title: Rhinomanometric evaluation of the improved mechanical therapeutic nasal dilator in patients with anterior nasal obstruction.
abstract: The effectiveness of the Improved Mechanical Therapeutic Nasal Dilator (IMTND) was evaluated rhinomanometrically in 33 patients (mean age: 26 years; range 18-68 years) with anterior nasal obstruction. Using anterior rhinomanometry the patients were observed to have a mean total resistance of 0.376 Pa/cm3/s (range: 0.16-0.87 Pa/cm3/s). There was a significant drop in the inspiratory nasal resistance by 26% after the insertion of the IMTND in the nostrils (p < 0.001). Following decongestion with 1% phenylephrine the resistance decreased by 41%. This difference was statistically significant (p < 0.001). Insertion of the IMTND in the decongested nostrils resulted in even higher and significant decrease in the nasal resistance by 59% (p < 0.001).
