Selection of Video Cameras for Stroboscopic Videolaryngoscopy

Abstract

Stroboscopic evaluation for the analysis of laryngeal function and disease has been reemphasized recently and its routine clinical use recommended. Many have found, however, that it is not always possible to obtain consistently satisfactory video images of stroboscopic laryngoscopy. The problem is related to the low intensity of the xenon light source during stroboscopy. The authors have tried many different video cameras available, along with the Brüel & Kjaer Rhino-Larynx Stroboscope type 4914, and two types of endoscopes (flexible and rigid). The cameras included 1) single tube camera, 2) single chip metal oxide semiconductors (MOS) solid-state camera, 3) single chip charge-coupled devices (CCD) solid-state camera, 4) three-tube camera, and 5) three-chip CCD camera. Currently available video cameras and their adaptability for stroboscopic videolaryngoscopy are discussed.
