Objectives/Hypothesis: It is still a matter of controversy to what extent the sense of nasal obstruction is associated with objective measures for nasal space and airflow. Knowledge about this is important in the evaluation of nasal complaints and the planning of its treatment. In this study, we evaluated the relationship between subjective nasal obstruction and the corresponding anatomic and physiological nasal parameters using acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF).

Diagnosis of nasal airway obstruction.
Nasal congestion index: A measure for nasal obstruction
TLDR
The novel Nasal Congestion Index (NCI) was applied to compare subjective nasal obstruction with objective measures for reversible congestion of the nasal mucosa to establish an apples-to- apples comparison.
Objective measurements differ for perception of left and right nasal obstruction.

Position paper on nasal obstruction: evaluation and treatment.
TLDR
The aim of this document is to agree on how to treat NO, establish a methodology for evaluating and diagnosing it, and define an individualized approach to its treatment.
Laterality and severity of nasal obstruction does not correlate between physicians and patients, nor among physicians.
Video-Rhino-Hygrometer: A New Method for Evaluation of Nasal Breathing after Nasal Surgery
TLDR
Video-rhino-hygrometer (VRH) provides an immediate, easy, and noninvasive assessment of nasal respiration and can be used, in association with rhinoscopic data and other instrumental tests, to evaluate nasal breathing in daily ENT practice.
The nasal vestibular body: anatomy, clinical features, and treatment considerations
TLDR
An introductory anatomic description, clinical relevance, and proposed nomenclature for an underappreciated soft tissue focus in the nasal vestibule—the nasal Vestibular body (NVB)—that can contribute to nasal obstruction in a subset of patients is provided.
Measurements of nasal airflow and patency: a critical review with emphasis on the use of peak nasal inspiratory flow in daily practice
TLDR
PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population.
Assessing nasal air flow: options and utility.
TLDR
Assessment of the nasal airway traditionally relied on history and physical examination only but recently, tools have been developed that aid the physician in completing an assessment by measurement of parameters that are directly or indirectly related to airflow.

Repeatability of peak nasal inspiratory flow measurements and utility for assessing the severity of rhinitis
TLDR
This study evaluated the repeatability of PNIF measurements and their association with the signs and symptoms of rhinitis and found that they are associated with nasal obstruction in large populations.
Acoustic rhinometry, rhinomanometry, and the sensation of nasal patency: a correlative study.
TLDR
Each of these objective and complementary measurement techniques provides a more reliable assessment of nasal patency than subjective evaluation by either patient or clinician and can thus provide valuable guidance in management of the symptom of nasal obstruction.
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.
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.
Use of nasal peak flow to assess nasal patency
TLDR
Because PIFna is usually restricted by nasal flow limitation, it is probably superior to PEFna for assessing nasal patency, and comparisons with mouth PEF and/or PIF, suggest that nasal and mouth peak flow should both be measured during home monitoring.
Correlation of subjective sensation of nasal patency with nasal inspiratory peak flow rate.
TLDR
Measurement of nasal inspiratory peak flow rate may be a valuable objective test of nasal patency, and is quick and simple to perform.
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.
Acoustic rhinometry: evaluation of nasal cavity geometry by acoustic reflection.
TLDR
It is concluded that the acoustic method provides an accurate method for measuring the geometry of the nasal cavity and is potentially useful for investigation of physiological and pathological changes in the nose.
Nasal airway geometry: comparison between acoustic reflections and magnetic resonance scanning.
TLDR
In a model of two tubes (nasal cavities) joined in a larger tube (the epipharynx), closure of the anterior part of the latter revealed that the contralateral nasal cavity is likely to cause overestimation of the posterior parts of the epipharyx during AR compared with MRI.
Nasal Airway Volumetric Measurement Using Segmented HRCT Images and Acoustic Rhinometry
TLDR
The use of this semiautomatic segmentation technique is recommended in the validation studies of acoustic rhinometry and in complicated cases as a complementary examination in the evaluation of nasal cavity.
