The clinical value of stroboscopic videolaryngoscopy (SVL) for the evaluation of laryngeal disorders has been emphasized. Some investigators advocate the use of a flexible fiberscope, while others recommend the use of a rigid telescope for SVL. In order to determine which procedure is more useful for clinical diagnosis, the senior author (E.Y.) performed both fiberscopic and telescopic SVL on 120 consecutive patients who complained of hoarseness. Equipment used included the Olympus ENF-P3 fiberscope, the Nagashima SFT-1 rigid telescope, the Nagashima LS-3A laryngostroboscope, and color video cameras. Our study indicated that stroboscopic images produced by telescopic SVL were superior to those from fiberscopic SVL in the majority of cases. The purpose of this paper is to compare fiberscopic and telescopic SVL, to evaluate the advantages and disadvantages of fiberscopic and telescopic SVL, and to present the authors' recommendations.

The diagnostic accuracy of realtime teledermatology was measured using two different video cameras. One camera was a relatively low-cost, single-chip device camera 1 , while the other was a more expensive, three-chip camera camera 2 . The diagnosis obtained via the videolink was compared with the diagnosis made in person. Sixty-five new patients referred to a dermatology clinic were examined using camera 1 followed by a standard face-to-face consultation on the same day. A further 65 patients were examined using camera 2 and the same procedure implemented. Seventy-six per cent of conditions were correctly diagnosed by telemedicine using camera 2 compared with 62 using camera 1. A working differential diagnosis was obtained in 12 of cases using camera 2 compared with 14 using camera 1. The percentage of `no diagnosis`, wrong and missed diagnoses was halved using camera 2 compared with camera 1. These results suggest that the performance of the more expensive camera was superior for realtime teledermatology.
