Clinical or rhinometric assessment of the nasal airway--which is better?

Multiple regression analysis was used to examine the relationship between clinical and rhinometric assessment of the nasal airway and the subjective nasal airway. Clinical examination and rhinometry correlated poorly with the subjective overall nasal airway. Analysis of the data obtained on the differences between the right and the left nasal cavities showed that adding rhinometry did not improve on clinical examination in predicting the patient's subjective sensation of nasal airway.
