Abstract

The variation of ostium geometry in human nose is highly debatable. The ways it affects the airflow pattern within the main nasal cavity and maxillary sinus itself remains unclear. Further studies on this matter are valuable particularly in the medical field. Therefore, the purpose of this study is to investigate the effect of ostium number, position and diameter (3~15mm) on the airflow behavior within the nasal cavity and maxillary sinus. As the results, within the maxillary sinus, the streamlines change with variation of the ostium. In case of the mass flow rate, the flow entering the sinus increases as the ostium size widened and with the presence of multiple ostia. To conclude, ostium variations especially in size and number do effects the airflow pattern particularly within the sinus itself.
