Abstract

Three hundred and seven normal CT scans of the head were prospectively analysed to assess jugular foramen dominance. After assessment, hand preference was elicited. Of these, 276 were right-handed and 31 were left-handed. Of the right-handed patients: 180 had a larger jugular foramen on the right; 63 had a larger jugular foramen on the left; and in 33 no difference could be discerned. Of the left-handed patients: 11 had a larger jugular foramen on the right; 16 hada larger jugular foramen on the left; and in four no difference couldbe discerned. The results suggested a significant association betweenjugular foramen dominance and hand preference.
