Rhinomanometry and acoustic rhinometry
When is this exam indicated?
Rhinomanometry/acoustic rhinometry is generally a supportive examination to diagnose and better define the nasal respiratory obstruction in order to evaluate the potential benefit of the intervention.
How is it performed?
The examination is performed in an outpatient facilities; no preparation is required. For rhinomanometry, one nostril is plugged at a time and the patient is asked to breathe through the nose with a mask covering the nose and mouth. For acoustic rhinometry, an adapter is placed alternately over the two nostrils. The examination lasts a few minutes and is generally repeated 5 minutes after the application of a nasal vasoconstrictor.
For a correct execution of the examination, the patient must be cooperative. In case of allergy or contraindication to the use of a vasoconstrictor, it should be avoided.
