[Study of rhinophysiology on Black people from Africa].

ABSTRACT

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 (male29, female 17) from Africa were tested by ECCOVISION acoustic rhinometry and 50 Chinese (male25, female25) 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.
