While the nose has many functions, including warming and humidification of inhaled air and olfaction, the function to which we refer most is airflow. Presumably, the bony-cartilaginous skeleton of the nose has evolved for a reason. Indeed, anthropologic studies have supported the notion that features of the human nose developed in response to the need for moisture conservation as activity of the genus Homo shifted to more open and arid environments.1 Therefore, any maneuvers that change this structure, including trauma, iatrogenic causes, and senescence, may affect nasal airflow. Recognition of the importance of structural integrity of the nasal framework underlies the modern approach to functional rhinoplasty.
