ABSTRACT
RELEVANCE: Objective diagnostics of nasal breathing disorders in children is a vital issue given frequent inconsistency between patients’ subjective feelings and actual nasal patency. Active anterior rhinomanometry (AAR) is an objective procedure and the golden standard for nasal breathing evaluation. But still, there are no actual data in literature on relevant criteria used to evaluate nasal breathing in children.
OBJECTIVE: To determine reference values for indicators evaluated by active anterior rhinomanometry in Caucasian children aged 4-14 based on statistical data.
MATERIAL AND METHODS: Overall, we examined 659 healthy children of both sexes who were divided into 7 groups as per their height. All children included into our research underwent AAR according to the conventional procedure. AAR indicators (Summary Flow left, Summary Flow right, Summary Flow, Summary Resistance left, Summary Resistance right and Summary Resistance Flow) are given as median (Me) and values of 2.5, 25, 75, and 97.5 percentiles.
RESULTS: We determined direct moderate, significant and strong correlations between summary speed of the flow and resistance in both nasal passages and separate speeds of the flow and right and left resistance in inhalation and exhalation (r=0.46-0.98, p<0.001). We also established weak correlations between AAR indicators and age (r= -0.08-0.11), and between ARR indicators and height (r= -0.07-0.15). Reference values for AAR indicators were successfully determined.
CONCLUSIONS: AAR indicators are likely to be determined bearing a child’s height in mind. Determined reference intervals can be applied in clinical practice.
