Nasal physiology is greatly dependent on the physical structure of the nose. Seemingly individual aspects of the nasal cavity collectively affect nasal function. This article reviews pertinent basic nasal anatomy, nasal physiology, and objective measurements of nasal airflow (see image below). An overview of topics relevant to nasal airflow when performing rhinoplasty is also included.
