Conclusion: “Acoustic rhinometry is an appropriate method for detecting and recording the nasal cycle in normal subjects in terms of the cross- sectional areas and volume of the nasal cavity.”

“When AR is used to evaluate volume changes in the nasal cavity by means of the template tool and technique, it can provide accurate measurements and assess nasal volume changes accordingly. For repeated nasal volume measurements by AR over a prolonged period, use of a template can reduce operator- dependent error in CSA2 measurements to zero and operator- dependent error in volume measurements to 11%.”
