Fig. 1 Findings from Models 1 and 2
Fig. 2 The results of nasal resistance in Models 1 and 2 in the numerical simulation and the comparison of nasal resistance between the simulation and measurement situations (the value of inspiration Δ100 Pa of nasal resistance R [Pa/cm3/s])
Fig. 3 Velocity vector of Models 1 and 2
(a) Velocity vector of Model 1. The speed suddenly decreased near the choana (△).
(b) Velocity vector of Model 2. The speed remained unchanged compared with model 1 (△).
Fig. 4 Streamlining of Model 1; view from the front
(a) Right open streamline. Ventilation in the maxillary sinus and ethmoidal sinus; however, ventilation in the frontal sinus was not observed.
(b) Left open streamline. Ventilation of the frontal sinus and maxillary sinus was not observed.
Fig. 5 Streamlining of Model 2; view from the front
(a) Right open streamline. Ventilation of the frontal sinus and maxillary sinus was not observed.
(b) Left open streamline. Ventilation of the frontal sinus and maxillary sinus was not observed.
Fig. 6 Area of the posterior end of the inferior turbinate and nasopharyngeal section of Models 1 and 2
A comparison of the cross-sectional areas showed that the cross-sectional areas of Model 1 have changed significantly.
