To explore the determinants of possible collapse of the nasal valve region, a common cause of nasal obstruction, we evaluated the mechanical properties of the nasal wall. In this study, we determined the nasal cross-sectional area-to-negative pressure ratio (nasal wall compliance) in the anterior part of the nose in six healthy subjects by measuring nasal area by acoustic rhinometry at pressure...

INTRODUCTION Septal deviation is the chief cause of chronic nasal obstruction. In order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. This study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery. MATERI...

The aim of the present study was a validation of acoustic rhinometry (AR) by computed tomography (CT). Six healthy subjects were examined by CT and AR. The CT data were processed in a computer program (AutoCAD), and a virtual three-dimensional model of each nasal cavity was constructed. This model permitted an individual prediction of the center line of the sound wave propagation through the ai...

BACKGROUND Nasal obstruction may contribute to the development of obstructive sleep apnea (OSA). Acoustic rhinometry (AR) measures nasal patency and congestion, which are useful parameters in objectively evaluating nasal obstruction. The nasal obstruction produced by allergic rhinitis may contribute to the development of OSA and can be easily assessed with AR. OBJECTIVE This study was underta...

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 ...

IMPORTANCE Nasal obstruction is common in children and difficult to quantify objectively. Symptom quantification is paramount for surgical and medical decision making. Acoustic rhinometry is a relatively new technique aimed at the objective assessment of nasal obstruction. There is no standardized method for the objective assessment of the pediatric nasal airway. OBJECTIVE To explore the corr...

Statistically, more than 50% of people with moderate to severe asthma also have chronic sinusitis indicating a direct connection between sinusitis and asthma; many studies show the connection between sinus infections and asthma [3]. One 2006 study showed that when compared with those who only have asthma, people who have both sinusitis and asthma tend to have more severe asthma symptoms, may ha...

OBJECTIVES The objective of this study is to determine if acoustic rhinometry (AR) can predict the outcome of radiofrequency ablation (RFA) of the inferior turbinates. PATIENTS AND METHODS Preoperative AR measurements of 19 subjects undergoing inferior turbinate RFA were analyzed before and after decongestant. The average total percentage change in cross sectional area (CSA) 1 and in total vo...
