Conclusion: “The modified AR device (a narrow diameter wave tube) can be used to generate acceptably accurate area-distance functions of the infant nasal cavity.”
“The modified AR device is best suited to analysis of nasal valve area and demonstrates progressively greater errors in more distal area estimations.”
“The modified AR device can generate acceptably accurate volume measurements of the infant nasal cavity.”
“The accuracy of the modified AR device in distal area determinations is likely adequate to evaluate choanal patency versus occlusion and the device may have utility in screening for choanal atresia in infants.”
“The modified AR device accurately assessed distance to the choana, and can likely be used to measure palate length in infants.”
