The change of airflow field caused by structural changes in nasal cavity and paranasal sinuses will affect the physiological function of nose.However,it is always difficult to quantitatively study the airflow field in nasal cavity.The development of computational fluid dynamics(CFD)provides a feasible way to study the changes of nasal airflow.CFD technology based on digital nasal model has a very significant advantage,which has achieved many achievements in the study of normal nasal physiological function,the analysis of airflow characteristics of abnormal nasal structure,the evaluation of surgical curative effect,virtual surgery,and the research of nasal drugs.With the rapid development of computer technology and artificial intelligence,although the clinical application of CFD technology still faces many difficulties,it will have great development potential in nasal clinical application.
