- Abstract
Laryngopharyngeal reflux (LPR) is an inflammatory condition suspected to be associated with dysphonia. In this study, we investigated multidimensional perceptual, aerodynamic, and acoustic voice changes in patients with clinically diagnosed LPR compared to healthy participants. We prospectively included 80 outpatients with Reflux Finding Score (RFS) >7 and Reflux Symptom Index (RSI) >13 from September 2013 to April 2016 and we compared clinical and voice quality assessments of these patients with 80 healthy participants. Statistically significant differences were found between groups with regard to Voice Handicap Index, perceptual voice quality (grades of dysphonia, roughness, strain, breathiness, asthenia, and instability), phonatory quotient, percentage jitter, percentage shimmer, peak-to-peak amplitude variation, standard deviation of fundamental frequency, and noise to harmonic ratio. Granulation score of RFS was found to affect the highest number of acoustic parameters. We did not identify significant correlation between vocal fold edema and objective voice quality measurements. This study supports that patients with LPR have significant deterioration of both subjective and objective voice quality compared to healthy participants.
