ABSTRACT: In order to study the site of nasal parameters, nasal minimal cross-sectional area (NMCA), nasal cavity volume (NCV), nasal resistance (NR) and the relations among them.
276 younger adult of normal Cantonese were tested by ECCOVISION acoustic rhinometer.
The results were as follows: 72.95% NMCA in subjects are positioned at internal nostril. The distance from the position of NMCA to the nostril is 1.36 +/- 0.53 cm in male, and 1.06 +/- 0.46 cm in female. There was no difference in NMCA, NCV and NR between male and female. There was significant relationship between the NR and NMCA. There was relationship between the NR and NCV, and there was little relationship between the NR and DCAN.
Acoustic rhinometry is a new objective rhinometric method, but different race must have its standard respectively.
