Description
Summary:	Acoustic rhinometry (AR) was performed to standardize the measurement techniques, result interpretation and reference values of nasal cavity volume (NV) in preschool children. (1) Nasal cavity models were used to test the correlations between NV, minimal cross-sectional area (MCA), and nasal resistance. (2) There were 97 four-year-old and 137 five-year-old children underwent AR test. (1) Model tests showed that resist the nce were better correlated with the change of volume than the MCA. (2) The average bilateral NV in preschool children was (2.03 +/- 0.4) ml. No significant gender and age difference were observed (P>0.05). Volume measurement appears more sensitive and reliable than the MCA in assessing nasal patency. The AR result interpretation and normative NV values in preschool children are introduced.
