Background Acoustic rhinometry (AR) is commonly used as a quantitative assessment of nasal response to nasal allergen challenge (NAC). However, sources of error and physical limitations of various AR area–distance measurements have not been adequately evaluated. 

Nasal Sound Analysis: A New Method for Evaluating Nasal Obstruction in Allergic Rhinitis

Objective: Current measurements of nasal obstruction are unreliable and may be improved with the development of new techniques. The effectiveness of odiosoft‐rhino (OR) in the evaluation of nasal

Objective Evaluation of Nasal Dimensions in Children with Acoustic Rhinometry

Investigating the usefulness of acoustic rhinometry in the evaluation of intranasal dimensions in children found it easy to perform and well tolerated, and a correlation was found between unilateral acoustic values and VAS at baseline, but not after decongestion.

Efficacy of Odiosoft-Rhino in Assessment of Nasal Obstruction: A Comparative Study with Acoustic Rhinometry after Treatment with Budesonide Nasal Spray in Patients with Perennial Allergic Rhinitis

Both AR and OR can assess the efficacy of budesonide nasal spray treatment for nasal obstruction in patients with PAR but, as a simple and noninvasive test, OR can be used with confidence.

Measuring Nasal Obstruction Outcomes.

Nasal testing for novel anti‐inflammatory agents

The nose is much more accessible than the airways to assess the effects of anti-inflammatory therapy. Hence, it is possible to obtain repeated samples of nasal exudates and mucosa cells before and

This review provides an update of the new standard for interpretation and expanded clinical uses of acoustic rhinometry, a rapid, objective, painless, noninvasive technique for assessing nasal airway obstruction.

Comparison of Anatomic, Physiological, and Subjective Measures of the Nasal Airway

Validated anatomic, physiological, and subjective nasal measures may assess different aspects of the nasal airway and provide complementary information.

Assessment of septal deviation effects on nasal air flow: A computational fluid dynamics model

The purpose of this article is to analyze the effects of septal deviation on the aerodynamic air flow pattern compared with that of a normal nose by computational fluid dynamics (CFD) tools.

Indicators for the correct usage of intranasal medications: A computational fluid dynamics study

Intranasal medications are commonly used in treating nasal diseases. However, technical details of their correct administration are unclear.



Evaluation of acoustic rhinometry in a nasal provocation test with allergen

The objective was to validate acoustic rhinometry (AR) in a nasal challenge with allergen and showed good results in both the quantitative and the qualitative aspects of the method.

The Role of Acoustic Rhinometry in Nasal Provocation Testing

Geometric changes of the nasal airway in response to allergen challenge were measured by acoustic rhinometry (AR) and the sensitivity of the method was compared with that of rhinomanometry and the methods were equivalent in sensing the changes in nasal patency due toallergen exposure.

More pronounced spontaneous variations were encountered in the allergic than in the nonallergic subjects, especially with regard to the minimum cross‐sectional areas in the nasal cavities, and the decrease in minimum area during allergen provocation correlated with the level of specific IgE.

Assessment of nasal cycle by acoustic rhinometry and rhinomanometry.

Objective measurement of nasal airway dimensions using acoustic rhinometry: methodological and clinical aspects

The acoustic reflection technique - named acoustic rhinometry - was compared with other methods like MRI, CT, and rhinomanometry and showed reasonable correlation with CT in a cadaver and in 10 subjects in comparison with MRI for the first 6 cm of the nasal cavity.

Acoustic rhinometry: values from adults with subjective normal nasal patency.

It is found that the minimal cross-sectional area (MCA) is located anteriorly in the nasal cavity; in some subjects it is localized at the head of the inferior turbinate and in other subjects more anteriorly at the nasal valve.

The upper and lower airway responses to nasal challenge with house‐dust mite Blomia tropicalis

The house dust mite Blomia tropicalis was found to be the most prevalent domestic mite in Singapore, however, its pathogenicity in allergic airway diseases remains to be investigated.

Evaluation of nasal cavity by acoustic rhinometry in Chinese, Malay and Indian ethnic groups.

There is no significant difference in the normal range of AR measurements among Chinese, Malay and Indian ethnic groups, and AR is able to determine the structural abnormality of the internal nasal cavity caused by septal deviation and inferior turbinate hypertrophy.

Acoustic rhinometric evaluation of the nasal response to exercise in patients with nasal septal deviation.

The results of this study indicated that, in nasal septal deviation, the mucosal response is more prominent in the concave nasal cavities than in the convex nasal Cavities.
