Key points
  1. Computational fluid dynamics is the popular method for evaluating airflow.
  2. Rhinomanometry is popular way for measurement of nasal resistance.
  3. Nasal cavity and paranasal sinus have so complicated construction.
  4. We created accurate nasal cavity and paranasal sinus 3D models and evaluated measured and simulation values of nasal resistance.
  5. The length of the inferior turbinate and cross-sectional area of the choana and nasopharynx may affect the nasal resistance.
