Abstract:
Objective To study the correlation between laryngopharyngeal reflux (LPR) and voice disorders . Methods One hundred and three patients with reflux -related symptoms were recruited .The patients were evalu-ated with reflux symptom index (RSI) ,reflux finding score (RFS) evaluation and 24-hour dural-probe pH moni-toring .Eighty -nine cases with voice disorders were divided into 5 groups :vocal process granuloma (n=18) chron-ic pharyngolaryngitis (n=19) ,vocal polyps (n=15) ,vocal fold leukoplakia (n=21) and Reinke's edema (n=16) . The other 14 patients without voice disorders were the control subjects .Results According 24-hour dural -probe pH monitoring assessments ,48 .3% of the patients with voice disorders showed LPR positive .The positive rate in the vocal fold leukoplakia group (71 .4% ) and Reinke's edema group (75 .0% ) were significantly higher than the control group (35 .7% ) .RSI and RFS of the patients with Reinke's edema were both significantly higher than the control group(P=0 .020 ,P=0 .009) .RSI of the patients with chronic pharyngolaryngitis were significantly higher than the control group (P=0 .019) .The acid reflux episodes ,acid reflux time which except in the supine position of the vocal fold leukoplakia group were significantly higher than the control group .The acid reflux episodes ,acid ex-posure and acid reflux time which all except in the supine position of the Reinke's edema group were significantly higher than the control group .Conclusion The correlations between Reinke's edema ,vocal fold leukoplakia and LPR were stronger .In these two groups ,the acid reflux episodes were higher and acid reflux times were longer .
