The role of rhinomanometry, acoustic rhinometry, and mucociliary transport time in the assessment of nasal patency

We conducted a study of 60 patients with different nasal pathologies who complained of nasal obstruction. Our goal was to evaluate the reliability of rhinomanometry, acoustic rhinometry, and the measurement of mucociliary transport time in helping make the diagnosis of nasal pathologies. We also sought to discover whether there is a correlation between the findings of these objective tests and the results of patients' own subjective assessments of nasal obstruction. We found that acoustic rhinometry was more specific and more sensitive than rhinomanometry in diagnosing rhinopathies in patients with structural anomalies. Symptom scores as rated by patients on the visual analog scale frequently did not correlate with objective measures, as patients often overestimated the severity of their obstruction. However, for a few patients, there was a correlation between symptom scores and mucociliary transport times.
