Abstract :
[en] Pharyngo Laryngeal Reflux (PLR) influences the voice quality : hoarseness, vocal fatigue and hypertonia (Shaw et al, Hopkins et al). Our goal is to measure the influence of the PLR on the voice of 96 subjects by using the Belafsky’s reflux symptom index (RSI) and reflux finding score (RFS). 46 dysphonic patients (26M/24F) constitute the experimental group (EG) and 50 subjects (13 M/33F) without vocal or gastric complaint the control group (CG). All are evaluated by subjective measures (RSI), D-type scale (DS-16, Denollet et al) and objective measures (Video Laryngo Stroboscopy, RFS). The EG shows a RSI score significantly higher on test than on the retest (p=0.002). The specificity of the RSI calculated on the CG amounts to 98 % (chi ²: p < 0,05, Cramer: 0,678). The EG scores are significantly higher than those of the CG (p=0,000) although the CG obtains scores significantly higher as for the eating risk habits (p=0,001). In the EG, we note a correlation between the coffee consumption, the item 9 (pyrosis) (rho: 0,32; p < 0,05 ) and the global RSI score (rho: 0,35; p < 0,05). In the CG, alcohol consumption influences significantly the item 9 (rho: 0,47). The correlations between RSI and RFS are not significant (p < 0.05). The ENT evaluation is severe and probably influences the result. We observe no influence of the gender and of the D-type scale on the RSI scores (p <0.05). The RSI scale is an interesting tool for the detection of RPL.
