Nasal ObstructionJUNENCT06670261
Diagnosis of Respiratory Disorders by the Numerical Modeling.
An observational study of Nasal Obstruction and Deviated Nasal Septum, run by University Hospital, Bordeaux at 1 site in France.
Trial summary
Chronic Nasal obstruction (CNO) is not currently measurable objectively because clinicians use validated declarative self-questionnaires whose results are linked to the level of understanding, the acute or chronic clinical situation, fatigue, psychological state and the desired gain.

About this study
Official title: JUNE Project: Does the Modeling of Nasal Airflows Improve the Pathophysiological Understanding and the Diagnosis of Functional Respiratory Disorders?
Chronic Nasal obstruction (CNO) is not currently measurable objectively because clinicians use validated declarative self-questionnaires whose results are linked to the level of understanding, the acute or chronic clinical situation, fatigue, psychological state and the desired gain. Using numerical simulations of the passage of air in the nasal cavities determining specific airflow parameters, the respiratory comfort of healthy subjects and the CNO of patients treated for this pathology could be explained.
Read the detailed description
CNO concerns 20 to 25% of the general population due to numerous etiologies (septal deviation, polyps, chronic rhinosinusitis, post-therapeutic cancer quality of life…). It disrupts sleep and deteriorates all the compartments of the quality of life sometimes to depression. To date, nobody knows the exact component of CNO which is probably the amalgamation of different mucosal information and all measurement attempts have failed by lack of reliability and reproducibility. This major shortcoming of CNO quantification leads to diagnosis uncertainties, quantification of symptoms and therapeutic. The place of such complementary exam able to do an objective measure of NO is expected by the profession. The Computational Fluid Dynamic Simulation (CDFS) of the air passage would allow a complementary functional analysis to anatomy of the sino-nasal cavities to measure CNO. Such information would reduce the failure rate and unnecessary functional surgeries by 25%, reduce the inappropriate care of patients suffering to obstructive sleep disorders and reduce the financial burden on the health system. No patient follow-up in this study: pseudo-anonymized retrospective clinical and scannographic data from the routine management of patients in rhinosinusology consultations.

What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation coefficient
Correlation coefficient of at least one of the simulation parameters greater than 0.5 with the NOSE score in a healthy population and a pathological population. This parameter could be Pressure (P), Temperature (T), mass exchanges (C) and/or shear stresses (SS).
Measured: at inclusion (day 0)
Secondary outcomes (3)
Physical values of air flow
Physical values of air flow in the normal population and in the pathological population suffering from ONC, during resting breathing for all CFD parameters at 0.5 sec from the start of the respiratory cycle.
Measured: at inclusion (day 0)
flow parameters
Statistical comparison of the flow parameters between these two groups and correlation of clinical data with the flow parameters.
Measured: at inclusion (day 0)
weighting coefficients of the flow parameters
Search for the weighting coefficients of the flow parameters and validation of the equation determining the CNO.
Measured: at inclusion (day 0)
