Advances in endoscopic techniques for examination of the larynx and nasopharynx.

Abstract

The development of the new Hopkins rod indirect laryngoscope with the polished glass rod lens system and fiberoptic lighting promise to revolutionize the indirect examination of the larynx and nasopharynx. The improved optics and lighting facilitate the acquisition of still and moving picture photography for permanent records. Examples of the superior photographic resolution are presented.
