Objective:
To study the difference of nasal resistance (NR) and nasal parameters between Chinese and Black people from African.
Method:
Nasal minimal cross-sectional area (NMCA), nasal cavity volume (NCV), nasal resistance (NR) in 46 adult Black people (male:29, female: 17) from Africa were tested by ECCOVISION acoustic rhinometry and 50 Chinese (male:25, female:25) were used as contrast.
Result:
NMCA of both Chinese and Black people were positioned at internal nostril. There was significant relationship between the NR and NCV, NR and NMCA.
Conclusion:
The NR is decided by NMCA and NCV. In the same condition, there are different nasal parameters among different race.
