ABSTRACT Evaluating nasal cavity airflow is crucial in both fundamental science and clinical settings. While rhinomanometry (RM) effectively assesses global nasal resistance, developing alternative methods for detailed local structural evaluation remains challenging. Here, we report an approach to measure local pressure at multiple positions in the nasal cavity using 3D‐printed models created based on computed tomography data of five healthy individuals. This approach records multiple pressure differential values at arbitrary positions in the nasal cavity during a breathing‐like inhalation/exhalation cycle. The measured data are unique to the corresponding individuals and correlate well with the RM results from human‐assisted breathing using the 3D‐printed models. Our experimental approach will open up possibilities for a deeper understanding of the relationship between fluid dynamics in the nasal cavity and practical air flow in the nasal cavity.
