Background And Aim: Voice-related complaints are the most common extraesophageal manifestation of gastroesophageal reflux disease (GERD). The aim of this study was to compare objectively measured voice parameters in normal subjects and patients with GERD and to assess the impact of antireflux surgery on these parameters in patients with reflux disease.
Methods: Normal subjects and patients with reflux symptoms were asked to read a standardized, phonetically balanced text while the impedance across vocal cords was recorded using electroglottography.
