Conclusion: “Although it is an invaluable diagnostic technique, imaging is not employed for assessment of nasal patency, but both rhinomanometry and acoustic rhinometry are widely used for this purpose. The latter two techniques are sensitive and objective, and they provide complementary information on patency of the nasal airway.”
“Rhinomanometry is more invasive and less expeditious than acoustic rhinometry, and the latter technique is of particular value in assessment of rapidly changing mucovascular conditions as in nasal challenge experiments. Mucosal volume change also is accurately measured acoustically and precise anatomical information that is generated graphically is helpful to the nasal surgeon.”
“It is noted in closing that objective assessment of the nasal airways can be minimally invasive and can produce results that are as accurate as other acceptable clinical laboratory tests when adequate equipment and proficient operators are employed.”
