Objectives/hypothesis Minimum cross‐sectional area of the nasal passage on CT (CT‐MCA)
is an objective computerised determination of the minimum cross‐sectional area of the nasal …

Background Clinicians who manage nasal obstruction often comment on the shape and size
of the nasal valve (NV) area. However, correlation of the symptoms of obstruction, nasal …

Objectives To assess the cross-sectional area and angle of the internal nasal valve more
accurately by reformatting computed tomography (CT) scans of the nasal airway according …

Introduction: Nasal obstruction is one of the most frequent otolaryngologic complaints; and
the collapse of the internal nasal valve is one the main causes of the nasal air flow …

Many methods and techniques have been proposed for the assessment of the nasal valve,
most requiring special equipment. Furthermore the main focus has been on the internal …

OBJECTIVES: Comprehensive examination of the internal nasal valve (INV) using objective
methods. STUDY DESIGN AND SETTING: In this prospective study, 248 nasal cavities were …

Abstract Objectives/Hypothesis: Disease‐specific quality‐of‐life (QOL) assessment of
patients with nasal valve compromise and symptomatic nasal obstruction has not been …

The nasal valve region plays a key role in nasal breathing. In the international literature, a
variety of techniques have been described to rectify nasal valve compromise, but based on …

Purpose Nasal obstruction is a highly subjective and commonly reported symptom. The
internal nasal valve (INV) is the rate limiting step to nasal airflow. A static INV grading score …

Conclusions. The internal nasal valve (INV) angle in Asians is 21.6°±4.5° and it is
significantly larger than that of Caucasians. The reconstructed CT method has better …
