Nasal air conditioning in relation to acoustic rhinometry values.

Background: Changes of nasal dimensions can influence the air-conditioning capacity of the nose because of alterations of airflow patterns. The goal of this study was to evaluate the correlation between intranasal temperature and humidity values and nasal dimensions, assessed by means of acoustic rhinometry.

Methods: Eighty healthy volunteers (40 men and 40 women; median age, 51 years; range, 20-84 years) were enrolled in the study.

Dynamic nasal infrared thermography in patients with nasal septal perforations.

Background: Nasal obstruction is a typical symptom in patients with nasal septal perforations. Rhinomanometry and acoustic rhinometry are not reliable in these cases because the perforations generate incorrect results. Infrared thermography camera (ITC) systems allow contact-free intranasal recordings of the nasal surface temperature and the semiquantification of nasal airflow.

Influence of the turbinate volumes as measured by magnetic resonance imaging on nasal air conditioning.

Background: Changes in nasal airflow caused by varying intranasal volumes and cross-sectional areas affect the contact between air and surrounding mucosa entailing alterations in nasal air conditioning. This study evaluates the correlation between nasal air conditioning and the volumes of the inferior and middle turbinates as measured by magnetic resonance imaging (MRI).

Methods: Fourteen healthy volunteers were enrolled.

Dynamic infrared thermography of the nasal vestibules: a new method.

Objective: The surface temperature distribution within the nasal vestibule and the nasal cavity strongly depends on the exact intranasal detection site and point of time during the respiratory cycle. Therefore, conventional temperature measurements e.g.

Early influence of bilateral turbinoplasty combined with septoplasty on intranasal air conditioning.

Background: Too extensive resection of the inferior turbinates (ITs) during nasal surgery leads to a severely disturbed intranasal air conditioning. Data comparing nasal air conditioning before and after turbinoplasty in nasal surgery are still lacking. The aim of this study was to determine the early effect of bilateral turbinoplasty combined with septoplasty on intranasal heating and humidification.
