Acoustic Rhinometry Normal Value Nasal Resistance

This method of Acoustic Rhinometry is performed by doing the cross-sectional areas of the nasal measures by sending a sound pulse that is reflected in the structures of the nose. The reflected signal is received by a microphone andthe analyzed. The role of acoustic rhinometry in the diagnosis is quite limited in comparison with nasal endoscopy, but it is useful to quantify nasal provocation and nasal obstruction. In the future, acoustic rhinometry can be particularly useful in the evaluation of nasal obstruction, children, and is well tolerated with children under 3 years, a group of patients, the objective tests were previously difficult to achieve.
