Abstract
Laryngoendoscopic observations and recordings of dynamic image obtained from patients with laryngeal lesions are performed using a rhino-larynx electronic endoscope system. The electronic endoscope differs from the flexible fiberscope in that it contains a small light-sensitive CCD chip which is attached to the tip of the flexible endoscope. This rhino-larynx electronic endoscope has the small CCD camera in the tip portion of approximately 5mm in diameter and can be passed through the nasal passage into the laryngeal cavity. The dynamic image provided by this electronic endoscope system is superior to that obtained by a fiberoptic endoscope in resolution of the detail. Some clinical cases observed by this system are presented.
