[Xerography in otorhinolaryngology].

This study compares, in the field of oto-rhino-laryngology, the xerography (a radiographic method recently introduced in the Cantonal Hospital of Geneva) with conventional radiography. In spite of the quantity of irradiation which is by far superior, the xerography, with its larger field of information and with its sharpness of outlines, permits a more precise topographic diagnosis, particularly as far as the pharyngolarynx is concerned.
