BACKGROUND: The nose is a dynamic organ and is the first point of contact between inhaled air and mucosal surfaces. Within the nasal cavity, there are changes of air flow and pressure occurring during the respiratory cycle, as well as exchanges of heat and humidity, and important immune responses to inhaled antigens and allergens.
METHODOLOGY: This review is a summary for rhinologists covering what is known about airflow within the nose and sinuses and the impact of pathology and treatments on the physical environment of the nasal cavity. The review will concentrate largely on the significant contribution that computational fluid dynamics has had on this field.
RESULTS: The complex anatomical structure of the nasal cavity provides an aerodynamic environment that guides the airflow throughout the nasal cavities. However, anatomical or inflammatory changes can modify the air flow, heat and humidity exchanges, with negative consequences on nasal physiology. Restoration of normal airflow is a key goal to achieve success in the treatment of nasal diseases.
CONCLUSIONS: Computational fluid dynamics is a method of analysis originating from engineering which has been adapted for rhinology. Although still an expensive and laborious technique, it may become a viable diagnostic tool in the future for studying nasal physiology.
