The study of the effects of air pollution of the false cord and ventriculus in the glottic region of the laryngeal cavity were performed using scanning electron microscopy, in view point of the defense mechanism of the glottic region due to outer stimulation from rostoration to the irreversible stage. Results were as follows:
1) The cases of sillicosis which were exposed to long term stimulation demonstrated heavy irrevesible changes and alterations in spite of sufficient restoration periods.
2) Cases of ⁶⁰Co irradiation, in particular, 3000rd, demonstrated sufficient recovery after a irradiation period of three to four weeks. 6000rd exposure however, revealed irreversible changes even after a period of irradiation lasting eight weeks.
