Disease relevance of Rhinomanometry

• In 102 randomly selected patients with allergic rhinitis caused by immediate hypersensitivity, nasal provocation tests (NPTs) with allergens were evaluated by means of rhinomanometry, and cytologic examination of the nasal secretions (NSs) was performed [1].
• It is concluded that dosing with 11 mg menthol in subjects with common cold has no effect on NAR as measured by posterior rhinomanometry but causes a marked change in nasal sensation of airflow with a subjective sensation of nasal decongestion [2].
• Measurements of the nasal airway included anterior rhinoscopy (AnR), peak inspiratory nasal flow, acoustic rhinometry, anterior rhinomanometry (ARM), and the saccharin test with rhinitis questionnaire scores providing a symptomatic measurement [3].
• By means of anterior rhinomanometry, the decongestant effect of topically applied phenylpropanolamine (PPA) was evaluated in 40 patients with nasal obstruction [4].

High impact information on Rhinomanometry

• Five and 30 minutes after each allergen provocation, rhinal airflow was measured by means of anterior rhinomanometry and the subjective symptoms obstruction, itching, and rhinorrhea were assessed by means of a standardized visual analog scale [5].
• Total nasal airflow, measured by rhinomanometry, significantly (p <0.05) improved in the fluticasone propionate group compared with the terfenadine group or the placebo group [6].
• Capsaicin induced a dose-dependent decrease in nasal airflow conductance (active posterior rhinomanometry) (p < 0.002) that was greater in patients with allergic rhinitis (0.40 +/- 0.02 to 0.20 +/- 0.03) than in healthy subjects (0.44 +/- 0.01 to 0.35 +/- 0.02) (p = 0.0001) [7].
• 4. Subjective NAR, nasal secretions and rhinomanometry recordings were not modified by intranasal application of saline, NPY or oxymetazoline [8].
• Nasal resistance was measured by passive anterior rhinomanometry (PAR), and changes in histamine threshold were calculated together with the absolute number of sneezes after each challenge [9].

Biological context of Rhinomanometry

• The nasal airway resistance was determined twice prior to and once after the allergen challenge using anterior rhinomanometry [10].
• To investigate the relationship between these two parameters 20 healthy volunteers had nasal resistance to airflow measured by rhinomanometry compared with nasal sensation by visual analogue scoring before and after nasal mucosal vasoconstriction using topical 0.1% xylometazoline [11].

Anatomical context of Rhinomanometry

• The test uses active anterior rhinomanometry and a histamine titration method, challenging both nasal cavities with a metered dose pump [12].
• NAR was measured by posterior rhinomanometry, and expressed as the inspiratory resistance at a flow of 0.5 L/s. Dental impressions were taken to evaluate maxillary arch morphology, allowing measurement of the following distances: intercuspid (ICD), interpremolar (IPD), intermolar (IMD), and maximum hard palate height (MPH) [13].
• Before challenge and on each of 5 treatment days, all volunteers were asked to rate symptom severity and were evaluated for secretion production (weighted tissues), nasal patency (active posterior rhinomanometry), nasal clearance (dyed saccharin technique), eustachian tube function (9-step test), and middle ear status (tympanometry) [14].

Associations of Rhinomanometry with chemical compounds

• A dose-ranging study of fluticasone propionate aqueous nasal spray for seasonal allergic rhinitis assessed by symptoms, rhinomanometry, and nasal cytology [15].
• The objective of the present study was to investigate nasal function by active anterior rhinomanometry with respect to spirometric data and bronchial hyperresponsiveness to methacholine in 9-year-old children [16].
• A preliminary evaluation of the effect of N-acetyl-aspartyl-glutamate on pollen nasal challenge as measured by rhinomanometry and symptomatology [17].
• One week of treatment with the active steroid significantly reduced the nasal secretion compared to placebo as measured with the aid of a symptom score, and significantly reduced the induced nasal blockage measured objectively by means of rhinomanometry [18].
• An established method of nasal provocation was used to determine the effects of topically applied NPY on nasal resistance to airflow measured by anterior rhinomanometry, the protein content of nasal secretions, and the protein content of bradykinin-induced secretions [19].

Gene context of Rhinomanometry

• NAR was measured by posterior rhinomanometry before and 10 min after intranasal administration of SP (10-40 nmol) or MCH (3-12 mumol) [20].
• Rhinomanometry. I. Simple equipment [21].
• Pulmonary function tests, methacholine provocation tests, anterior rhinomanometry, and skin prick tests were performed on the patients [22].
• Five minutes before and five minutes after each challenge, TNR was determined by active anterior rhinomanometry [23].
• Rhinomanometry was repeated after 5, 10 and 20 min (T5, T10, T20) [24].

Analytical, diagnostic and therapeutic context of Rhinomanometry

• The study population consisted of 300 children (ages 8 to 11 years; mean, 9.3 years; 161 male, 139 female), who underwent basal rhinomanometry followed by a decongestion test and a lung function test consisting of spirometry and a methacholine provocation test [16].
• Acoustic rhinometry compared with anterior rhinomanometry in the assessment of the response to nasal allergen challenge [25].
• The diagnostic methodology of these 250 patients included: anamnesis, rhinoscopy, rhinomanometry, skin tests, respiratory function, immunoglobulin levels (IgG, IgA, IgM, IgE), specific IgE and histamine release test [26].
• Fifteen healthy subjects underwent active anterior rhinomanometry and laser Doppler flowmetry prior to and following the topical application of 100 micrograms of xylometazoline to each nostril [27].
• All patients had a thorough medical history, ENT examination with rigid and flexible endoscope, anterior Rhinomanometry (RRM), skin-test for inhalant and alimentary allergens, RAST, audiometric exam, non-specific nasal provocation test (NSNPT) with histamine, using as control the number of sneezes [28].
