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 …

Objective To compare measurements of the nasal valve on computed tomographic images
obtained in the traditional coronal imaging plane with those obtained using the Nasal Base …

Background The objective of this work was to explore the utility of axial computed
tomography (CT) imaging to objectively define a narrow internal nasal valve, and compare …

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 …

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 …

Objectives To quantify changes in the cross-sectional area of the nasal valve after
placement of spreader grafts and flaring sutures and to review clinical outcomes after nasal …

Objectives To measure the width of the nasal septum in the region of the internal nasal valve
using radiographic images to support use of open septorhinoplasty for alteration of the …

The ability to breathe through the nasal passages is a noticeable feature of healthiness and
wellbeing. The nasal airway plays a central role in air heating and humidification, olfaction …

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 …

IN ITS SIMPLEST ANATOMI-cal definition, the nasal cavity may be viewed as a longitudinal
set of crosssectional area segments that act as resistors in series, with the overall resistance …
