Impact of External Nasal Dilator on the Rhinogram (ARENDS)
The aim of this study is to present new data for a better understanding of the anatomic correlation of these two notches.
This study included 32 nasal cavities (16 individuals) with external nasal dilator strip (Breath Right®) and after decongestion (0.05% oxymetazoline chloride applied as an aerosol spray);
|Nasal Obstruction||Drug: External Nasal Dilator Strip; 0.05% oxymetazoline chloride|
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Acoustic Rhinometry: Impact of External Nasal Dilator on the Two First Notches of the Rhinogram|
|Study Start Date:||June 2010|
|Study Completion Date:||December 2010|
|Primary Completion Date:||July 2010 (Final data collection date for primary outcome measure)|
|External nasal dilator, decongestion||
Drug: External Nasal Dilator Strip; 0.05% oxymetazoline chloride
External Nasal Dilator Strip placed above the upper lateral cartilage; 20 minutes after decongestion with 0.05% oxymetazoline chloride applied as an aerosol spray (two times); after decongestion with ENDS.
Other Name: Breath Right®
Acoustic rhinometry is more accurate in the anterior portion of the nasal cavities, from the nostril to the nasal valve (NV), the most important site of nasal obstruction. Literature presents different opinions regarding the anatomical correlation of the two notches at the beginning of the rhinogram curve in normal adult Caucasian individuals.
This prospective study included 32 nasal cavities under the following conditions: 1st - basal condition; 2nd - with external nasal dilator strip (ENDS) (Breath Right®); 3rd - after decongestion (0.05% oxymetazoline chloride applied as an aerosol spray); 4th - after decongestion with ENDS.
