More commonly, however, transcutaneous approaches to the foramen ovale are performed. Although complications with this latter technique are uncommon, studies of the distances to the surrounding extracranial vascular structures are lacking in the literature. The present study aimed to elucidate such anatomical relationships.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>Twenty adult cadavers (40 sides) underwent dissection of the region surrounding the foramen ovale at the external skull base.

Distances tended to be shorter in females, but this did not reach statistical significance.
