Application of acoustic rhinometry in assessment of preschool children nasal cavity volume / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#Acoustic rhinometry (AR) was performed to standardize the measurement techniques, result interpretation and reference values of nasal cavity volume (NV) in preschool children.@*METHOD@#(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.@*RESULT@#(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).@*CONCLUSION@#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.
