The use of roentgenography as an aid in diagnosis of diseases of the hypopharynx, larynx, trachea and soft tissues of the neck is of great importance in many cases, particularly when complications of the mediastinum or lungs may exist. A systematic roentgenologic study of the entire respiratory tract is advisable for all patients with laryngeal involvement.

A thorough roentgenologic study of the larynx and trachea was
