Adult nasal volumes assessed by acoustic rhinometry [PDF]
Brazilian Journal of Otorhinolaryngology, 2007 Acoustic rhinometry allows an objective and non-invasive assessment of nasal geometry.The present study aimed at determining the volumes of specific segments of the nasal cavity in healthy adults including the nasopharynx, using acoustic rhinometry.A clinical prospective analysis.Thirty volunteers with no evidence of nasal obstruction, aged 18 to 30 ...

A new method of measuring nasal volume is described. It works by extracting air from a closed cavity and measuring the resultant pressure change. To validate this method in the nose, 17 healthy volunteers were examined before and after application of xylometazoline. The apparent volume before decongestion was a mean of 204 ml.

Modelling the reproducibility of acoustic rhinometry
Statistics in Medicine, 2000This paper presents an application of a linear model with correlated errors to the assessment of the precision of acoustic rhinometry in clinical medicine. The design of the reproducibility study involved 20 healthy subjects measured by five investigators with three replicate measurements of four variates taken from the right and left nasal cavities ...

Accuracy of Acoustic Rhinometry Measurements
The Laryngoscope, 2001AbstractObjectives To identify the factors that influence the accuracy of acoustic rhinometry measurements recorded with commercially available equipment.Study Design A simple model was used which consisted of a metal pipe and cylindrical inserts. These inserts comprised various lengths, and aperture dimensions were comparable to, or smaller than, the ...

Acoustic Rhinometry in Preschool Children
Otolaryngology–Head and Neck Surgery, 2007OBJECTIVEThe aim of this study was to measure nasal cavity volume (NV) in preschool children with the use of acoustic rhinometry (AR).STUDY DESIGN AND SETTINGProspective study: 1) Nasal cavity models were used to test the correlations between NV, minimal cross‐sectional area (MCA), and nasal resistance; 2) 97 four‐year‐olds (48 boys, 49 girls) and 137 ...

Posture and Nasal Patency: Evaluation by Acoustic Rhinometry
Acta Oto-Laryngologica, 1994Nasal passage geometry was measured by acoustic rhinometry in 8 healthy medical students (5 males and 3 females, 21-29 years old; mean age 24 years) after 6 min in different postures of head and body. The minimum cross-sectional area (A-min) and volume between the nostril and 7 cm posteriorly were measured on both sides.

Acoustic rhinometry: rationale and perspectives
Journal of Cranio-Maxillofacial Surgery, 1994Acoustic rhinopharyngometry provides a new, non-invasive access to upper airways geometry. In this experimental and clinical study the diagnostic value of acoustic rhinopharyngometry was investigated. In vitro measurements showed adequate accuracy, reliability and spatial resolution within the range of nasal and epipharyngeal dimensions.

Acoustic Rhinometry of Asian Noses
American Journal of Rhinology, 2008Background Each ethnic group has different nasal cavity geometries. The reference value of the minimal cross-sectional area (MCA) and the nasal volume (NV) is mandatory for rhinologic evaluation in regular practice and for research. This study was designed to study the normal value of acoustic rhinometry (AR) in
