    Background & Aim: Objective assessment of nasal airway is helpful in understanding nasal breathing function. Acoustic rhinometry is one of the most commonly used objective measurements of nasal airway. This test has the ability to measure cross-sectional areas of the nose in different distances and volume and also determines the site of minimal cross-sectional area. These variables are different in various areas. Defining these normal values in adult Iranian population, as a criteria for diagnosis and treatment of nasal diseases, can be very helpful. Patients and Methods: A number(180) of adult Iranian population(age:18-60 years) without nasal breathing complaints underwent acoustic rhinometry. The mean volume and minimal cross-sectional area of nose and also correlation of these variables with age, sex, height, smoking habitus, and topical nasal decongestant were assessed. This study is cross sectional and the statistical tests were descriptive statistics, T test and correlation test in SPSS software. Results: In this population total nasal volume is 8.12±0.94cm3 and total minimal cross-sectional area is 0.9±0.17 cm2 before decongestion. There was no correlation between those values and age, sex, height, weight and smoking habitus. There was a significant increase in volume and minimal cross-sectional area after decongestion. Conclusion: Due to volume and minimal cross-sectional area differences in various races, measurement of these values in Iranian population is a proper way for diagnosis of rhinological diseases and treatment(medical or surgical) planning and also helpful for comparison of pre and post operative results after nasal surgeries.
