[Study of rhinophysiology on Black people from Africa].
OBJECTIVE
To study the difference of nasal resistance (NR) and nasal parameters between Chinese and Black people from African.


METHODS
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.


RESULTS
NMCA of both Chinese and Black people were positioned at internal nostril. There was significant relationship between the NR and NCV, NR and NMCA.


CONCLUSIONS
The NR is decided by NMCA and NCV. In the same condition, there are different nasal parameters among different race.
