Key Points
- Computational modeling was used to investigate race and gender
differences on normal nasal physiology.
- Our findings suggest that East Asians had the largest median nasal
volume, while Caucasians had the smallest median nasal volume.
However, Blacks demonstrated the largest variability in the
distribution of nasal cavity volume.
- As expected, males had a larger distribution of nasal cavity volume
than females. Furthermore, Caucasian females had the smallest average
nasal volume, whereas Black males had the largest average nasal
volume.
- Blacks had the largest median nasal index and Caucasians had the
smallest median nasal index. In terms of gender differences, males had
a slightly larger median nasal index than females.
- Median nasal resistance was lowest for East Asians and highest among
Caucasians; however, nasal resistance between both genders was not
significantly different.
