A quick, non-invasive means to quantify nasal cavity volumes and cross-sectional areas using sound pulse technology.
Reflections of the should pulse, produced by changes in the cross-sectional area of the nose, are processed by the PC to provide a plot of area, as a function of distance, into the nose. Numerical information such as the area at certain distances and volumes between certain points in the nose can be obtained.
In addition to providing a means of establishing nasal obstruction that may adversely influence smell testing, this device has multiple applications. These include surgical pre/post comparisons, nasal symmetry assessment, allergen challenge recording, and quantification of the nasal effects of decongestants, hay fever, and viral infections.
