title: [How can hyperreactive rhinopathy be modified surgically? II: Acoustic rhinometry and anterior turbinoplasty].
abstract: By means of the acoustic reflection technique, or acoustic rhinometry, all cross-sectional areas of the upper airway can be measured by an acoustic signal. In this paper, the normal mean curve of 134 normal probands is determined. This normal curve shows the minimum cross-sectional area (I-notch) to be located at the Isthmus nasi. The second narrowest segment of the nasal cavity is located at the head of the inferior concha (C-notch). In patients with turbinate hypertrophy due to allergic or vasomotor rhinitis the minimum cross-sectional area is sited at the head of the inferior turbinate. Furthermore, acoustic rhinometry allows the exact size and location of the congested mucosa to be determined following provocation with allergens in patients with allergic rhinitis. Acoustic rhinometry could further demonstrate why nasal breathing in patients with turbinate hypertrophy improves in the long term after anterior turbinoplasty: in this operation the narrow cross-sectional areas at the head of the inferior turbinate are enlarged. Acoustic rhinometry not only allows the location and size of the various deviations of the nasal structures to be distinguished from normal (valve stenosis, septal deviation, turbinate hypertrophy, tumor masses), but also allows an exact demonstration of the efficacy of rhinosurgical techniques.
