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 nasalExpand
Objective monitoring of nasal patency and nasal physiology in rhinitis
TLDR
Moves of nasal responsiveness are at present largely confined to research studies investigating disease mechanisms in allergic and nonallergic rhinitis, and are insufficiently standardized to be applied to multicenter clinical trials but could be used in limited-center studies to gain insight into the regulatory effects of different therapeutic modalities. Expand
Objective Evaluation of Nasal Dimensions in Children with Acoustic Rhinometry
TLDR
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. Expand
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
TLDR
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. Expand
Measuring Nasal Obstruction Outcomes.
TLDR
Methods of measuring nasal obstruction outcomes include both objective anatomic and physiologic measurements, as well as subjective patient-reported measures, which provide a summary of current nasal obstruction outcome measures. Expand
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 andExpand

TLDR
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. Expand
Mometasone Furoate Nasal Spray Provides Early, Continuing Relief of Nasal Congestion and Improves Nasal Patency in Allergic Patients
TLDR
MFNS, 200 micrograms, showed onset of nasal congestion relief at 6 hours and duration of action beyond 24 hours postdosing, and Objective and subjective assessments were correlated in subjects with maximal (placebo) or minimal (MFNS treatment) congestion symptoms; both assessments were correlation with improved QOL. Expand
Comparison of Anatomic, Physiological, and Subjective Measures of the Nasal Airway
TLDR
Validated anatomic, physiological, and subjective nasal measures may assess different aspects of the nasal airway and provide complementary information. Expand
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.

Evaluation of acoustic rhinometry in a nasal provocation test with allergen
TLDR
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. Expand
The Role of Acoustic Rhinometry in Nasal Provocation Testing
TLDR
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. Expand
Nasal histamine challenge in nonallergic and allergic subjects evaluated by acoustic rhinometry
TLDR
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. Expand
The value of acoustic rhinometry in assessing nasal responses to cat exposure.
TLDR
It is concluded that although AR does provide an objective measure of nasal response to allergen exposure, it has significant limitations, evidenced by the lack of correlation with symptoms, the inability to measure a dose response, and the changes noted even among the control subjects. Expand
Objective measurement of nasal airway dimensions using acoustic rhinometry: methodological and clinical aspects
TLDR
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. Expand
Assessment of nasal cycle by acoustic rhinometry and rhinomanometry.
TLDR
Classic nasal cycle is not a universal phenomenon, which can be abolished by the application of decongestant, but a spontaneous fluctuation in nasal patency can be documented every 10 minutes with irregular pattern, frequency, and amplitude. Expand
Acoustic rhinometry: values from adults with subjective normal nasal patency.
TLDR
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. Expand
The upper and lower airway responses to nasal challenge with house‐dust mite Blomia tropicalis
TLDR
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. Expand
Evaluation of nasal cavity by acoustic rhinometry in Chinese, Malay and Indian ethnic groups.
TLDR
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. Expand
Acoustic rhinometric evaluation of the nasal response to exercise in patients with nasal septal deviation.
TLDR
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. Expand
