There is confusion in the literature concerning the physiology and pathology of the nasal
valve, and some debate as to whether there is one valve or two. In an attempt to clarify these …

Fifteen subject underwent nasal pressure gradient studies to determine the resistance
profile of the nose. Seventy-nine per cent of nasal resistance to airflow occurred in the …

Previous observers have suggested that the main site of respiratory airflow resistance is
localized to the vestibular region of the nose. This resistive segment of the airway was …

The nasal valve consists of four distinct airflow-resistive components.(i) The vestibule
terminates in an airflow-resistive aperture between the septum and the caudal end of the …

The nasal valve and nasal valve area are two entities which should not be confused. The
nasal valve area is the narrowest portion of the nasal passage. It is bounded: medially by the …

An account is given of the constituents of the flow resistive nasal valve, their aerodynamic
function, and the essential role they play in processing inspiratory air. The relatively fixed …

A systematic surgical approach to nasal valve abnormalities depends on adequate and
precise exposure of the abnormality to be corrected and is facilitated by the use of …

The nasal valve is defined as the region of the nasal airway bounded by the caudal end of
the upper lateral cartilages and the nasal septum. During inspiration this region of the nasal …

During deep inspiration through a single nasal passage a maximum airflow is reached when
the nasal valve appears to be collapsed. This is due to a Starling-resistor effect. A nasal …

Knowledge of the structure and function of the nasal valve region is required by all who
operate on the nose. This article defines and classifies nasal valve region abnormalities; …
