In our Cochrane review on laryngeal reflux (LPR) and hoarseness, studies were insufficient to document specific voice related acoustical relations to the larynx. Mostly, the amounts of patients were too low for statistical evidence. Probably there is one disorder, GERD, which in some cases gives laryngeal complaints due to oedema of the arytenoid region shown in Figure 1. There is a lack of voice related acoustical evidence in randomized controlled trials between gastro oesophageal reflux disease (GERD) and LPR. A meta-analysis did not give validated conclusions either . With high speed films it is possible to document treatment effect with reduction of oedema of the arytenoid region, in this way we have new objective measures for prognostic evaluation of LPR. The aim of this prospective randomized study was based on an earlier study, to make an acoustical evaluation: that the speaking voice is a parameter of interest in LPR.
