| Abstract: | OBJECTIVE: The aim of this study was to measure nasal cavity volume (NV) in preschool children with the use of acoustic rhinometry (AR). STUDY DESIGN AND SETTING: Prospective study: 1) Nasal cavity models were used to test the correlations between NV, minimal cross-sectional area (MCA), and nasal resistance; 2) 97 four-year-olds (48 boys, 49 girls) and 137 five-year-olds (68 boys, 69 girls) children were selected to undergo AR. RESULTS: 1. Model tests showed that the resistance correlated better with the changes of the volume than the MCA. 2. The average bilateral NV in preschool children was 2.03 +/- 0.4 mL. There was no significant difference in either gender (P = 0.2) or age (P = 0.197). CONCLUSIONS: Volume measurement appears more sensitive and reliable than the MCA in assessing nasal patency. AR was easily performed on preschool children, and normative NV values were achieved. SIGNIFICANCE: The results and conclusions can be used to establish a standardized technique for AR measurement and interpretation. |
