Statistical analysis of changes of pediatric nasal patency with growth

Abstract

The purpose of this study was to further investigate the changes of pediatric nasal patency with growth. The nasal patency of Japanese children aged 6 to 14 years was measured by active anterior mask rhinomanometry in terms of effective cross-sectional area (ECSA). The total nasal ECSA of the boys studied was larger than that of the girls of the same age groups. Total nasal ECSA was significantly correlated to age and height, as not transformed, and to weight as logarithmically transformed. Moreover, our study suggests that pediatric nasal resistance is inversely proportional to the second power of age, of height, and of body weight; however, it was concluded that the parameter of height was in itself sufficient to permit an approximate calculation of the total nasal ECSA in normal subjects.
