ABSTRACT
To evaluate the hoarseness of voice by aerodynamic analysis in cases of GERD with reflux posterior laryngitis before and after empiric therapy of omeprazole. Out of 154 newly diagnosed GERD cases with posterior laryngitis, sixty four patients with persistent hoarseness were evaluated clinically, examined by digital videolaryngoscope and underwent aerodynamic analysis in comparison to 22 controlled patients before and after empiric therapy of omeprazole. First group involved 52 patients showed improvement by following the pre and post- hoarseness scores, pre and post endoscopic laryngeal findings scores, and the pre and post- aerodynamic parameters in comparison to the normal controlled group. Second group involved 12 non improved patients. Hoarseness patients in our study fall predominantly into the atypical GERD group [silent refluxers]. It seems that the main value of aerodynamic measurements is to evaluate the levels of hoarseness in GERD cases and monitoring the pre and posttherapeutic changes of voice disorders, and they have limitations in identifying which patient will respond or not to empirical treatment
