Abstract/Artist Statement
Skeletal remains provide a variety of information about a species population and the sub populations within that species. The infraorbital foramen has previously been used to understand dietary niches, paleoecology, the nervous system, and the effect of the nervous system on other bone functions in the facial region in humans and other mammals. The infraorbital foramen is also used in medicine, and the precise location of the infraorbital foramen has been studied to aid and guide maxillo-facial procedures and surgeries. The variation of the infraorbital foramen and its surrounding landmarks has been vital in the use of the anesthesia in such procedures. However, North American populations have never been analyzed. In this project, the hypothesis sought to identify variation in the placement and location of the infraorbital foramen in relation to other facial landmarks between modern North American human populations in three ancestral categories: Native American, White, and Black. The variation in the infraorbital foramen were also analyzed in regards to sex. This project took note of previous researchers and developed new identification of eighteen maxillo-facial landmarks in relation to the infraorbital foramen to ascertain an explicit location of the infraorbital foramen in 199 modern human individuals. The study identified slight variation in the distance of the infraorbital foramen and the apex of the nasal aperture between males and females, that is not statistically determinative.
