title: [Acoustic rhinometry. A new method for objective assessment of the nasal airway dimensions].
abstract: Acoustic rhinometry is a new and simple method for assessment of nasal airway dimensions. An audible sound signal generated at the bottom of a tubular probe is transmitted into the nasal cavity via an anatomically fitted nosepiece. An area-distance relationship describing the airway geometry is created by comparing the incident and the reflected sound signal. The technique is quick, accurate, reproducible, non-invasive, has no adverse effects, is independent of airflow, and requires minimal co-operation. Several recent studies have established acoustic rhinometry as an important investigative tool in rhinology. It is well suited to illustrate normal physiology of the nasal mucosa, to document deleterious effects of exposure to irritants and to monitor the effect of surgical and medical therapy. A newly developed miniprobe has, in our experience, proven to be uniquely suited for studying the nasal airways of infants and small children. Considering its advantages, acoustic rhinometry deserves an important position in rhinological research and practice.
