Abstract

ABSTRACT Background.Laryngeal manifestations of gastroesophageal reflux disease are thought to be prevalent in our society. In general, diagnosis has been primarily based on symptoms. Historically, additional testing has included laryngoscopy, barium swallow, manometry, and single and double probe pH monitoring. Methods.We assessed 96 patients who had symptoms suggestive of reflux laryngitis. We administered surveys grading their symptoms. All patients had standardized videolaryngostroboscopic evaluation and computerized acoustic analysis. Patients then received a uniform regimen of dietary restrictions and omeprazole (a proton pump inhibitor) for 12 weeks, after which they were retested. Results.Using the new laryngoscopic grading system, we found that this regimen produced statistically significant improvement in all symptoms except granulomas. In patients with the pretherapy complaint of hoarseness, acoustic measurements of jitter, shimmer, habitual frequency, and frequency range all showed significant improvement. Conclusions.We conclude that in patients with symptomatic reflux laryngitis, standardized videolaryngoscopy and, if the patient is hoarse, acoustic analysis are useful techniques to aid diagnosis and monitor therapy. Antireflux therapy with omeprazole is effective, and improvement can be objectively shown with the techniques described.
