Position paper on nasal obstruction: evaluation and treatment.
2018
Nasal obstruction (NO) is defined as the subjective perception of discomfort or difficulty in the passage of air through the nostrils. It is a common reason for consultation in primary and specialized care and may affect up to 30%-40% of the population. It affects quality of life (especially sleep) and lowers work efficiency. The aim of this document is to agree on how to treat NO, establish a methodology for evaluating and diagnosing it, and define an individualized approach to its treatment. NO can be unilateral or bilateral, intermittent or persistent and may be caused by local or systemic factors, which may be anatomical, inflammatory, neurological, hormonal, functional, environmental, …
Clinical Assessment of Nasal Airway Obstruction
2019
For the evaluation of nasal airway obstruction physical examination, anterior rhinoscopy, laboratory workup, imaging studies, and rhinomanometric studies may be required. Laboratory workup may consist of counts of neutrophil investigating infectious diseases, eosinophil for allergy-related disorders, and mast cell in food allergy. Imaging workup contains computed tomography (CT) and magnetic resonance imaging. Physically based studies involve rhinomanometry and acoustic rhinometry techniques. Nasal resistance is responsible for more than 50% of the resistance of the total airway. Nasal resistance is made up of two layers: the deeper layer consists of underlying bone, cartilage, and muscle, …
Relationships among nasal resistance, age and anthropometric parameters of the nose during growth
2018
Background: Children generally have a higher nasal resistance than adults. Growth changes the size and different anthropometric parameters of the nose. Logarithmic effective resistance and logarithmic vertex resistance were introduced as physically correct parameters for nasal obstruction. The previously published classification of obstruction derived from 36,500 measurements is missing data for patients aged 7 to 19 years. Methodology: Rhinomanometry was performed before and after decongestion with 9 different anthropometric measurements in 225 children and adolescents. Correlations among age, anthropometric measurements, and logarithmic effective and vertex resistance were determined for …
Objective measures of nasal function
1995
Numerous techniques to objectively measure nasal function are available to the rhinologic surgeon. Rhinomanometry, acoustic rhinometry, laser Doppler flowmetry, saccharin transport time, determination of ciliary beat frequency, and olfactory and trigeminal event-related potentials are all techniques in current use. Rhinomanometry is the standard clinical tool used to indicate those patients complaining of nasal obstruction who are likely to benefit from septal and turbinate surgery. Acoustic rhinometry permits the precise localization of nasal stenoses and is the best predictor of a patient's postoperative satisfaction. It is, in addition, more sensitive than rhinomanometry in recording cha…
Airway assessment by four-phase rhinomanometry in septal surgery
2011
PURPOSE OF REVIEW This article updates the state of the art in functional ventilation tests of the nasal airway. Multidisciplinary international cooperation has led within the last years to the development of four-phase rhinomanometry (4PR) by eradicating the errors of the 'classic' rhinomanometry. RECENT FINDINGS Physical experiments, mathematical models and comprehensive statistical analyses implicate that the nasal breath consists of four phases of different diagnostic importance. Presuming the motility of the nasal entrance, it is necessary to depict the elastic behavior within the rhinomanometric curve, as well as to use new parameters for the clinical evaluation of the nasal obstructi…
