With the aid of a 6 mm 0 degree stereo-endoscope supplied with a 100 Hz monitor and high-speed liquid crystal shutter, three-dimensional endoscopy of the upper airway was realized for the first time. The equipment used is based on alternating sequential projections of left and right eye images on a single tv screen. Two high-speed liquid crystal stereo switches (LCSS) are integrated in glasses and a rapid switching time of 100 microseconds is used. In a comparative study this innovative endoscopic technique was tested for its practicability in sinus surgery and endoscopy of the upper airway. With this equipment an excellent view was obtained of the pharynx, larynx and trachea. For sinus surgery, however, a stereoendoscope with smaller dimensions has to be developed.
借助配备100赫兹监视器和高速液晶快门的6毫米0度立体内窥镜，首次实现了上气道的三维内窥镜检查。所使用的设备基于左右眼图像在单个电视屏幕上的交替顺序投影。两个高速液晶立体开关（LCSS）集成在眼镜中，并使用了100微秒的快速切换时间。在一项对比研究中，对这种创新的内窥镜技术在鼻窦手术和上气道内窥镜检查中的实用性进行了测试。使用该设备可以清晰地看到咽部、喉部和气管。然而，对于鼻窦手术，必须开发尺寸更小的立体内窥镜。
