.31) and 4.24 mm (
±
0.64) respectively while the left foramen ovale was 7.68 mm (
±
1.23) and
4.28 mm (
±
0.74). The distance of the zygomatic point from the external auditory meatus on the right was 23.54 mm (
±
2.26) and the left
was 23.49 mm (
±
2.16). The median distances of the pupil point in relation to the medial canthus was 9.5mm on the right and 8.1 mm on
the left. These results were significantly different from other population data. Neuronavigational aids to foramen ovale in Ken
yans
should take this into consideration
