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 …

In 1903, Minkz0 was the first to use the term" nasal valve" during his description of the main
site of nasal resistance. He placed the nasal valve at the junction between the upper lateral …

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 …

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 …

Examination of rhinomanometric records of 2500 referred adult patients revealed 891
unobstructed noses (Rn< 0.25 Pa/cm3/sec). Topical decongestant reduced respiratory …

• Effects of simulated septal deviations on nasal airflow resistances were assessed by
rhinomanometry in healthy human adults. Obstructions 5× 15 mm protruding 1 to 5 mm into …

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 …

Theoretical considerations of nasal airflow mechanics and surgical implications A
mathematical model relating nasal airflow and pressure, using Bernoulli's equation applied …

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 …

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 …
