The site of greatest obstruction to airflow through the nasal passages. It extends from the bony cave near the piriform aperture into part of the cartilaginous vestibule of the nose. Synonym: internal nasal valve

The objective of the study was to observe if the dilation of the nasal valve with END interferes with nasal breathing, since it is postulated that there is a difference between the nasal structure morphology of the ethnicities.
In the study, Latera showed significant quality-of-life improvement through one year, using the NOSE score, for nasal obstruction patients with lateral cartilage weakness resulting in nasal valve collapse.
3) Other possible complications include; septal hematoma, aesthetic complications like disfigurement of the nose, and saddling of the nasal bridge; besides these patients are liable to suffer from lifelong functional problems like vestibular stenosis- a possible stenosis of the external and internal nasal valves.
The magnitude of nasal obstruction in a caudally deviated septum is perplexing predominantly due to the fact that the deviation is bounded laterally by nasal valve area.
There are two possible explanations for this: (1) the placebo effect and (2) the fact that only a minimal amount of volume reduction at the nasal valve is required to dramatically improve turbinate aerodynamic features and thus a large improvement in subjective scores.
Use of alar batten grafts for correction of nasal valve collapse.
To evaluate the effects of ENDS and the placebo ENDS on the nasal valve area, volunteers were submitted to acoustic rhinometry using an Eccovision Acoustic Rhinometer, model AR 1003 (Hood Laboratories, Pembroke, MA, USA), as described by Fonseca et al.
The patient was a 31-year-old man who had a deviated nasal septum, turbinate hypertrophy, and a dynamic nasal valve collapse that was worse on the left.
4 ]The tumour was removed along with the lateral nasal wall, which was incised from below, the inferior turbinate to above the middle turbinate and anteriorly at nasal valve area.
Newer applications for the bone-anchored suture system include nasal valve suspension for correction of nasal valve obstruction.
The nasal valve area is the narrowest portion of the nasal passage and hence a common site of nasal airway obstruction.
