Does nasal obstruction mean that the nose is obstructed
TLDR
The relationship between subjective nasal obstruction and the corresponding anatomic and physiological nasal parameters using acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF) is evaluated.Abstract:
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).
Study Design: Two thousand five hundred twenty-three consecutive patients were included in this cross-sectional study. Eligible subjects were adults referred to the Ear, Nose, and Throat Department, Sorlandet Hospital, Kristiansand, Norway, for evaluation of chronic nasal or sleep related complaints.
Methods: Subjects underwent AR and nasal flow measurements. Subjective grading of nasal obstruction was obtained by a nasal obstruction visual analogue scale. Associations between nasal obstruction visual analogue scale scores, AR, and PNIF were assessed using multiple linear regression, adjusting for age, gender, body mass index, and asthma, allergy, and smoking history.
Results: The sense of nasal obstruction was associated with nasal cavity volumes in both anterior and middle segments of the nasal cavities, with minimal cross-sectional areas in middle segments and for the nasal cavity as a whole, and with PNIF. Associations with minimal cross-sectional areas in anterior segments did not reach significance.
Conclusions: The present study demonstrates highly significant associations between the subjective sensation of nasal obstruction and corresponding measures for nasal cavity volume, area, and airflow. We conclude that AR and PNIF are valuable objective instruments for evaluation of subjective nasal obstruction.read more

A Systematic Review of Patient-Reported Nasal Obstruction Scores: Defining Normative and Symptomatic Ranges in Surgical Patients
TL;DR: It is shown that normative and abnormal value ranges for NOSE and VAS can be established for clinical use and that these measures can be used as a clinically meaningful measure of successful surgical outcomes.

Measurements of nasal airflow and patency: a critical review with emphasis on the use of peak nasal inspiratory flow in daily practice
TL;DR: 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.

Changes in nasal airflow and heat transfer correlate with symptom improvement after surgery for nasal obstruction
TL;DR: Moderate linear correlations with patient-reported symptoms were found for airflow, heat flux, unilateral allocation of airflow, and unilateral nasal resistance as a fraction of bilateral nasal resistance when calculated on the most obstructed nasal side, suggesting that these variables may be useful for evaluating the efficacy of nasal surgery objectively.

TL;DR: The main focus is on exploring the role of nasal endoscopy, radiographic imaging, acoustic rhinomanometry and other diagnostic tests that assist in the diagnosis of nasal airway obstruction.

TL;DR: Preliminary results suggest a possible correlation between unilateral NR and patient-reported symptoms and imply that analysis of unilateral obstruction should focus on the affected side, and a formal investigation is needed to determine if these variables are correlated.
