Laryngeal manifestations of gastroesophageal reflux disease

Chronic laryngeal signs and symptoms associated with gastroesophageal reflux disease (GERD) are often referred to as reflux laryngitis or laryngopharyngeal reflux (LPR). It is estimated that up to 15% of all visits to otolaryngology offices are because of manifestations of LPR. Damage to laryngeal mucosa may be the result of reflux of gastroduodenal contents, whether chronic or a single incident. The most common presenting symptoms of LPR include hoarseness, sore throat, throat clearing, and chronic cough. The diagnosis of LPR is usually made on the basis of presenting symptoms and associated laryngeal signs, including laryngeal edema and erythema. The current recommendation for managing these patients is empiric therapy with twice-daily proton pump inhibitors for 1 to 2 months. Other causes of laryngeal irritation are considered in most of those who are unresponsive to such therapy. Surgical fundoplication is most effective in those who are responsive to acid-suppressive therapy.
