Nasal Anatomy and Physiology

The anatomy and physiology of the internal nose is not always given appropriate consideration when rhinoplastic surgery is performed. Knowledge of the basic physiologic mechanisms of normal nasal function should be a prerequisite to operating on the external nasal structures because of the close relationship between form and function. Although the goals of rhinoplastic surgery are largely to enhance the cosmetic appearance of the visible portion of the nose, it is incumbent upon the surgeon to respect and preserve the critical roles of those portions that remain unseen.
