Abstract
Reflux-associated laryngeal symptoms (RALS) is the process in which chronic laryngeal symptoms are related to gastroesophagopharyngeal reflux.1 Impairment of upper esophageal sphincter (UES) reflexes may predispose to esophagopharyngeal reflux.1 The novel noninvasive nonpharmacologic UES assist device (UESAD) applies external cricoid pressure to augment intraluminal UES pressure by 20 to 30 mm Hg and reduce esophagopharyngeal reflux events.2 This study aimed to assess the therapeutic efficacy of the UESAD in a pragmatic clinical setting, and to identify factors associated with symptom response among patients with suspected RALS.
