Abstract

German and American surgeons have developed a laryngoscope and new technique for microdiagnosis and microsurgery, which they say, allows earlier detection and more accurate treatment of laryngeal cancer than is possible with conventional methods.

The new instrumentation consists of a specially designed laryngoscope with an operating microscope which has a 400 mm lens. Its developers, Geza J. Jako, MD, Boston, and Oscar Kleinsasser, MD, Cologne, also have designed accessory attachments for 35 mm color photography, 16 mm color motion pictures, and closed circuit television.

Dr. Jako, who is President of the Institute for Applied Ear Research and senior surgeon at Melrose-Wakefield Hospital, told The Journal that this technique of laryngoscopy provides a magnification of 16 to 25 times that of the conventional type. Therefore, it is possible to differentiate early lesions in the vocal cords such as chronic laryngitis associated with epithelial hyperplasia.

Moreover, using this magnification, the diagnostician may
