Abstract
Background Laryngopharyngeal reflux is a prevalent, not well-understood disease affecting a high proportion of patients who seek laryngology consultation. The objective of this prospective case series is to explore the subjective and objective voice modifications in Laryngopharyngeal reflux (LPR), especially the usefulness of acoustic parameters as treatment outcomes, and to better understand the pathophysiological mechanisms underlying the development of voice disorder. Methods Forty-one patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily for three months. RSI, RFS, Voice Handicap Index (VHI), and Grade, Roughness, Breathiness, Asthenia, Strain and Instability (GRBASI) were assessed at baseline and after three months post-therapy. Acoustic parameters were measured by selecting the most stable interval of the vowel /a/. A study of correlations between acoustic measurements and laryngoscopic signs was conducted in patients with roughness. Statistical analysis was performed using Statistical Package for the Social Sciences (SPSS). Results Significant improvement in RSI, RFS, VHI, jitter, percent jitter, relative average perturbation (RAP), shimmer, percent shimmer, and amplitude perturbation quotient (APQ) was found at 3 months of treatment (p < .05). A correlation analysis revealed significant correlations between the grade of dysphonia, breathiness, asthenia, instability and jitter, percent jitter, RAP, shimmer, percent shimmer and APQ. In dividing our cohort into two groups of patients according to the presence of roughness, shimmer, percent shimmer and APQ significantly improved in patients with roughness, but no positive correlation was found between acoustic parameters and laryngoscopic signs. Conclusion Acoustic parameters can help to better understand voice disorders in LPR and can be used as treatment outcomes in patients with roughness.
