OBJECTIVES/HYPOTHESIS Demonstrate that the Nasal Obstruction Balance Index (NOBI) model fulfils unmet need of improving unilateral correlation between subjective and objective nasal obstruction outcome measures identifying more obstructed side. Improve airway measurements (nasal inspiratory peak flow [NIPF] acoustic rhinometry [AR]) Visual Analogue Scale for (VAS-NO) scores. assessment asymmetr...

The purpose of the study was to measure nasal passageway dimensions in guinea pigs and rats by use of acoustic rhinometry (AR) and by a previously described fluid-displacement method (FDM) (Straszek SP, Taagehoej F, Graff S, and Pedersen OF. J Appl Physiol 95: 635-642, 2003) to investigate the potential of AR in pharmacological research with these animals. We measured the area-distance relation...

Background Common sinonasal disorders include chronic rhinosinusitis (CRS), allergic rhinitis (AR), and a deviated nasal septum (DNS), which often coexist with shared common symptoms including obstruction, olfactory dysfunction, rhinorrhea. Various objective outcome measures patient-reported (PROMs) are used to assess disease severity; however, there is limited evidence in the literature on cor...

A comprehensive study that compared acoustic rhinometry (AR) data to computed tomography (CT) data was performed to evaluate the accuracy of AR measurements in estimating nasal passage area and to assess its ability of quantifying paranasal sinus volume and ostium size in live humans. Twenty nasal passages of 10 healthy adults were examined by using AR and CT. Actual cross-sectional areas of th...
