Rhinomanometry is a method of measuring nasal airflow and nasal resistance. Despite many technical improvements, there are conflicting opinions on its applicability in the functional diagnosis of the upper airway.
The study was aimed at the assessment of the anterior active rhinomanometry in the diagnosis and monitoring of allergic rhinitis (AR), allergy vaccination, and pharmacotherapy.
The study population consisted of 563 patients with allergic rhinitis and 49 controls. The following items were analysed:
New indexes derived from the raw data were proposed. Own algorithms (computer programs) were used for assessing the reproducibility of measurements and in calculating the nasal comfort limiting values.
There was no significant influence on the rhinomanometry results by the patient's gender and the test side. Nasal resistance was increasing with age (r=0.23; p=0.008). There was a mediocre correlation between nasal resistance and the feeling of nasal blockage (r=0,58; p=0,001), as well as between the asymmetry of nasal flow and the presence of septum deviation in anterior rhinoscopy (r=0,345; p=0,048). Cyclic changes of nasal patency were demonstrated. The nasal comfort limiting values were: nasal flow of 280 cm3 s-1 and nasal resistance of 0,18 Pa cm-3 s (they may be used e.g. in disabilities certification). Using rhinomanometry, it was possible to detect a decrease of nasal patency after injection of a single dose of allergy vaccine (use: monitoring allergy vaccination). Also possible was rhinomanometric detection of the decrease in nasal patency after taking a singe dose of captopril (use: fast, non-invasive and inexpensive monitoring of hypertension pharmacotherapy). A low sensitivity and specificity was demonstrated of the rhinomanometry-controlled nasal provocations carried out according to present criteria and appropriate changes were proposed.
