abstract: 'Objectives of the study: The individuals with laryngopharyngeal reflux are prone for aspiration of refluxed contents and so there is a need for aerodynamic evaluation in these individuals. Hence, the present study investigated the aerodynamic characteristics in individuals with Laryngopharyngeal reflux. Study design: Prospective control group design. Method: Thirty laryngopharyngeal reflux subjects and 30 normal subjects participated in the study. Aerodynamic parameters such as vital capacity, mean air flow rate, maximum phonation duration and phonation quotient were measured using Aero Phone Instrument ((Model 6800). Independent t test was employed for statistical inference. Results: The results revealed that the vital capacity and maximum phonation duration values were lower for laryngopharyngeal reflux subjects when compared to normal controls. No significant differences were observed for mean air flow rate and phonation quotient. Conclusions: The results revealed that the laryngopharyngeal reflux individuals showed significant deviations in aerodynamic parameters when compared to normal individuals. Thus study confirms aerodynamic abnormalities in laryngopharyngeal reflux subjects'
