Simulation study demonstrates that computational fluid dynamics and the Q criterion enable quantitative nasal airflow analysis, highlighting accessible workflows for anatomical airway modeling.
The short training time for new user without a prior experience in image segmentation and 3-D mesh editing is an important advantage of this type of research. Both CBCT and CT are useful for model building. However, CBCT may have limitations. The Q criterion in CFD illustrates the considerable complication of the nasal flow and allows for direct evaluation and quantitative comparison of various flows and can be used for the assessment of nasal airflow.
