Gender and ethnic differences of the radiographic image of the frontal region

Harris A.M.P. ; Wood R.E. ; Nortje C.J. ; Thomas C.J. (1987)


Standardized radiographs of 60 adult black patients (30 female, 30 male) were compared with an identical number of patients from the Cape Coloured ethnic group. Features examined included sinus height, sinus width, perimeter, number of edge loculations, inter-orbital distance and sinus area. Measurements were compared between races and sexes using Student's t-tests. Male frontal sinuses were significantly greater in both supero-inferior and mediolateral dimensions and possessed a significant greater number of edge loculations (p < 0,05). Inter-orbital distance was greater in the black racial group when compared with Cape Coloureds (p < 0,05) and sinuses were absent in 6,7% of blacks and only 1,7% of Cape Coloureds. The differences between racial groups and sexes were insufficient for definitive identification purposes.
