Nasopharyngoscopes, Flexible, Video
Definition : Flexible nasopharyngoscopes designed to be directly inserted into the nasal cavity, including a television camera on the distal tip for visual examination, biopsy, and treatment of lesions of the nasal cavity, pharynx, and pharyngeal end of the auditory tube. These devices usually consist of an outer sheath, a fiberoptic lighting system, a working channel through which catheters and operative devices are inserted, and a digital camera, typically in the form of a microchip (a charge-coupled device [CCD]). The image is electronically transmitted through wires in the endoscope for external processing, display, and recording.
