Rhinomanometry is a standard method to objectively evaluate nasal airway patency. Objectives: to measure the nasal airflow and nasal resistance (NR) in healthy adults and to study the effect of gender, height, weight and body mass index (BMI) on rhinomanometric values. Materials and Methods: a cross-sectional study was conducted on 73 young, healthy adults. All subjects underwent anterior rhinomanometry. Results and discussions: Unilateral and bilateral NR were 0.58 + or - 0.20 Pa/cm3/s and 0.28 + or - 0.07 Pa/cm3/s at 150 Pa, respectively. Nasal airflow was 647.97 + or - 177.21 cm3/s. No difference in NR found between male and female. Height, weight and BMI had no effect on NR. Conclusion: Unilateral and total NR in Vietnamese adults were 0.58 and 0.28 Pa/cm3/s, respectively. No correlation exists between NR and anthropometric parameters.
