title: [Medical ENT endoscopic studies in the iron and steel industry].
abstract: 461 chromium- and nickel-exposed steelworkers were otolaryngologically examined by endoscopy. Besides chronic inflammatory diseases of the ear, nose and paranasal sinuses, the clinical diagnosis of leukoplakia and hyperplastic laryngitis was made for 30 workers. In no case a lesion suspicious of cancer was found. Office staff showing no such occupational risk factors served as the control group. It was found that in both groups smoking has to be assumed as the decisive factor for the development of chronic inflammation and precancerous changes in the oral cavity and the larynx.
