Effects of the nasal valve on acoustic rhinometry measurements: a model study.
The influence of nasal valve on acoustic rhinometry (AR) measurements was evaluated by using simple nasal cavity models. Each model consisted of a cylindrical pipe with an insert simulating the nasal valve. The AR-determined cross-sectional areas beyond the insert were consistently underestimated, and the corresponding area-distance curves showed pronounced oscillations. The area underestimatio...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Value of acoustic rhinometry for measuring nasal valve area.
OBJECTIVE To assess the validity of acoustic rhinometry for measuring nasal valve area in human subjects. STUDY DESIGN A comprehensive study that compared acoustic rhinometry data with computed tomography findings from scans obtained perpendicular to the acoustic axis and perpendicular to the floor of the nose. METHODS Fifty nasal passages of 25 healthy adults with no nasal disease were exa...
متن کاملEffects of paranasal sinus ostia and volume on acoustic rhinometry measurements: a model study.
We used pipe models to investigate the effects of paranasal sinus ostium size and paranasal sinus volume on the area-distance curves derived by acoustic rhinometry (AR). Each model had a Helmholtz resonator or a short neck as a side branch that simulated the paranasal sinus and sinus ostium. The AR-derived cross-sectional areas posterior to the ostium were significantly overestimated. Sinus vol...
متن کامل[Evaluation of the effects of nasal decongestants with acoustic rhinometry].
Acoustic rhinometry is a new method of evaluating the geometrical distributions of the cross-section and volume of the nasal cavity. Its characteristics are that of a nontraumatic procedure requiring minimal time for measurements. Eight males (27-39 years old) without nasal lesions were investigated with acoustic rhinometry before and after unilateral administrations of decongestants. Conventio...
