Non-metrical morphologic variations of skull foramina were studied with 250 crania of Korean adults. Studied morphologic variationts were presence of supra-orbital foramen(33.3%), frontal foramen(27.7%), accessory infraorbital foramen(13.2%), accessory lesser palatine foramen(41.0%), Vesalius foramen (16.9%), Huschke foramen(18.8%), condylar canal(62.6%) and parietal foramen(49.8%). The ahsence of posterior ethmoidal foramen(0.2%), zygomaticofacial foramen(7.1%) and mastoid foramen(30.2%) was also observed. The variations were presence of the exsutural location of anterior ethmoidal foramen 30.8%), mastoid foramen(35.9%) and incomplete development of oval foramen(4.9%), foramen spinosum(9.6%), hypoglossal foramen(9.6%). And incidence of these variations were compared with 12 different geographical localitics.
