ABSTRACT
Accurate description of the lesions is necessary for both patients and physicians. It provides permanent records for diagnosis including explanation of lesions, evaluation between pre- and post-treatment, and teaching and medicolegal problems. Among various methods oi documentation of lesions, still photography is the most ideal technique. Photographic documentation in head and neck region using rigid telescope is difficult because this region has relatively narrow canal-like struture and is highly sensitive and difficult to tolerate for insertion of telescope, and it accompany moving problem on swallowing and phonation. Kelly4) pointed out ideal photography should be clear, concise, reproducible, non-invasive, relatively inexpensive, portably equipped, comfortable for the patient and not excessively time-consuming. D’Agostino et al.2) introduced endoscopic photodocumentation system using CCD videocamera attached to Nikon F3 single-lens reflex (SLR) camera for focusing the image. But this system has some inconvenience for setting-up and it is hard to get PentaCAMR video-viewfinder. So, author developed more convenient system using Nikon F4 SLR camera with easily available CCD videocamera and adaptor, and evaluated this usefulness of this new system.
