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.
