Understanding airflow dynamics: a computational study of nasal and oral breathers using patient-specific models

The observed airflow characteristics offer valuable insights into the combined effects of physiological and pathological breathing on airway dynamics. The airflow patterns identified in this study confirm the presence of altered airflow in obstructed nasal airways. Flow parameters, such as velocity streamlines, which illustrate the trajectory of air through the nasal cavity, may serve as supportive indicators for clinical symptoms such as anosmia. The non-invasive nature of CFD allows for a realistic assessment of airway flow behaviour.
