Physiological Standards of Acoustic Rhinometry in Suez Canal Area

Abstract

Acoustic Rhinometry (AR) measures the relationship of the cross-sectional area and the distance into the nasal cavity. Great efforts have been done to validate and standardize its clinical use. Inspite of many researches done in Egypt by AR, there are no normal National Egyptian Physiological gold standards of MCA, DMCA and NCV like many other countries. This study was carried out to establish local reference values for AR parameters in healthy normal adults. One hundred and thirty healthy volunteer students of the Faculty of Medicine, Suez Canal University in the age range from 18 to 24 years, who were free from any nasal problems by history and examination, were subjected to AR testing in the
