Abstract

Background: The piriform aperture (PA) is the skeletal aperture located in the middle part of the face. There are many variations in morphometric measurements of nasal bones, piriform apertures and their shapes in different population.
Objective of present study was to study morphological and morphometric features of nasal bone and piriform aperture.
Material and Methods: Adult human skulls available from collection of dried skulls were used for study purpose. Skull bones of unknown age and sex were obtained. Height, width of nasal bone, height, upper and lower width of piriform aperture, shapes of nasal bone and piriform aperture were observed.
Result: Height, upper width and lower width of piriform aperture were greater in male as compared to female. This difference was not statistically significant for upper width of piriform aperture (p=0.49) and for lower width of piriform aperture (p= 0.65) while the difference in height of piriform aperture was statistically significant. (p <0> Conclusion: Majority finding of the present study are in concordance with Indian population studies while significant differences have been noted in comparison to the morphometric measurements of Turkish, Korean, Brazilian and Anatolian population. These variations might be because of differences in ethnicity.
