| Abstract | Objective: To assess the effect of medialization surgery and voice therapy on laryngopharyngeal reflux (LPR) in patients who have glottic insufficiency.
Background: Glottic insufficiency (GI) is the incomplete closure of the vocal folds with phonation, causing dysphonia and an increased risk of aspiration. Typical treatments for glottic insufficiency include medialization procedures and voice therapy. Many people who suffer from glottic insufficiency also have laryngopharyngeal reflux. Laryngopharyngeal reflux (LPR) is a common and often silent condition in which acid reflux damages the laryngeal and pharyngeal mucosa. LPR is characterized by extraesophageal symptoms such as hoarseness, chronic cough and throat clearing, globus sensation, chronic rhinosinusitis, and dysphagia. Due to the evidence of symptom overlap between LPR and glottic insufficiency, this study aims to determine whether the standard treatments for glottic insufficiency (voice therapy and medialization procedures) can also reduce the severity of LPR in patients with both conditions.
Methods: A retrospective chart review conducted of patients who visited the office of the senior author, received a diagnosis of LPR and GI, and underwent a medialization procedure and/or received voice therapy. Reflux severity index (RSI) scores and twenty-four-hour pH and manometry testing results will be collected to evaluate voice outcomes pre- and post-intervention.
Results/Conclusions: We will discuss the results of the RSI and manometry studies to determine whether the standard procedures for GI, the medialization procedures and voice therapy, will improve LPR and voice outcomes.
