Abstract
Advances in technology for diagnostic endoscopic systems have accelerated, and electronic laryngeal videoendoscopic systems have spread rapidly. For further improvement of views of the larynx, we tried closeup imaging by electronic videoendoscope. The following conclusions were obtained:
1. Closeup imaging by electronic videoendoscope showed improvement of the view area, i.e., ventriculus, lower surface of the vocal fold, and subglottic area. More precise observation of the vocal fold vibratory motion was achieved.
2. Good views of the larynx were obtained clinically with the smallest electronic laryngeal videoendoscope in the world.
3. Using spectroendoscopy FICE (Fuji Intelligent Color Enhancement), detection of white lesions was improved. Contrast between the tumor vessels and the white lesions was enhanced. FICE may play an important role in the diagnosis of laryngeal lesions.
