We have experienced observed diseases of the larynx using a new type of rhino-larynx electronic endoscope PENTAX PVE VNL-1530 connected to a video processor PENTAX PVE EPM-3300 (Asahi Optical Co., Ltd.). The electronic endoscope differs from the fiberoptic endoscope in that it contains a small, light-sensitive CCD chip which is attached to the tip of the endoscope. This electronic endoscope has a small CCD camera in its tip portion, which is 5.1mm in diameter, and can thus be passed through the nasal passage into the laryngeal cavity. The dynamic image provided by this system is superior to that obtained by a flexible laryngofiberscope in terms of resolution of detail. Several clinical cases were presented using data from this system.
