All mammals, including man, have two nasal passages. However, airflow is not symmetrical,
due to anatomical and physiological factors. The anatomical factors are the fixed structural …

Nasal airway obstruction (NAO) is a common otolaryngic complaint with many potential
causes, frequently structural or inflammatory in nature. Patients typically have multiple …

Current approaches to model nasal airflow are reviewed in this study, and new findings
presented. These new results make use of improvements to computational and experimental …

The changes in nasal function which occur after septorhinoplasty for obstruction were
investigated by anterior rhinomanometry in 15 subjects. Objective and subjective measures …

The purpose of the present study was to assess quantitatively the nasal valve area during
normal inspiratory and expiratory maneuvers. The pressure-flow technique of Warren was …

Nasal obstruction is predominantly a subjective patient complaint. The physical examination
of the nose for nasal obstruction is a subjective evaluation as well. While the history and …

Nasal obstruction can be due to internal and external valve problems that can be seen
before and after rhinoplasty. The main scope of this article is to concentrate on surgical …

The nose acts as a physiologic airway resistor, accounting for around 50% of total airway
resistance. Adequate nasal resistance is essential not only for correct functioning of the nose …

Surgical treatments for nasal airway obstruction (NAO) are commonly offered as part of
otolaryngology practice. Anatomic causes include septal deviation, inferior turbinate …
