Laryngospasm Management with Proton Pump Inhibitors

Mechanism of Action and Laryngeal Protection

The American Academy of Otolaryngology-Head and Neck Surgery suggests that PPIs suppress gastric acid secretion for up to 36 hours, reducing acidic refluxate that reaches the laryngopharynx and causes mucosal injury 1
PPIs may reduce laryngeal hyperreactivity by healing chronic laryngitis, characterized by erythema, edema, and surface irregularities of the vocal folds and arytenoid mucosa, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 2, 3
Chronic inflammation from reflux increases laryngeal sensitivity and reactivity, according to the American Academy of Otolaryngology-Head and Neck Surgery 2
Mucosal damage from reflux can predispose to laryngospasm episodes, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 3

The American Academy of Otolaryngology-Head and Neck Surgery recommends considering PPIs when laryngoscopy demonstrates objective signs of chronic laryngitis, such as erythema, edema, redundant tissue, or surface irregularities of the interarytenoid mucosa, arytenoid mucosa, posterior laryngeal mucosa, and/or vocal folds 3, 4
A treatment duration of 8-12 weeks is optimal for extraesophageal reflux symptoms, according to Clinical Gastroenterology and Hepatology 5
Meta-analyses show no advantage for PPIs over placebo for GERD-related chronic laryngitis, with a relative risk of 1.28 (95% CI 0.94-1.74), as reported by Clinical Gastroenterology and Hepatology 5

Direct visualization through laryngoscopy is essential to identify objective signs of laryngeal inflammation before initiating PPI therapy, as recommended by the American Academy of Otolaryngology-Head and Neck Surgery 3, 4
PPIs are most appropriate when patients have both laryngeal symptoms and typical esophageal reflux symptoms, such as heartburn or regurgitation, according to Clinical Gastroenterology and Hepatology 5
Lifestyle modifications, including avoiding food intake 2-3 hours before recumbency, elevating the head of the bed, weight loss if overweight or obese, and avoiding trigger foods, can be beneficial, as suggested by Clinical Gastroenterology and Hepatology 5

Long-term PPI use carries risks, including hip fractures in older adults, vitamin B12 deficiency, iron deficiency anemia, and increased pancreatitis risk, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 2, 4
Laryngoscopic findings have poor inter-rater reliability and can be present in healthy individuals without reflux, according to the American Academy of Otolaryngology-Head and Neck Surgery 2
