Abstract

To study the association of Helicobacter pylori (H. pylori) in patients with laryngeal pathologies. Study design: prospective observational study. Tertiary care teaching hospital. One hundred consecutive patients with laryngeal lesions scheduled for microlaryngoscopy were enrolled in the study. Laryngopharyngeal reflux was assessed using the reflux symptom index and reflux finding score. Tissue samples from the laryngeal lesions were taken under general anaesthesia and were screened for the presence of H. pylori using real time polymerase chain reaction (PCR) for ureA genes and histopathological examination. Of the 100 patients, 14 had a significant reflux symptom index score and 35 had significant reflux finding score. The lesions in the study subjects included both benign and malignant laryngeal pathologies. Vocal cord polyps formed more than half of the laryngeal pathology (57%) studied. Our study could not detect H. pylori in any laryngeal lesions by PCR analysis and histopathological examination. H. pylori may not be associated with laryngeal pathologies.
