SUMMARY THE IMPORTANCE OF ESOPHAGEAL DISFUNCTION IN THE OCCURENCE OF PATHOLOGIC DISORDERS RELATED TO LARYNX Stress, trauma, feeding style, misuse of the voice and cigarette smoking are some causative reasons of laryngeal disorders like nodules, polyps and contac granulomas. There are same medical reports which have showed us the relationship between the occurence of laryngeal contact ulcers and the esophageal disorders like gastro-esophageal reflux. We investigated whether there was a relationship between the functional disorders of esophagus and the laryngeal disorders in 24 patients with laryngeal pathology and in 17 control patients without any symptoms by using esophagoscopy, esophageal endoscopic biopsy and acid-perfusion test (Bernstein test).
