This study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the Italian version of the NOSE scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction.  
Materials and Methods:
Data was obtained from a total of 233 adult patients, (123 males, 110 females, with a mean age of 43.7 years) with a diagnosis of septal deviation and complaining about nasal obstruction. Anterior active rhinomanometry was used for objective assessment, while the I-NOSE scale and a visual analog scale (VAS) were used for subjective evaluation.
Positive correlations between I-NOSE scores and VAS and rhinomanometric results were found.The higher correlation was demonstrated between the HUNR (higher unilateral nasal resistance) parameter of rhinomanometry and the second item of the I-NOSE scale (Nasal blockage or obstruction). No significant correlation was found between the fourth item of the I-NOSE (Trouble sleeping) and the VAS score. The VAS score appeared mildly, but still significantly, correlated with the HUNR parameter of rhinomanometry.
The correlation between the subjective sensation of nasal patency and the rhinomanometric data proved to be significant. No correlation between subjective sensation of trouble sleeping and rhinomanometric assessment was found. In counselling with patients complaining of nasal obstruction trouble in sleeping should not be considered as a symptom related to nasal obstruction.
