Abstract
The nasal valves are not simple, 2-dimensional cross-sections but rather a complex, 3-dimensional, collapsible, and heterogeneous structure. Historically, the internal nasal valve (INV) is defined by the septum medially, the caudal margin of the upper lateral cartilage laterally, and the inferior turbinate inferiorly. Typically located 1.3 cm deep into the nasal cavity, the INV angle delineated by the upper lateral cartilage and septum typically measures 10° to 15° in the Caucasian population. As computational methods reveal new insights into nasal valve function, a new conceptual framework is needed to guide rhinoplasty surgical decision-making.
