Disease relevance of Rhinometry, Acoustic

• The results presented in this study demonstrate that acoustic rhinometry has great potential as a reproducible method for the objective assessment of nasal obstruction occurring in nasal allergen challenge studies [1].
• Nasal hyperreactivity to methacholine measured by acoustic rhinometry in asymptomatic allergic and perennial nonallergic rhinitis [2].
• Anterior to posterior cross-sectional profiles of the sinonasal airway were obtained from acoustic rhinometry and segmented coronal HRCT images and compared in five patients having complaints of nasal obstruction and chronic sinusitis [3].

High impact information on Rhinometry, Acoustic

• Montelukast did not significantly affect upper respiratory responses, as measured by means of symptom scores (P =.43) and changes in acoustic rhinometry (P =.078) [4].
• Subjects were then challenged with antigen or diluent (control), and their responses were monitored by using acoustic rhinometry [5].
• Nasal airway changes assessed by acoustic rhinometry and mediator release during immediate and late reactions to allergen challenge [6].
• Effects measurements included assessment of bronchial reactivity, measurement of specific airway conductance, spirometry, acoustic rhinometry, nasal lavage, tear-fluid cytology, a CO2 eye-provocation test, evaluation of eye redness, and subjective sensations [7].
• Serum octreotide and GH data were subjected to pharmacokinetic analyses, and local nasal effects were evaluated by acoustic rhinometry [8].

Chemical compound and disease context of Rhinometry, Acoustic

• The effects of antigen and histamine on the changes of nasal passage patency in 112 guinea pigs with or without allergic rhinitis were evaluated by acoustic rhinometry [9].
• Cross-sectional areas and nasal resistance were measured by acoustic rhinometry and rhinomanometry before and after topical application of 1% phenylephrine solution in 32 patients with nasal obstruction symptoms [10].

Anatomical context of Rhinometry, Acoustic

• The nasal cavity dimensions were measured by acoustic rhinometry and the olfactory function as the threshold for the sense of smell of butanol [11].
• Furthermore, acoustic rhinometry allows exact measurements of size and location of the congested mucosa following challenge with allergens in patients affected with allergic rhinitis [12].
• We measured symptoms, diary card, and rigid endoscopy scores, acoustic rhinometry, middle meatal swabs, blood tests--CRP, ESR, WBC, and eosinophil count [13].
• Using a mathematical model, we integrated the sigmoid curves DeltaP/Q of rhinomanometry with the cross-sectional areas obtained using acoustic rhinometry, thus obtaining the normal distribution of differential and cumulative nasal resistances [14].
• Nasal patency was measured by acoustic rhinometry, and eosinophilic cationic protein (ECP), myeloperoxidase (MPO), lysozyme and albumin were analyzed in nasal lavage fluid (NAL) [15].

Associations of Rhinometry, Acoustic with chemical compounds

• Histamine, 40-800 microg, intranasally into each nostril, induced significant blockage of the nasal airway in normal human subjects, as measured by acoustic rhinometry [16].
• RESULTS: Acoustic rhinometry revealed a significant difference in favour of steroid treatment (P < 0.05) comparing nasal volumes before and during season [17].
• Nasal mucosal swelling was assessed with acoustic rhinometry before and after nasal decongestion with oxymetazoline and was analysed for the crosssectional area (4cm from the nostril) and the volume between 3.3 and 4cm from the nostril [18].
• OBJECTIVE: To evaluate the reproducibility of PNIF and acoustic rhinometry following nasal lysine-aspirin challenge in AIA [19].
• 2. Twenty normal healthy volunteers underwent nasal challenge with either histamine or bradykinin, 100 micrograms to 1000 micrograms, and responses were assessed by acoustic rhinometry [20].

Gene context of Rhinometry, Acoustic

• Furthermore, acoustic rhinometry and s-ECP reflect the impact of nasal steroid therapy on seasonal allergic rhinitis [17].
• ETS-S and ETS-NS subjects differed in correlations between bilateral subjective and objective measures: ETS-S subjects showed significant correlation between baseline congestion and NAR; in contrast, ETS-NS subjects showed significant correlation between baseline congestion and acoustic rhinometry [21].
• These findings correlate with a significant increase in cross-sectional diameter at the Isthmus nasi revealed by acoustic rhinometry 3 months postoperatively [22].
• Most psychophysical tests (e.g., Continuous Performance Test) turned out to be suitable, but physiological tests were either heavily disturbed by technical problems (e.g., portable electrogastrography), or biased by application techniques (e.g., acoustic rhinometry), or were simply too time-consuming (e.g., PC-based voice analysis) [23].

Analytical, diagnostic and therapeutic context of Rhinometry, Acoustic

• Measurement of nasal conditioning, active anterior rhinomanometry (AAR), acoustic rhinometry (AR), and clinical symptom evaluation were performed before and after nasal allergen challenge with allergen extracts from house dust mites [24].
• Evaluation of acoustic rhinometry in a nasal provocation test with allergen [25].
• In this study, we investigated the effects of smoking and nicotine, an important constituent of cigarettes, on the nasal patency using acoustic rhinometry (AR) and an in vitro bioassay technique [26].
