The Usefulness of a Nasal Dilator for Pharyngo-Laryngeal Lesions

Abstract

The usefulness of a nasal dilator (Breathe Right_TM) for otorhinolaryngologic disorders was reported previously. The purpose of this paper was to evaluate the usefulness of the Breathe Right_TM apparatus especially for pharyngo-laryngeal lesions. Subjects who had usrd the Breathe Right_TM during the night for at least 2 weeks were selected. Eighteen patients including 5 patients who had chronic pharyngo-laryngitis and 13 patients who had abnormal pharyngo-laryngeal sensation were investigated.
All patients received of rhinomanometry measurements. The P (1.0) cmH₂O values on pressure flow curves were evaluated. All except two patients showed a decrease in nasal resistance. These changes were significant.
Eighty percent of chronic pharyngo-laryngitis cases and 62% of abnormal pharyngo-laryngeal sensation cases were improved using the Breathe Right_TM dilator. The overall effectiveness rate of treatment using Breathe Right_TM for pharyngo-laryngeal lesions was 67%.
It can be concluded from our results that the application of the Breathe Right_TM dilator is useful for pharyngo-laryngeal lesions in some cases.
