Video ENT flexible fiberscopy using the ENT flexible fiberscope and video system is described. ENT flexible fiberscopes (ENT US-30S, US-30P) and a xenon light source (RX-500J) were developed by Machida Opt. Co. A video system composed of a video camera (DXC-1850, DXC-6000), video monitor and videocassette recorder was developed by SONY Co. 3/4 inch U-matic video tapes were used. Patients aged from 14 hrs after birth to 77 years were examined successfully. A clear and enlarged view on the TV monitor was sufficiently reliable to evaluate the disorders. The video fiberscopy was especially useful in the case of congenital stridor in the neonatal period. The use of video home system in this method is difficult at present because of insufficient quality in home video equipment. Some problems to be solved were discussed briefly.
