Accuracy of acoustic rhinometry measurements.
OBJECTIVES 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 nasal valve areas of both adults and children. ...
متن کاملIntersession Repeatability of Acoustic Rhinometry Measurements in Healthy Volunteers
OBJECTIVES Acoustic rhinometry is a rapid, reliable and non-invasive technique for the evaluation of conditions associated with impaired nasal patency. This study aimed to examine the intersession repeatability of acoustic rhinometry measurements of unilateral and combined nasal parameters in a group of healthy volunteers. METHODS Twenty healthy volunteers were studied. In each subject, acous...
متن کاملNasal cavity geometry of healthy adults assessed using acoustic rhinometry.
UNLABELLED Acoustic rhinometry (AR) has been used as a specific test for nasal patency. AIM this study aimed to set the reference values for nasal cavity cross-section geometry in healthy adults through AR. STUDY DESIGN this is a clinical prospective study. MATERIALS AND METHOD thirty volunteers (14 males and 16 females) without signs of nasal obstruction and aged between 18 and 30 years ...
متن کاملAcoustic rhinometry measurements in stepped-tube models of the nasal cavity.
Stepped-tube models with a constriction in the anterior section were used to evaluate the effects that nasal valve passage area and nasal cavity shape have on acoustic rhinometry (AR) measurements. The AR-determined cross-sectional areas beyond a constriction of small passage area were consistently underestimated, and the corresponding area-distance curves showed pronounced oscillations. Also, ...
متن کاملAdult nasal volumes assessed by acoustic rhinometry.
UNLABELLED Acoustic rhinometry allows an objective and non-invasive assessment of nasal geometry. AIM The present study aimed at determining the volumes of specific segments of the nasal cavity in healthy adults including the nasopharynx, using acoustic rhinometry. STUDY DESIGN A clinical prospective analysis. CASES AND METHOD Thirty volunteers with no evidence of nasal obstruction, aged ...
