OBJECTIVES: This study aims to investigate the effects of reflux treatment in voice disorders in laryngopharyngeal reflux (LPR) patients using acoustic analyses and the relationship between scoring systems. PATIENTS AND METHODS: A total of 84 LPR patients (18 males, 66 females; mean age 43.1±11.3 years; range 18 to 73 years) were evaluated using reflux symptom index (RSI), reflux findings score (RFS), videolaryngostroboscopic examination, and acoustic analysis with Dr. Speech 4 before LPR treatment and at the first and third months after treatment. RESULTS: Maximum phonation time, fundamental frequency (F0), jitter, and shimmer scores did not show any statistically significant alteration at the posttreatment period according to pretreatment scores (p>0.05). However, the alteration in Harmonics-to-Noise ratio and Signals-to-Noise ratio scores were statistically significant (p=0.017 and p=0.003, respectively). Reflux symptom index results showed significant positive correlation with F0 at the pretreatment, and at posttreatment first and third month evaluations (Spearman's rank correlation coefficient [rho]=0.246, p=0.024; rho=0.300, p=0.006; rho=0.305, p=0.005, respectively). CONCLUSION: The relationship between the parameters of acoustic analysis and RSI and RFS values seems to be controversial for diagnosis and follow-up of LPR patients, requiring further investigations.
