Title: Relationship between Nasal Valve Changes and Nasalance of the Voice
Abstract: Objective Investigate the effect of nasal valve changes on nasalance of the voice by using an external nasal dilator strip that widens the nasal valve area. Method Healthy volunteers who had normal nasal and laryngeal findings were enrolled into the study. All volunteers received acoustic rhinometry and nasometry before and while wearing a commercially available external nasal dilator strip. The data with and without nasal strip were compared. Results Twenty‐five subjects were enrolled into the study. After application of the nasal strips, statistically significant increases were observed in the minimal cross‐sectional area of the nasal valve. However, there were no significant changes in nasalance measurements. Conclusion Despite increasing the nasal valve area, application of nasal strips did not cause a significant change in nasalance scores, showing no relationship between the nasal valve changes and nasalance of the voice.
