“…Very few studies have considered the development of upper airway morphology. 3 Clinical techniques for evaluating nasal pathology include visual analog scales, 4 rhinostereometry, 5 video-endoscopy, 6 rhinomanometry, 7 and acoustic rhinometry. 8 A combination of the above techniques is usually employed in practice, based on the specific performance of each technique.…”

BACKGROUND:The human respiratory airway undergoes dramatic growth during infancy and childhood, which induces substantial variability in air flow pattern and particle deposition. However, deposition studies have typically focused on adult subjects, the results of which cannot be readily extrapolated to children. We developed models to quantify the growth of human nasallaryngeal airways at early ages, and to evaluate the impact of that growth on breathing resistance and aerosol deposition. METHODS: Four image-based nasal-laryngeal models were developed from 4 children, ages 10 days, 7 months, 3 years, and 5 years, and were compared to a nasallaryngeal model of a 53-year-old adult. The airway dimensions were quantified in terms of different parameters (volume, cross-section area, and hydraulic diameter) and of different anatomies (nose, pharynx, and larynx). Breathing resistance and aerosol deposition were computed using a highfidelity fluid-particle transport model, and were validated against the measurements made with the 3-dimensional models fabricated from the same airway computed tomography images. RESULTS: Significant differences in nasal morphology were observed among the 5 subjects, in both morphology and dimension. The turbinate region appeared to experience the most noticeable growth during the first 5 years of life. The nasal airway volume ratios of the 10-day, 7-month, 3-year, and 5-year-old subjects were 6.4%, 18.8%, 24.2%, and 40.3% that of the adult, respectively. Remarkable inter-group variability was observed in air flow, pressure drop, deposition fraction, and particle accumulation. The computational fluid dynamics predicted pressure drops and deposition fractions were in close agreement with in vitro measurements. CONCLUSIONS: Age effects are significant in both breathing resistance and micrometer particle deposition. The image/computational-fluid-dynamics coupled method provides an efficient and effective approach in understanding patient-specific air flows and particle deposition, which have important implications in pediatric inhalation drug delivery and respiratory disorder diagnosis.

“…The technician recorded the nasal volume from the first 6 cm (NV 6 ) and MCA between 0 and 2.2 (MCA 1 ) and between 2.2 and 5.5 cm (MCA 2 ). Minimum NV 6 and MCA values on both sides (NV 6-Min and MCA Min ) and for the entire nasal cavity (NV 6-T and MCA T ) were analysed.…”

“…In recent years, four-phase rhinomanometry has been applied clinically. It measures intranasal pressure, flow, and time variables during the inspiratory and expiratory breathing cycle [6]. Acoustic rhinometry detects acoustic signals reflected from the wall of the nasal cavity and calculates the minimum cross-sectional area (MCA) and nasal volume (NV) of the nose [7].…”

Persistent rhinitis (PR) is a chronic disease that affects millions of people. However, it lacks of a useful method, which can indicate the actual severity of the inflammation in PR patients. This study was designed to seek an examination which could reflect the actual severity of PR disease. The serum Phadiatop test, ECP level, four-phase rhinomanometry, and acoustic rhinometry were assessed in 91 adult patients with PR and 10 healthy controls. The serum total IgE was determined in some of the patients and all of the controls. The patients were divided into four groups: ARWO, ARWTO, NARWO and NARWTO. 40% (22/55) of AR and 33.3% (13/36) of NAR patients never complained of persistent nasal obstruction. Serum ECP levels were increased in the ARWO group. Serum total IgE was significantly elevated in the AR groups. MCA(1-Min) and MCA(1-T) were significantly reduced in the ARWO, ARWTO, and NARWO groups. NV(6-Min) and NV(6-T) were decreased in all PR groups, but only some of these differences were significant. In the ARWO group, MCA(2-Min) (r = -0.252), MCA(2-T) (r = -0.377), NV(6-Min) (r = -0.32), and NV(6-T) (r = -0.311) had significant relationships with serum ECP. We recommend acoustic rhinometry as a useful routine tool for the diagnosis of PR, even among patients without persistent subjective nasal obstruction. This technique might reveal the actual status of nasal congestion. An elevated serum ECP level might indicate severe AR and is negatively correlated with the results of acoustic rhinometry.
